String representation of an Enum

Question

I have the following enumeration   public enum AuthenticationMethod       FORMS   1      WINDOWSAUTHENTICATION   2      SINGLESIGNON   3     The problem however is that I need the word  FORMS  when I ask for AuthenticationMethod FORMS and not the id 1   I have found the following solution for this problem  link    First I need to create a custom attribute called  StringValue    public class StringValue   System Attribute       private readonly string  value       public StringValue string value                 value   value             public string Value               get   return  value               Then I can add this attribute to my enumerator   public enum AuthenticationMethod        StringValue  FORMS        FORMS   1       StringValue  WINDOWS        WINDOWSAUTHENTICATION   2       StringValue  SSO        SINGLESIGNON   3     And of course I need something to retrieve that StringValue   public static class StringEnum       public static string GetStringValue Enum value                string output   null          Type type   value GetType               Check first in our cached results               Look for our  StringValueAttribute              in the field s custom attributes          FieldInfo fi   type GetField value ToString             StringValue   attrs              fi GetCustomAttributes typeof StringValue                                      false  as StringValue            if  attrs Length  gt  0                        output   attrs 0  Value                     return output            Good now I ve got the tools to get a string value for an enumerator  I can then use it like this   string valueOfAuthenticationMethod   StringEnum GetStringValue AuthenticationMethod FORMS     Okay now all of these work like a charm but I find it a whole lot of work  I was wondering if there is a better solution for this   I also tried something with a dictionary and static properties but that wasn t better either

Here is yet another way to accomplish the task of associating strings with enums:

struct DATABASE {
    public enum enums {NOTCONNECTED, CONNECTED, ERROR}
    static List<string> strings =
        new List<string>() {"Not Connected", "Connected", "Error"};

    public string GetString(DATABASE.enums value) {
        return strings[(int)value];
    }
}

This method is called like this:

public FormMain() {
    DATABASE dbEnum;

    string enumName = dbEnum.GetString(DATABASE.enums.NOTCONNECTED);
}

You can group related enums in their own struct. Since this method uses the enum type, you can use Intellisense to display the list of enums when making the GetString() call.

You can optionally use the new operator on the DATABASE struct. Not using it means the strings List is not allocated until the first GetString() call is made.

Unfortunately reflection to get attributes on enums is quite slow   See this question  Anyone know a quick way to get to custom attributes on an enum value   The  ToString   is quite slow on enums too   You can write extension methods for enums though   public static string GetName  this MyEnum input         switch   input             case MyEnum WINDOWSAUTHENTICATION              return  Windows             and so on           This isn t great  but will be quick and not require the reflection for attributes or field name     C 6 Update  If you can use C 6 then the new nameof operator works for enums  so nameof MyEnum WINDOWSAUTHENTICATION  will be converted to  WINDOWSAUTHENTICATION  at compile time  making it the quickest way to get enum names   Note that this will convert the explicit enum to an inlined constant  so it doesn t work for enums that you have in a variable  So   nameof AuthenticationMethod FORMS      FORMS    But     var myMethod   AuthenticationMethod FORMS  nameof myMethod      myMethod

I use the Description attribute from the System ComponentModel namespace   Simply decorate the enum and then use this code to retrieve it   public static string GetDescription lt T gt  this object enumerationValue              where T   struct                       Type type   enumerationValue GetType                if   type IsEnum                                throw new ArgumentException  EnumerationValue must be of Enum type    enumerationValue                                 Tries to find a DescriptionAttribute for a potential friendly name               for the enum             MemberInfo   memberInfo   type GetMember enumerationValue ToString                 if  memberInfo    null  amp  amp  memberInfo Length  gt  0                                object   attrs   memberInfo 0  GetCustomAttributes typeof DescriptionAttribute   false                    if  attrs    null  amp  amp  attrs Length  gt  0                                          Pull out the description value                     return   DescriptionAttribute attrs 0   Description                                                If we have no description attribute  just return the ToString of the enum             return enumerationValue ToString                 As an example   public enum Cycle   int               Description  Daily Cycle       Daily   1     Weekly     Monthly     This code nicely caters for enums where you don t need a  Friendly name  and will return just the  ToString   of the enum

I use an extension method    public static class AttributesHelperExtension               public static string ToDescription this Enum value                        var da    DescriptionAttribute    value GetType   GetField value ToString     GetCustomAttributes typeof DescriptionAttribute   false               return da Length  gt  0   da 0  Description   value ToString                  Now decorate the enum with    public enum AuthenticationMethod        Description  FORMS        FORMS   1       Description  WINDOWSAUTHENTICATION        WINDOWSAUTHENTICATION   2       Description  SINGLESIGNON         SINGLESIGNON   3     When you call   AuthenticationMethod FORMS ToDescription   you will get  FORMS

If you think about the problem we re trying to solve  it s not an enum we need at all   We need an object that allows a certain number of values to be associated with eachother  in other words  to define a class   Jakub   turc s type-safe enum pattern is the best option I see here   Look at it    It has a private constructor so only the class itself can define the allowed values  It is a sealed class so values can t be modifed through inheritence  It is type-safe  allowing your methods to require only that type  There is no reflection performance hit incurred by accessing the values  And lastly  it can be modified to associate more than two fields together  for example a Name  Description  and a numeric Value

I agree with Keith  but I can t vote up  yet    I use a static method and swith statement to return exactly what I want  In the database I store tinyint and my code only uses the actual enum  so the strings are for UI requirements  After numerous testing this resulted in the best performance and most control over the output   public static string ToSimpleString this enum         switch  enum                  case ComplexForms               return  ComplexForms                break            public static string ToFormattedString this enum         switch  enum                  case ComplexForms               return  Complex Forms                break             However  by some accounts  this leads to a possible maintenance nightmare and some code smell  I try to keep an eye for enums that are long and a lot of enums  or those that change frequently  Otherwise  this has been a great solution for me

