#1,025 – Converting between enum Types

You can convert between two different enum types as long as they both use the same underlying type (e.g. int).  You use an explicit cast to do the conversion.

Assuming two enum types that by default use int as their underlying type, e.g.:

    public enum Day { Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, Saturday };
    public enum Dinner { Sausages, Mutton, Tacos, Wontons, ThinMints, FriedEggs, Sandwiches }

You can convert between them using a simple cast:

            Day today = Day.Monday;
            Dinner menuTonight = (Dinner)today;
            Console.WriteLine("Today is {0} and I'm having {1} for dinner", today, menuTonight);
