#463 – Enumerated Values Can Be Any Constant Expression

When you define an enum, the individual values can be implicitly defined (one greater than the previous value), assigned to a constant, or assigned to any constant expression.

In the definition of the Moods enumerated type below, constant expressions are used for some of the values.

        public const int HappyFactor = 42;

        public enum Moods
            NOMOOD = 0,
            Ambivalent = 1,
            Crabby = 10,
            Grouchy = Crabby - 1,
            Happy = HappyFactor,
            SuperHappy = 2 * Happy