I use a combination of several of the suggestions above  combined with some caching   Now  I got the idea from some code that I found somewhere on the net  but I can neither remember where I got it or find it   So if anyone ever finds something that looks similar please comment with the attribution   Anyway  the usage involves the type converters  so if you are binding to the UI it  just works    You can extended with Jakub s pattern for quick code lookup by initializing from the type converter into the static methods   The base usage would look like this   TypeConverter typeof CustomEnumTypeConverter lt MyEnum gt     public enum MyEnum          The custom type converter will use the description attribute      Description  A custom description        ValueWithCustomDescription         This will be exposed exactly     Exact     The code for the custom enum type converter follows   public class CustomEnumTypeConverter lt T gt    EnumConverter     where T   struct       private static readonly Dictionary lt T string gt  s toString          new Dictionary lt T  string gt          private static readonly Dictionary lt string  T gt  s toValue          new Dictionary lt string  T gt          private static bool s isInitialized       static CustomEnumTypeConverter                 System Diagnostics Debug Assert typeof T  IsEnum             The custom enum class must be used with an enum type                public CustomEnumTypeConverter     base typeof T                 if   s isInitialized                        Initialize                s isInitialized   true                       protected void Initialize                 foreach  T item in Enum GetValues typeof T                          string description   GetDescription item               s toString item    description              s toValue description    item                       private static string GetDescription T optionValue                var optionDescription   optionValue ToString            var optionInfo   typeof T  GetField optionDescription           if  Attribute IsDefined optionInfo  typeof DescriptionAttribute                          var attribute                   DescriptionAttribute Attribute                   GetCustomAttribute optionInfo  typeof DescriptionAttribute                return attribute Description                    return optionDescription             public override object ConvertTo ITypeDescriptorContext context          System Globalization CultureInfo culture          object value  Type destinationType                var optionValue    T value           if  destinationType    typeof string   amp  amp               s toString ContainsKey optionValue                         return s toString optionValue                      return base ConvertTo context  culture  value  destinationType              public override object ConvertFrom ITypeDescriptorContext context          System Globalization CultureInfo culture  object value                var stringValue   value as string           if   string IsNullOrEmpty stringValue   amp  amp  s toValue ContainsKey stringValue                         return s toValue stringValue                      return base ConvertFrom context  culture  value

I know pretty well that this question have already been answered and that the OP is already happy with the accepted answer  But I found most of the answers  including the accepted one  to be a little bit more complicated   I have a project which gave me a situation like this and I was able to achieve it this way   First  you have to consider the casing of your enum names   public enum AuthenticationMethod       Forms   1      WindowsAuthentication   2      SingleSignOn   3     Then  have this extension   using System Text RegularExpression   public static class AnExtension       public static string Name this Enum value                string strVal   value ToString            try                       return Regex Replace strVal     a-z    A-Z       1  2                      catch                             return strVal            Through this you can turn your every enum name to its string representation with each word separated with a space  Ex   AuthenticationMethod am   AuthenticationMethod WindowsAuthentication  MessageBox Show am Name

If you think about the problem we re trying to solve  it s not an enum we need at all   We need an object that allows a certain number of values to be associated with eachother  in other words  to define a class   Jakub   turc s type-safe enum pattern is the best option I see here   Look at it    It has a private constructor so only the class itself can define the allowed values  It is a sealed class so values can t be modifed through inheritence  It is type-safe  allowing your methods to require only that type  There is no reflection performance hit incurred by accessing the values  And lastly  it can be modified to associate more than two fields together  for example a Name  Description  and a numeric Value

You can reference the name rather than the value by using ToString    Console WriteLine  Auth method   0    AuthenticationMethod Forms ToString       The documentation is here   http   msdn microsoft com en-us library 16c1xs4z aspx     and if you name your enums in Pascal Case  as I do - such as ThisIsMyEnumValue   1 etc   then you could use a very simple regex to print the friendly form   static string ToFriendlyCase this string EnumString        return Regex Replace EnumString          A-Z        1        which can easily be called from any string   Console WriteLine  ConvertMyCrazyPascalCaseSentenceToFriendlyCase  ToFriendlyCase       Outputs      Convert My Crazy Pascal Case Sentence To Friendly Case   That saves running all the way around the houses creating custom attributes and attaching them to your enums or using lookup tables to marry an enum value with a friendly string and best of all it s self managing and can be used on any Pascal Case string which is infinitely more reusable  Of course  it doesn t allow you to have a different friendly name than your enum which your solution does provide   I do like your original solution though for more complex scenarios though   You could take your solution one step further and make your GetStringValue an extension method of your enum and then you wouldn t need to reference it like StringEnum GetStringValue     public static string GetStringValue this AuthenticationMethod value      string output   null    Type type   value GetType      FieldInfo fi   type GetField value ToString       StringValue   attrs   fi GetCustomAttributes typeof StringValue   false  as StringValue      if  attrs Length  gt  0      output   attrs 0  Value    return output      You could then access it easily straight from your enum instance   Console WriteLine AuthenticationMethod SSO GetStringValue

When I m confronted with this problem  there are a couple of questions that I try to find the answers to first    Are the names of my enum values sufficiently friendly for the purpose  or do I need to provide friendlier ones  Do I need to round-trip   That is  will I need to take text values and parse them into enum values  Is this something I need to do for many enums in my project  or just one  What kind of UI elements will I be presenting this information in - in particular  will I be binding to the UI  or using property sheets  Does this need to be localizable    The simplest way to do this is with Enum GetValue  and support round-tripping using Enum Parse    It s also often worth building a TypeConverter  as Steve Mitcham suggests  to support UI binding    It s not necessary to build a TypeConverter when you re using property sheets  which is one of the nice things about property sheets   Though lord knows they have their own issues    In general  if the answers to the above questions suggest that s not going to work  my next step is to create and populate a static Dictionary lt MyEnum  string gt   or possibly a Dictionary lt Type  Dictionary lt int  string gt  gt    I tend to skip the intermediate decorate-the-code-with-attributes step because what s usually coming down the pike next is the need to change the friendly values after deployment  often  but not always  because of localization

You can declare enum and the dictionary in which the key will be the value of the enumeration  In the future  you can refer to the dictionary to get the value  Thus  it will be possible to pass parameters to functions as the type of enum  but to get the real value from the dictionary   using System  using System Collections Generic   namespace console test       class Program                region SaveFormat         internal enum SaveFormat                       DOCX              PDF                    internal static Dictionary lt SaveFormat string gt  DictSaveFormat   new Dictionary lt SaveFormat  string gt                          SaveFormat DOCX  This is value for DOCX enum item                   SaveFormat PDF  This is value for PDF enum item                        internal static void enum value test SaveFormat save format                        Console WriteLine DictSaveFormat save format                       endregion          internal static void Main string   args                        enum value test SaveFormat DOCX    Output  This is value for DOCX enum item             Console Write  Press any key to continue                       Console ReadKey true

