[c#] Casting string to enum

I'm reading file content and take string at exact location like this

 string fileContentMessage = File.ReadAllText(filename).Substring(411, 3);

Output will always be either Ok or Err

On the other side I have MyObject which have ContentEnum like this

public class MyObject

    {
      public enum ContentEnum { Ok = 1, Err = 2 };        
      public ContentEnum Content { get; set; }
    }

Now, on the client side I want to use code like this (to cast my string fileContentMessage to Content property)

string fileContentMessage = File.ReadAllText(filename).Substring(411, 3);

    MyObject myObj = new MyObject ()
    {
       Content = /// ///,
    };

This question is related to c# string casting enums

The answer is


Have a look at using something like

Enum.TryParse

Converts the string representation of the name or numeric value of one or more enumerated constants to an equivalent enumerated object. A parameter specifies whether the operation is case-sensitive. The return value indicates whether the conversion succeeded.

or

Enum.Parse

Converts the string representation of the name or numeric value of one or more enumerated constants to an equivalent enumerated object.


As an extra, you can take the Enum.Parse answers already provided and put them in an easy-to-use static method in a helper class.

public static T ParseEnum<T>(string value)
{
    return (T)Enum.Parse(typeof(T), value, ignoreCase: true);
}

And use it like so:

{
   Content = ParseEnum<ContentEnum>(fileContentMessage);
};

Especially helpful if you have lots of (different) Enums to parse.


.NET 4.0+ has a generic Enum.TryParse

ContentEnum content;
Enum.TryParse(fileContentMessage, out content);
