Total number of items defined in an enum

Question

How can I get the number of items defined in an enum?

Answer 1

If you find yourself writing the above solution as often as I do then you could implement it as a generic:

public static int GetEnumEntries() where T : struct, IConvertible 
{
    if (!typeof(T).IsEnum)
        throw new ArgumentException("T must be an enumerated type");

    return Enum.GetNames(typeof(T)).Length;
}