Well  after reading all of the above I feel that the guys have over complicated the issue of transforming enumerators into strings  I liked the idea of having attributes over enumerated fields but i think that attributes are mainly used for Meta-data  but in your case i think that all you need is some sort of localization   public enum Color    Red   1  Green   2  Blue   3    public static EnumUtils       public static string GetEnumResourceString object enumValue                Type enumType   enumValue GetType            string value   Enum GetName enumValue GetType    enumValue           string resourceKey   String Format   0   1    enumType Name  value           string result   Resources Enums ResourceManager GetString resourceKey           if  string IsNullOrEmpty result                         result   String Format   0    value                     return result            Now if we try to call the above method we can call it this way   public void Foo       var col   Color Red    Console WriteLine  EnumUtils GetEnumResourceString  col        All you need to do is just create a resource file containing all the enumerator values and the corresponding strings   Resource Name          Resource Value Color Red              My String Color in Red Color Blue             Blueeey Color Green            Hulk Color   What is actually very nice about that is that it will be very helpful if you need your application to be localized  since all you need to do is just create another resource file with your new language  and Voe-la

Update  Visiting this page  8 years later  after not touching C  for a long while  looks like my answer is no longer the best solution  I really like the converter solution tied with attribute-functions   If you are reading this  please make sure you also check out other answers   hint  they are above this one     As most of you  I really liked the selected answer by Jakub   turc  but I also really hate to copy-paste code  and try to do it as little as I can   So I decided I wanted an EnumBase class from which most of the functionality is inherited built-in  leaving me to focus on the content instead of behavior   The main problem with this approach is based on the fact that although Enum values are type-safe instances  the interaction is with the Static implementation of the Enum Class type  So with a little help of generics magic  I think I finally got the correct mix  Hope someone finds this as useful as I did   I ll start with Jakub s example  but using inheritance and generics   public sealed class AuthenticationMethod   EnumBase lt AuthenticationMethod  int gt        public static readonly AuthenticationMethod FORMS           new AuthenticationMethod 1   FORMS        public static readonly AuthenticationMethod WINDOWSAUTHENTICATION           new AuthenticationMethod 2   WINDOWS        public static readonly AuthenticationMethod SINGLESIGNON           new AuthenticationMethod 3   SSN         private AuthenticationMethod int Value  String Name            base  Value  Name           public new static IEnumerable lt AuthenticationMethod gt  All       get   return EnumBase lt AuthenticationMethod  int gt  All          public static explicit operator AuthenticationMethod string str        return Parse str         And here is the base class   using System  using System Collections Generic  using System Linq     for the  AsEnumerable   method call     E is the derived type-safe-enum class    - this allows all static members to be truly unique to the specific      derived class public class EnumBase lt E  T gt  where E  EnumBase lt E  T gt         region Instance code     public T Value   get  private set        public string Name   get  private set         protected EnumBase T EnumValue  string Name                Value   EnumValue          this Name   Name          mapping Add Name  this              public override string ToString     return Name         endregion       region Static tools     static private readonly Dictionary lt string  EnumBase lt E  T gt  gt  mapping      static EnumBase     mapping   new Dictionary lt string  EnumBase lt E  T gt  gt           protected static E Parse string name                EnumBase lt E  T gt  result          if  mapping TryGetValue name  out result                         return  E result                     throw new InvalidCastException                 This is protected to force the child class to expose it s own static        method         By recreating this static method at the derived class  static        initialization will be explicit  promising the mapping dictionary        will never be empty when this method is called      protected static IEnumerable lt E gt  All       get   return mapping Values AsEnumerable   Cast lt E gt              endregion

I use the Description attribute from the System ComponentModel namespace   Simply decorate the enum and then use this code to retrieve it   public static string GetDescription lt T gt  this object enumerationValue              where T   struct                       Type type   enumerationValue GetType                if   type IsEnum                                throw new ArgumentException  EnumerationValue must be of Enum type    enumerationValue                                 Tries to find a DescriptionAttribute for a potential friendly name               for the enum             MemberInfo   memberInfo   type GetMember enumerationValue ToString                 if  memberInfo    null  amp  amp  memberInfo Length  gt  0                                object   attrs   memberInfo 0  GetCustomAttributes typeof DescriptionAttribute   false                    if  attrs    null  amp  amp  attrs Length  gt  0                                          Pull out the description value                     return   DescriptionAttribute attrs 0   Description                                                If we have no description attribute  just return the ToString of the enum             return enumerationValue ToString                 As an example   public enum Cycle   int               Description  Daily Cycle       Daily   1     Weekly     Monthly     This code nicely caters for enums where you don t need a  Friendly name  and will return just the  ToString   of the enum

A lot of great answers here but in my case did not solve what I wanted out of an  string enum   which was    Usable in a switch statement       e g  switch myEnum  Can be used in function parameters e g  foo myEnum type  Can be referenced                  e g  myEnum FirstElement I can use strings                  e g  foo  FirstElement      foo myEnum FirstElement    1 2  amp  4 can actually be solved with a C  Typedef of a string  since strings are switchable in c    3 can be solved by static const strings  So if you have the same needs  this is the simplest approach   public sealed class Types        private readonly String name       private Types String name                this name   name              public override String ToString                 return name             public static implicit operator Types string str                return new Types str              public static implicit operator string Types str                return str ToString                 region enum      public const string DataType    Data       public const string ImageType    Image       public const string Folder    Folder        endregion      This allows for example       public TypeArgs Types SelectedType                Types SelectedType   SelectedType         and   public TypeObject CreateType Types type                switch  type                         case Types ImageType                                   break               case Types DataType                                  break                     Where CreateType can be called with a string or a type  However the downside is that any string is automatically a valid enum  this could be modified but then it would require some kind of init function   or possibly make they explicit cast internal   Now if an int value was important to you  perhaps for comparison speed   you could use some ideas from Jakub   turc fantastic answer and do something a bit crazy  this is my stab at it       public sealed class Types       private static readonly Dictionary lt string  Types gt  strInstance   new Dictionary lt string  Types gt         private static readonly Dictionary lt int  Types gt  intInstance   new Dictionary lt int  Types gt          private readonly String name      private static int layerTypeCount   0      private int value      private Types String name                this name   name          value   layerTypeCount            strInstance name    this          intInstance value    this             public override String ToString                 return name              public static implicit operator Types int val                Types result          if  intInstance TryGetValue val  out result               return result          else             throw new InvalidCastException               public static implicit operator Types string str                Types result          if  strInstance TryGetValue str  out result                         return result                    else                       result   new Types str               return result                       public static implicit operator string Types str                return str ToString               public static bool operator    Types a  Types b                return a value    b value            public static bool operator    Types a  Types b                return a value    b value              region enum      public const string DataType    Data       public const string ImageType    Image         endregion      but of course  Types bob   4   would be meaningless unless you had initialized them first which would sort of defeat the point      But in theory TypeA    TypeB would be quicker

