Well, you learn something every day. I just discovered that .NET enumerations can have duplicate values. I personally think this is little dangerous as the primary use of enumerations is to provide discrete numerical values for text based names, but I can image there are edge cases in which it comes in handy. The same is true for negative values, which I did know about. Sometimes it is useful to just cast an enum value to the final value you want instead of starting at zero and doing the subtraction every time.
