method takes any enum

Question

hi
how to get this functionality:

public static void GetEnum(string txt, out Enum result)
    {
          Enum.TryParse<value.GetType()>(txt, out value); // error
    }

thanks in advance

Answer 1

You can't use value.GetType() when you use a generics method. The generics type needs to determined at compile time.

This means you need to make your method generics.

public static void GetEnum<T>(string txt, out T result) where T : struct
{
    Enum.TryParse(txt, out result);
}

The Enum.TryParse method only accepts types that are structs so you need to add a generic constraint (where T : struct) to make your code compile.

I suggest you return the result instead of using out.

public static T GetEnum<T>(string txt) where T : struct
{
    Enum.TryParse(txt, out T result);
    return result;
}

So you can use your method like this:

var result = GetEnum<MyEnum>("Value");