For larger string enum sets  the listed examples can become tiresome  If you want a list of status codes  or a list of other string based enums  an attribute system is annoying to use  and a static class with instances of itself is annoying to configure  For my own solution  I make use of T4 templating to make it easier to have string-backed enums  The result comes out similar to how the HttpMethod class works   You can use it like this       string statusCode   ResponseStatusCode SUCCESS     Automatically converts to string when needed     ResponseStatusCode codeByValueOf   ResponseStatusCode ValueOf statusCode      Returns null if not found         Implements TypeConverter so you can use it with string conversion methods      var converter   System ComponentModel TypeDescriptor GetConverter typeof ResponseStatusCode        ResponseStatusCode code    ResponseStatusCode  converter ConvertFromInvariantString statusCode           You can get a full list of the values     bool canIterateOverValues   ResponseStatusCode Values Any             Comparisons are by value of the  Name  property  Not by memory pointer location      bool implementsByValueEqualsEqualsOperator    SUCCESS     ResponseStatusCode SUCCESS     You start out with a Enum tt file     lt    include file  StringEnum ttinclude    gt     lt    public static class Configuration       public static readonly string Namespace    YourName Space       public static readonly string EnumName    ResponseStatusCode       public static readonly bool IncludeComments   true       public static readonly object Nodes   new               SUCCESS    The response was successful            NON SUCCESS    The request was not successful            RESOURCE IS DISCONTINUED    The resource requested has been discontinued and can no longer be accessed              gt    Then  you add in your StringEnum ttinclude file    lt    template debug  false  hostspecific  false

old post but     The answer to this may actually be very simple  Use Enum ToString   function  There are 6 overloads of this function  you can use Enum Tostring  F   or Enum ToString   to return the string value  No need to bother with anything else  Here is a working Demo  Note that this solution may not work for all compilers  this demo does not work as expected  but at least it works for the latest compiler

When I m confronted with this problem  there are a couple of questions that I try to find the answers to first    Are the names of my enum values sufficiently friendly for the purpose  or do I need to provide friendlier ones  Do I need to round-trip   That is  will I need to take text values and parse them into enum values  Is this something I need to do for many enums in my project  or just one  What kind of UI elements will I be presenting this information in - in particular  will I be binding to the UI  or using property sheets  Does this need to be localizable    The simplest way to do this is with Enum GetValue  and support round-tripping using Enum Parse    It s also often worth building a TypeConverter  as Steve Mitcham suggests  to support UI binding    It s not necessary to build a TypeConverter when you re using property sheets  which is one of the nice things about property sheets   Though lord knows they have their own issues    In general  if the answers to the above questions suggest that s not going to work  my next step is to create and populate a static Dictionary lt MyEnum  string gt   or possibly a Dictionary lt Type  Dictionary lt int  string gt  gt    I tend to skip the intermediate decorate-the-code-with-attributes step because what s usually coming down the pike next is the need to change the friendly values after deployment  often  but not always  because of localization

Well  after reading all of the above I feel that the guys have over complicated the issue of transforming enumerators into strings  I liked the idea of having attributes over enumerated fields but i think that attributes are mainly used for Meta-data  but in your case i think that all you need is some sort of localization   public enum Color    Red   1  Green   2  Blue   3    public static EnumUtils       public static string GetEnumResourceString object enumValue                Type enumType   enumValue GetType            string value   Enum GetName enumValue GetType    enumValue           string resourceKey   String Format   0   1    enumType Name  value           string result   Resources Enums ResourceManager GetString resourceKey           if  string IsNullOrEmpty result                         result   String Format   0    value                     return result            Now if we try to call the above method we can call it this way   public void Foo       var col   Color Red    Console WriteLine  EnumUtils GetEnumResourceString  col        All you need to do is just create a resource file containing all the enumerator values and the corresponding strings   Resource Name          Resource Value Color Red              My String Color in Red Color Blue             Blueeey Color Green            Hulk Color   What is actually very nice about that is that it will be very helpful if you need your application to be localized  since all you need to do is just create another resource file with your new language  and Voe-la

User · Answer

In your question you never said that you actually need the numeric value of the enum anywhere   If you do not and just need an enum of type string  which is not an integral type so can not be a base of enum  here is a way       static class AuthenticationMethod               public static readonly string             FORMS    Forms               WINDOWSAUTHENTICATION    WindowsAuthentication           you can use the same syntax as enum to reference it  if  bla    AuthenticationMethod FORMS    It will be a bit slower than with numeric values  comparing strings instead of numbers  but on the plus side it is not using reflection  slow  to access the string

I know pretty well that this question have already been answered and that the OP is already happy with the accepted answer  But I found most of the answers  including the accepted one  to be a little bit more complicated   I have a project which gave me a situation like this and I was able to achieve it this way   First  you have to consider the casing of your enum names   public enum AuthenticationMethod       Forms   1      WindowsAuthentication   2      SingleSignOn   3     Then  have this extension   using System Text RegularExpression   public static class AnExtension       public static string Name this Enum value                string strVal   value ToString            try                       return Regex Replace strVal     a-z    A-Z       1  2                      catch                             return strVal            Through this you can turn your every enum name to its string representation with each word separated with a space  Ex   AuthenticationMethod am   AuthenticationMethod WindowsAuthentication  MessageBox Show am Name

For larger string enum sets  the listed examples can become tiresome  If you want a list of status codes  or a list of other string based enums  an attribute system is annoying to use  and a static class with instances of itself is annoying to configure  For my own solution  I make use of T4 templating to make it easier to have string-backed enums  The result comes out similar to how the HttpMethod class works   You can use it like this       string statusCode   ResponseStatusCode SUCCESS     Automatically converts to string when needed     ResponseStatusCode codeByValueOf   ResponseStatusCode ValueOf statusCode      Returns null if not found         Implements TypeConverter so you can use it with string conversion methods      var converter   System ComponentModel TypeDescriptor GetConverter typeof ResponseStatusCode        ResponseStatusCode code    ResponseStatusCode  converter ConvertFromInvariantString statusCode           You can get a full list of the values     bool canIterateOverValues   ResponseStatusCode Values Any             Comparisons are by value of the  Name  property  Not by memory pointer location      bool implementsByValueEqualsEqualsOperator    SUCCESS     ResponseStatusCode SUCCESS     You start out with a Enum tt file     lt    include file  StringEnum ttinclude    gt     lt    public static class Configuration       public static readonly string Namespace    YourName Space       public static readonly string EnumName    ResponseStatusCode       public static readonly bool IncludeComments

