How to get a enum value from string in C

Question

I have an enum   public enum baseKey   uint         HKEY CLASSES ROOT   0x80000000      HKEY CURRENT USER   0x80000001      HKEY LOCAL MACHINE   0x80000002      HKEY USERS   0x80000003      HKEY CURRENT CONFIG   0x80000005     How can I  given the string HKEY LOCAL MACHINE  get a value 0x80000002 based on the enum

Using Enum TryParse you don t need the Exception handling   baseKey e   if   Enum TryParse s  out e

With some error handling     uint key   0  string s    HKEY LOCAL MACHINE   try      key    uint Enum Parse typeof baseKey   s     catch ArgumentException         unknown string or s is null

baseKey choice  if  Enum TryParse  HKEY LOCAL MACHINE   out choice          uint value    uint choice            value  is what you re looking for    else      error  the string was not an enum member        Before  NET 4 5  you had to do the following  which is more error-prone and throws an exception when an invalid string is passed    uint Enum Parse typeof baseKey    HKEY LOCAL MACHINE

Alternate solution can be   baseKey hKeyLocalMachine   baseKey HKEY LOCAL MACHINE  uint value    uint hKeyLocalMachine    Or just   uint value    uint baseKey HKEY LOCAL MACHINE

var value    uint  Enum Parse typeof baseKey    HKEY LOCAL MACHINE

User · Answer

var value    uint Enum Parse typeof basekey    HKEY LOCAL MACHINE   true     This code snippet illustrates obtaining an enum value from a string  To convert from a string  you need to use the static Enum Parse   method  which takes 3 parameters  The first is the type of enum you want to consider  The syntax is the keyword typeof   followed by the name of the enum class in brackets  The second parameter is the string to be converted  and the third parameter is a bool indicating whether you should ignore case while doing the conversion    Finally  note that Enum Parse   actually returns an object reference  that means you need to explicitly convert this to the required enum type string int etc    Thank you
