Enum.GetNames() results in unexpected order with negative enum constants

Question

I have the following enum definition (in C#):

public enum ELogLevel
{
    General = -1,  // Should only be used in drop-down box in Merlinia Administrator lo         


        

Answer 1

This is a known bug with both GetNames() and GetValues() that was reported here, but ended up getting closed as won't fix:

Yes, this method indeed has a bug where it returns the array of enum values sorted as unsigned-types (-2 is 0xFFFFFFFE and -1 is 0xFFFFFFFF in two's complement, that's why they are showing up at the end of the list) instead of returning values sorted by their signed-types.

Unfortunately, we cannot change the sort order of GetValues because we will break all existing .NET programs that have been written to depend on the current sorting behavior [...]

Looks like you'll have to reorder the values yourself.