 The resource requested has been discontinued and can no longer be accessed              gt    Then  you add in your StringEnum ttinclude file    lt    template debug  false  hostspecific  false

I agree with Keith  but I can t vote up  yet    I use a static method and swith statement to return exactly what I want  In the database I store tinyint and my code only uses the actual enum  so the strings are for UI requirements  After numerous testing this resulted in the best performance and most control over the output   public static string ToSimpleString this enum         switch  enum                  case ComplexForms               return  ComplexForms                break            public static string ToFormattedString this enum         switch  enum                  case ComplexForms               return  Complex Forms                break             However  by some accounts  this leads to a possible maintenance nightmare and some code smell  I try to keep an eye for enums that are long and a lot of enums  or those that change frequently  Otherwise  this has been a great solution for me

The approach i found for internationalization of Enums or getting text of Enums from respective Resource files is to create an attribute class by inheriting DescriptionAttribute class   public class EnumResourceAttribute   DescriptionAttribute        public Type ResourceType   get  private set        public string ResourceName   get  private set        public int SortOrder   get  private set        public EnumResourceAttribute Type ResourceType                           string ResourceName                           int SortOrder                 this ResourceType   ResourceType          this ResourceName   ResourceName          this SortOrder   SortOrder            Create another Static class that will provide extension methods for GetString and GetStrings    public static class EnumHelper       public static string GetString this Enum value                EnumResourceAttribute ea           EnumResourceAttribute value GetType   GetField value ToString             GetCustomAttributes typeof EnumResourceAttribute   false            FirstOrDefault            if  ea    null                        PropertyInfo pi   ea ResourceType               GetProperty CommonConstants ResourceManager               if  pi    null                                ResourceManager rm    ResourceManager pi                  GetValue null  null                   return rm GetString ea ResourceName                                    return string Empty              public static IList GetStrings this Type enumType                List lt string gt  stringList   new List lt string gt             FieldInfo   fiArray   enumType GetFields            foreach  FieldInfo fi in fiArray                        EnumResourceAttribute ea                    EnumResourceAttribute fi                       GetCustomAttributes typeof EnumResourceAttribute   false                        FirstOrDefault                if  ea    null                                PropertyInfo pi   ea ResourceType                                      GetProperty CommonConstants ResourceManager                   if  pi    null                                        ResourceManager rm    ResourceManager pi                                            GetValue null  null                       stringList Add rm GetString ea ResourceName                                                      return stringList ToList              And on the elements of your Enum you can write    public enum Priority         EnumResourceAttribute typeof Resources AdviceModule   Resources ResourceNames AdviceCreateAdviceExternaPriorityMemberHigh  1       High        EnumResourceAttribute typeof Resources AdviceModule   Resources ResourceNames AdviceCreateAdviceExternaPriorityMemberRoutine  2       Routine     Where Resources ResourceNames AdviceCreateAdviceExternaPriorityMemberHigh  amp   Resources ResourceNames AdviceCreateAdviceExternaPriorityMemberRoutine are constants in the resource file or you can say the strings whose values can be available in different cultures   If you are implementing your web application in MVC architecture then create a property   private IList result  public IList Result       get               result   typeof Priority  GetStrings            return result            and in your  cshtml file you can just bind the enum to your dropdownlist like     Html DropDownListFor model   gt  Model vwClinicalInfo Priority  new SelectList Model Result     Thanks Ratnesh

I use the Description attribute from the System ComponentModel namespace   Simply decorate the enum and then use this code to retrieve it   public static string GetDescription lt T gt  this object enumerationValue              where T   struct                       Type type   enumerationValue GetType                if   type IsEnum                                throw new ArgumentException  EnumerationValue must be of Enum type    enumerationValue                                 Tries to find a DescriptionAttribute for a potential friendly name               for the enum             MemberInfo   memberInfo   type GetMember enumerationValue ToString                 if  memberInfo    null  amp  amp  memberInfo Length  gt  0                                object   attrs   memberInfo 0  GetCustomAttributes typeof DescriptionAttribute   false                    if  attrs    null  amp  amp  attrs Length  gt  0                                          Pull out the description value                     return   DescriptionAttribute attrs 0   Description                                                If we have no description attribute  just return the ToString of the enum             return enumerationValue ToString                 As an example   public enum Cycle   int               Description  Daily Cycle       Daily   1     Weekly     Monthly     This code nicely caters for enums where you don t need a  Friendly name  and will return just the  ToString   of the enum

When I m confronted with this problem  there are a couple of questions that I try to find the answers to first    Are the names of my enum values sufficiently friendly for the purpose  or do I need to provide friendlier ones  Do I need to round-trip   That is  will I need to take text values and parse them into enum values  Is this something I need to do for many enums in my project  or just one  What kind of UI elements will I be presenting this information in - in particular  will I be binding to the UI  or using property sheets  Does this need to be localizable    The simplest way to do this is with Enum GetValue  and support round-tripping using Enum Parse    It s also often worth building a TypeConverter  as Steve Mitcham suggests  to support UI binding    It s not necessary to build a TypeConverter when you re using property sheets  which is one of the nice things about property sheets   Though lord knows they have their own issues    In general  if the answers to the above questions suggest that s not going to work  my next step is to create and populate a static Dictionary lt MyEnum  string gt   or possibly a Dictionary lt Type  Dictionary lt int  string gt  gt    I tend to skip the intermediate decorate-the-code-with-attributes step because what s usually coming down the pike next is the need to change the friendly values after deployment  often  but not always  because of localization

I created a base class for creating string-valued enums in  NET  It is just one C  file that you can copy  amp  paste into your projects  or install via NuGet package named StringEnum   GitHub Repo

I use the Description attribute from the System ComponentModel namespace   Simply decorate the enum and then use this code to retrieve it   public static string GetDescription lt T gt  this object enumerationValue              where T   struct                       Type type   enumerationValue GetType                if   type IsEnum                                throw new ArgumentException  EnumerationValue must be of Enum type    enumerationValue                                 Tries to find a DescriptionAttribute for a potential friendly name               for the enum             MemberInfo   memberInfo   type GetMember enumerationValue ToString                 if  memberInfo    null  amp  amp  memberInfo Length  gt  0                                object   attrs   memberInfo 0  GetCustomAttributes typeof DescriptionAttribute   false                    if  attrs    null  amp  amp  attrs Length  gt  0                                          Pull out the description value                     return   DescriptionAttribute attrs 0   Description                                                If we have no description attribute  just return the ToString of the enum             return enumerationValue ToString                 As an example   public enum Cycle   int               Description  Daily Cycle       Daily   1     Weekly     Monthly     This code nicely caters for enums where you don t need a  Friendly name  and will return just the  ToString   of the enum

old post but     The answer to this may actually be very simple  Use Enum ToString   function  There are 6 overloads of this function  you can use Enum Tostring  F   or Enum ToString   to return the string value  No need to bother with anything else  Here is a working Demo  Note that this solution may not work for all compilers  this demo does not work as expected  but at least it works for the latest compiler

