Anyone know a good workaround for the lack of an enum generic constraint?

Question

What I want to do is something like this: I have enums with combined flagged values.

public static class EnumExtension
{
    public static bool IsSet

        

Answer 1

Actually, it is possible, with an ugly trick. However, it cannot be used for extension methods.

public abstract class Enums where Temp : class {
    public static TEnum Parse(string name) where TEnum : struct, Temp {
        return (TEnum)Enum.Parse(typeof(TEnum), name); 
    }
}
public abstract class Enums : Enums { }

Enums.IsSet("Local")

If you want to, you can give Enums a private constructor and a public nested abstract inherited class with Temp as Enum, to prevent inherited versions for non-enums.
