Question

If I have the following:

public enum TYPE
{
   One = 1,
   Two = 2,
   Three = 3
}

When I do:

 var a = TYPE.One;

I would like it to populate the variable a with a string in the format “01”. In other words two digits with a leading zero.

Is it possible to do this by assigning some method to the SomeEnum? I realized I could use TYPE.One.ToString(“00”)but I would like to have it self-contained in the enum and something very simple to use.

Answer 1

can do something like this :

public static class Ext {

    public static string ToMyString(this Enumer en ) {
         return ((int)en).ToString("00");
    }
}

and after use this like:

public enum TYPE { One = 1, Two = 2, Three = 3 }
Type t = TYPE.One; 

string s = t.ToMyString();

Yes, conceptually it’s the same as like declaring a string , but it’s hidden inside extension method.

Other solution is: to simply avoid, at this point, using enums in that way.
