How to build Color Enum?

[Rainer Queck]

Hello NG,

I would like to define a Color Enum like:

public enum MyColorEnum
{
Color1 = Color.Red,
Color2 = Color.Gren,
....
}

Unfortunately this doesn't work.
Is it possible to do some thing like this, and if yes, how?

Thanks for help!

Regards
Rainer

The problem is that a Color cannot be converted to an integral value.

Rainer,

Enumeration values can only use integral types as a base (int, long,
byte, etc, etc), not structures or classes (like the Color structure).

What you could do is create a static class, exposing static read-only
properties/fields which you would set in the static constructor. This would
give you a class with the same semantics as an enumeration.

That is what I thought, but I was hoping for a workaround....

A workaround like this
Thanks for the hint!
