Krzysztof - good catch. I should have been more specific and noted that this approach has only been tested with mutually exclusive elements.

Thanks,

I am doing this to avoid any casts:

public static IEnumerable<TEnum> EnumAsEnumerable<TEnum>()

{

var enumType = typeof(TEnum);

if (enumType == typeof(Enum))

throw new ArgumentException("typeof(TEnum) == System.Enum", "TEnum");

if (!(enumType.IsEnum))

throw new ArgumentException(String.Format("typeof({0}).IsEnum == false", enumType), "TEnum");

return Enum.GetValues(enumType).OfType<TEnum>();

}

Notice what happens when your enum has [FlagsAttribute] on it. This may not be the behavior you want.
