Question

I have the following Enum:

public enum ContentKey {
    Menu = 0,
    Article = 1,
    Topic = 2
};

When I use the Enum I have been doing the following:

((int)ContentKey.Topic).ToString("D2")

Is there some way that I could create an extension to the Enum so I didn’t have to code the above?

Answer 1

You can use extension methods:

public static class Ext
{
    public static string ToFormattedString(this ContentKey key, string format)
    {
        //do staff
    }
}

Usage:

ContentKey.Topic.ToFormattedString("D2")