I use a combination of several of the suggestions above  combined with some caching   Now  I got the idea from some code that I found somewhere on the net  but I can neither remember where I got it or find it   So if anyone ever finds something that looks similar please comment with the attribution   Anyway  the usage involves the type converters  so if you are binding to the UI it  just works    You can extended with Jakub s pattern for quick code lookup by initializing from the type converter into the static methods   The base usage would look like this   TypeConverter typeof CustomEnumTypeConverter lt MyEnum gt     public enum MyEnum          The custom type converter will use the description attribute      Description  A custom description        ValueWithCustomDescription         This will be exposed exactly     Exact     The code for the custom enum type converter follows   public class CustomEnumTypeConverter lt T gt    EnumConverter     where T   struct       private static readonly Dictionary lt T string gt  s toString          new Dictionary lt T  string gt          private static readonly Dictionary lt string  T gt  s toValue          new Dictionary lt string  T gt          private static bool s isInitialized       static CustomEnumTypeConverter                 System Diagnostics Debug Assert typeof T  IsEnum             The custom enum class must be used with an enum type                public CustomEnumTypeConverter     base typeof T                 if   s isInitialized                        Initialize                s isInitialized   true                       protected void Initialize                 foreach  T item in Enum GetValues typeof T                          string description   GetDescription item               s toString item    description              s toValue description    item                       private static string GetDescription T optionValue                var optionDescription   optionValue ToString            var optionInfo   typeof T  GetField optionDescription           if  Attribute IsDefined optionInfo  typeof DescriptionAttribute                          var attribute                   DescriptionAttribute Attribute                   GetCustomAttribute optionInfo  typeof DescriptionAttribute                return attribute Description                    return optionDescription             public override object ConvertTo ITypeDescriptorContext context          System Globalization CultureInfo culture          object value  Type destinationType                var optionValue    T value           if  destinationType    typeof string   amp  amp               s toString ContainsKey optionValue                         return s toString optionValue                      return base ConvertTo context  culture  value  destinationType              public override object ConvertFrom ITypeDescriptorContext context          System Globalization CultureInfo culture  object value                var stringValue   value as string           if   string IsNullOrEmpty stringValue   amp  amp  s toValue ContainsKey stringValue                         return s toValue stringValue                      return base ConvertFrom context  culture  value

When I am in a situation like that I propose the solution below   And as a consuming class you could have   using System  using System Collections Generic  using System Linq  using System Text   namespace MyApp Dictionaries       class Greek                public static readonly string Alpha    Alpha           public static readonly string Beta    Beta           public static readonly string Gamma    Gamma           public static readonly string Delta    Delta             private static readonly BiDictionary lt int  string gt  Dictionary   new BiDictionary lt int  string gt               static Greek                 Dictionary Add 1  Alpha               Dictionary Add 2  Beta               Dictionary Add 3  Gamma               Dictionary Add 4  Delta                      public static string getById int id               return Dictionary GetByFirst id                      public static int getByValue string value                        return Dictionary GetBySecond value                        And using a bidirectional dictionary   Based on this  https   stackoverflow com a 255638 986160  assuming that the keys will be associated with single values in the dictionary and similar to  https   stackoverflow com a 255630 986160  but a bit more elegant  This dictionary is also enumerable and you can go back and forth from ints to strings  Also you don t have to have any string in your codebase with the exception of this class   using System  using System Collections Generic  using System Linq  using System Text  using System Collections   namespace MyApp Dictionaries        class BiDictionary lt TFirst  TSecond gt    IEnumerable               IDictionary lt TFirst  TSecond gt  firstToSecond   new Dictionary lt TFirst  TSecond gt             IDictionary lt TSecond  TFirst gt  secondToFirst   new Dictionary lt TSecond  TFirst gt              public void Add TFirst first  TSecond second                        firstToSecond Add first  second               secondToFirst Add second  first                      public TSecond this TFirst first                        get   return GetByFirst first                        public TFirst this TSecond second                        get   return GetBySecond second                        public TSecond GetByFirst TFirst first                        return firstToSecond first                      public TFirst GetBySecond TSecond second                        return secondToFirst second                      public IEnumerator GetEnumerator                         return GetFirstEnumerator                       public IEnumerator GetFirstEnumerator                         return firstToSecond GetEnumerator                       public IEnumerator GetSecondEnumerator                         return secondToFirst GetEnumerator

You can reference the name rather than the value by using ToString    Console WriteLine  Auth method   0    AuthenticationMethod Forms ToString       The documentation is here   http   msdn microsoft com en-us library 16c1xs4z aspx     and if you name your enums in Pascal Case  as I do - such as ThisIsMyEnumValue   1 etc   then you could use a very simple regex to print the friendly form   static string ToFriendlyCase this string EnumString        return Regex Replace EnumString          A-Z        1        which can easily be called from any string   Console WriteLine  ConvertMyCrazyPascalCaseSentenceToFriendlyCase  ToFriendlyCase       Outputs      Convert My Crazy Pascal Case Sentence To Friendly Case   That saves running all the way around the houses creating custom attributes and attaching them to your enums or using lookup tables to marry an enum value with a friendly string and best of all it s self managing and can be used on any Pascal Case string which is infinitely more reusable  Of course  it doesn t allow you to have a different friendly name than your enum which your solution does provide   I do like your original solution though for more complex scenarios though   You could take your solution one step further and make your GetStringValue an extension method of your enum and then you wouldn t need to reference it like StringEnum GetStringValue     public static string GetStringValue this AuthenticationMethod value      string output   null    Type type   value GetType      FieldInfo fi   type GetField value ToString       StringValue   attrs   fi GetCustomAttributes typeof StringValue   false  as StringValue      if  attrs Length  gt  0      output   attrs 0  Value    return output      You could then access it easily straight from your enum instance   Console WriteLine AuthenticationMethod SSO GetStringValue

A lot of great answers here but in my case did not solve what I wanted out of an  string enum   which was    Usable in a switch statement       e g  switch myEnum  Can be used in function parameters e g  foo myEnum type  Can be referenced                  e g  myEnum FirstElement I can use strings                  e g  foo  FirstElement      foo myEnum FirstElement    1 2  amp  4 can actually be solved with a C  Typedef of a string  since strings are switchable in c    3 can be solved by static const strings  So if you have the same needs  this is the simplest approach   public sealed class Types        private readonly String name       private Types String name                this name   name              public override String ToString                 return name             public static implicit operator Types string str                return new Types str              public static implicit operator string Types str                return str ToString                 region enum      public const string DataType    Data       public const string ImageType    Image       public const string Folder    Folder        endregion      This allows for example       public TypeArgs Types SelectedType                Types SelectedType   SelectedType         and   public TypeObject CreateType Types type                switch  type                         case Types ImageType                                   break               case Types DataType                                  break                     Where CreateType can be called with a string or a type  However the downside is that any string is automatically a valid enum  this could be modified but then it would require some kind of init function   or possibly make they explicit cast internal   Now if an int value was important to you  perhaps for comparison speed   you could use some ideas from Jakub   turc fantastic answer and do something a bit crazy  this is my stab at it       public sealed class Types       private static readonly Dictionary lt string  Types gt  strInstance   new Dictionary lt string  Types gt         private static readonly Dictionary lt int  Types gt  intInstance   new Dictionary lt int  Types gt          private readonly String name      private static int layerTypeCount   0      private int value      private Types String name                this name   name          value   layerTypeCount            strInstance name    this          intInstance value    this             public override String ToString                 return name              public static implicit operator Types int val                Types result          if  intInstance TryGetValue val  out result               return result          else             throw new InvalidCastException               public static implicit operator Types string str                Types result          if  strInstance TryGetValue str  out result                         return result                    else                       result   new Types str               return result                       public static implicit operator string Types str                return str ToString               public static bool operator    Types a  Types b                return a value    b value            public static bool operator    Types a  Types b                return a value    b value              region enum      public const string DataType    Data       public const string ImageType    Image         endregion      but of course  Types bob   4   would be meaningless unless you had initialized them first which would sort of defeat the point      But in theory TypeA    TypeB would be quicker

The approach i found for internationalization of Enums or getting text of Enums from respective Resource files is to create an attribute class by inheriting DescriptionAttribute class   public class EnumResourceAttribute   DescriptionAttribute        public Type ResourceType   get  private set        public string ResourceName   get  private set        public int SortOrder   get  private set        public EnumResourceAttribute Type ResourceType                           string ResourceName                           int SortOrder                 this ResourceType   ResourceType          this ResourceName   ResourceName          this SortOrder   SortOrder            Create another Static class that will provide extension methods for GetString and GetStrings    public static class EnumHelper       public static string GetString this Enum value                EnumResourceAttribute ea           EnumResourceAttribute value GetType   GetField value ToString             GetCustomAttributes typeof EnumResourceAttribute   false            FirstOrDefault            if  ea    null                        PropertyInfo pi   ea ResourceType               GetProperty CommonConstants ResourceManager               if  pi    null                                ResourceManager rm    ResourceManager pi                  GetValue null  null                   return rm GetString ea ResourceName                                    return string Empty              public static IList GetStrings this Type enumType                List lt string gt  stringList   new List lt string gt             FieldInfo   fiArray   enumType GetFields            foreach  FieldInfo fi in fiArray                        EnumResourceAttribute ea                    EnumResourceAttribute fi                       GetCustomAttributes typeof EnumResourceAttribute   false                        FirstOrDefault                if  ea    null                                PropertyInfo pi   ea ResourceType                                      GetProperty CommonConstants ResourceManager                   if  pi    null                                        ResourceManager rm    ResourceManager pi                                            GetValue null  null                       stringList Add rm GetString ea ResourceName                                                      return stringList ToList              And on the elements of your Enum you can write    public enum Priority         EnumResourceAttribute typeof Resources AdviceModule   Resources ResourceNames AdviceCreateAdviceExternaPriorityMemberHigh  1       High        EnumResourceAttribute typeof Resources AdviceModule   Resources ResourceNames AdviceCreateAdviceExternaPriorityMemberRoutine  2       Routine     Where Resources ResourceNames AdviceCreateAdviceExternaPriorityMemberHigh  amp   Resources ResourceNames AdviceCreateAdviceExternaPriorityMemberRoutine are constants in the resource file or you can say the strings whose values can be available in different cultures   If you are implementing your web application in MVC architecture then create a property   private IList result  public IList Result       get               result   typeof Priority  GetStrings            return result            and in your  cshtml file you can just bind the enum to your dropdownlist like     Html DropDownListFor model   gt  Model vwClinicalInfo Priority  new SelectList Model Result     Thanks Ratnesh

You can declare enum and the dictionary in which the key will be the value of the enumeration  In the future  you can refer to the dictionary to get the value  Thus  it will be possible to pass parameters to functions as the type of enum  but to get the real value from the dictionary   using System  using System Collections Generic   namespace console test       class Program                region SaveFormat         internal enum SaveFormat                       DOCX              PDF                    internal static Dictionary lt SaveFormat string gt  DictSaveFormat   new Dictionary lt SaveFormat  string gt                          SaveFormat DOCX  This is value for DOCX enum item                   SaveFormat PDF  This is value for PDF enum item                        internal static void enum value test SaveFormat save format                        Console WriteLine DictSaveFormat save format                       endregion          internal static void Main string   args                        enum value test SaveFormat DOCX    Output  This is value for DOCX enum item             Console Write  Press any key to continue                       Console ReadKey true

Update  Visiting this page  8 years later  after not touching C  for a long while  looks like my answer is no longer the best solution  I really like the converter solution tied with attribute-functions   If you are reading this  please make sure you also check out other answers   hint  they are above this one     As most of you  I really liked the selected answer by Jakub   turc  but I also really hate to copy-paste code  and try to do it as little as I can   So I decided I wanted an EnumBase class from which most of the functionality is inherited built-in  leaving me to focus on the content instead of behavior   The main problem with this approach is based on the fact that although Enum values are type-safe instances  the interaction is with the Static implementation of the Enum Class type  So with a little help of generics magic  I think I finally got the correct mix  Hope someone finds this as useful as I did   I ll start with Jakub s example  but using inheritance and generics   public sealed class AuthenticationMethod   EnumBase lt AuthenticationMethod  int gt        public static readonly AuthenticationMethod FORMS           new AuthenticationMethod 1   FORMS        public static readonly AuthenticationMethod WINDOWSAUTHENTICATION           new AuthenticationMethod 2   WINDOWS        public static readonly AuthenticationMethod SINGLESIGNON           new AuthenticationMethod 3   SSN         private AuthenticationMethod int Value  String Name            base  Value  Name           public new static IEnumerable lt AuthenticationMethod gt  All       get   return EnumBase lt AuthenticationMethod  int gt  All          public static explicit operator AuthenticationMethod string str        return Parse str         And here is the base class   using System  using System Collections Generic  using System Linq     for the  AsEnumerable   method call     E is the derived type-safe-enum class    - this allows all static members to be truly unique to the specific      derived class public class EnumBase lt E  T gt  where E  EnumBase lt E  T gt         region Instance code     public T Value   get  private set        public string Name   get  private set         protected EnumBase T EnumValue  string Name                Value   EnumValue          this Name   Name          mapping Add Name  this              public override string ToString     return Name         endregion       region Static tools     static private readonly Dictionary lt string  EnumBase lt E  T gt  gt  mapping      static EnumBase     mapping   new Dictionary lt string  EnumBase lt E  T gt  gt           protected static E Parse string name                EnumBase lt E  T gt  result          if  mapping TryGetValue name  out result                         return  E result                     throw new InvalidCastException                 This is protected to force the child class to expose it s own static        method         By recreating this static method at the derived class  static        initialization will be explicit  promising the mapping dictionary        will never be empty when this method is called      protected static IEnumerable lt E gt  All       get   return mapping Values AsEnumerable   Cast lt E gt              endregion

If I m understanding you correctly  you can simply use  ToString   to retrieve the name of the enum from the value  Assuming it s already cast as the Enum   If you had the naked int  lets say from a database or something  you can first cast it to the enum  Both methods below will get you the enum name   AuthenticationMethod myCurrentSetting   AuthenticationMethod FORMS  Console WriteLine myCurrentSetting      Prints  FORMS string name   Enum GetNames typeof AuthenticationMethod    int myCurrentSetting-1   Console WriteLine name      Prints  FORMS   Keep in mind though  the second technique assumes you are using ints and your index is 1 based  not 0 based   The function GetNames also is quite heavy by comparison  you are generating a whole array each time it s called  As you can see in the first technique   ToString   is actually called implicitly  Both of these are already mentioned in the answers of course  I m just trying to clarify the differences between them

When I m confronted with this problem  there are a couple of questions that I try to find the answers to first    Are the names of my enum values sufficiently friendly for the purpose  or do I need to provide friendlier ones  Do I need to round-trip   That is  will I need to take text values and parse them into enum values  Is this something I need to do for many enums in my project  or just one  What kind of UI elements will I be presenting this information in - in particular  will I be binding to the UI  or using property sheets  Does this need to be localizable    The simplest way to do this is with Enum GetValue  and support round-tripping using Enum Parse    It s also often worth building a TypeConverter  as Steve Mitcham suggests  to support UI binding    It s not necessary to build a TypeConverter when you re using property sheets  which is one of the nice things about property sheets   Though lord knows they have their own issues    In general  if the answers to the above questions suggest that s not going to work  my next step is to create and populate a static Dictionary lt MyEnum  string gt   or possibly a Dictionary lt Type  Dictionary lt int  string gt  gt    I tend to skip the intermediate decorate-the-code-with-attributes step because what s usually coming down the pike next is the need to change the friendly values after deployment  often  but not always  because of localization

In your question you never said that you actually need the numeric value of the enum anywhere   If you do not and just need an enum of type string  which is not an integral type so can not be a base of enum  here is a way       static class AuthenticationMethod               public static readonly string             FORMS    Forms               WINDOWSAUTHENTICATION    WindowsAuthentication           you can use the same syntax as enum to reference it  if  bla    AuthenticationMethod FORMS    It will be a bit slower than with numeric values  comparing strings instead of numbers  but on the plus side it is not using reflection  slow  to access the string

If I m understanding you correctly  you can simply use  ToString   to retrieve the name of the enum from the value  Assuming it s already cast as the Enum   If you had the naked int  lets say from a database or something  you can first cast it to the enum  Both methods below will get you the enum name   AuthenticationMethod myCurrentSetting   AuthenticationMethod FORMS  Console WriteLine myCurrentSetting      Prints  FORMS string name   Enum GetNames typeof AuthenticationMethod    int myCurrentSetting-1   Console WriteLine name      Prints  FORMS   Keep in mind though  the second technique assumes you are using ints and your index is 1 based  not 0 based   The function GetNames also is quite heavy by comparison  you are generating a whole array each time it s called  As you can see in the first technique   ToString   is actually called implicitly  Both of these are already mentioned in the answers of course  I m just trying to clarify the differences between them

Try type-safe-enum pattern   public sealed class AuthenticationMethod        private readonly String name      private readonly int value       public static readonly AuthenticationMethod FORMS   new AuthenticationMethod  1   FORMS        public static readonly AuthenticationMethod WINDOWSAUTHENTICATION   new AuthenticationMethod  2   WINDOWS        public static readonly AuthenticationMethod SINGLESIGNON   new AuthenticationMethod  3   SSN                 private AuthenticationMethod int value  String name           this name   name          this value   value             public override String ToString            return name               Update Explicit  or implicit  type conversion can be done by   adding static field with mapping  private static readonly Dictionary lt string  AuthenticationMethod gt  instance   new Dictionary lt string AuthenticationMethod gt        n b  In order that the initialisation of the the  enum member  fields doesn t throw a NullReferenceException when calling the instance constructor  be sure to put the Dictionary field before the  enum member  fields in your class  This is because static field initialisers are called in declaration order  and before the static constructor  creating the weird and necessary but confusing situation that the instance constructor can be called before all static fields have been initialised  and before the static constructor is called   filling this mapping in instance constructor  instance name    this   and adding user-defined type conversion operator  public static explicit operator AuthenticationMethod string str        AuthenticationMethod result      if  instance TryGetValue str  out result           return result      else         throw new InvalidCastException

Here is yet another way to accomplish the task of associating strings with enums:

struct DATABASE {
    public enum enums {NOTCONNECTED, CONNECTED, ERROR}
    static List<string> strings =
        new List<string>() {"Not Connected", "Connected", "Error"};

    public string GetString(DATABASE.enums value) {
        return strings[(int)value];
    }
}

This method is called like this:

public FormMain() {
    DATABASE dbEnum;

    string enumName = dbEnum.GetString(DATABASE.enums.NOTCONNECTED);
}

You can group related enums in their own struct. Since this method uses the enum type, you can use Intellisense to display the list of enums when making the GetString() call.

You can optionally use the new operator on the DATABASE struct. Not using it means the strings List is not allocated until the first GetString() call is made.
