String Representation of an Enum #575

Environment

  • Pythonnet version: All
  • Python version: 2.7
  • Operating System: Mono

Details

  • Print string name of an enum from python.
   // in C#
   enum NamePrinting {
       Test,
       Name
   }

   // in python:
   self.A = "A" + str(NamePrinting.Test)
   print A
   // A1 not "ATest" like in C#.

Is it possible to get the text string name instead of the integer?

@jaredbroad the problem here is that C# enum is converted to its value (int) before you can do anything with this enum in Python. Here are possible fixes for similar issue, that I suggested before:

#174 (comment)

Current str() representation of .NET enums is sub-optimal per se (strong .NET typing information is lost) and also is an incompatibility with IronPython.

@denfromufa suggested several approaches to support better enum str() representation, including

  • special case enums in overloading method selection to allow inter-operability with integer types.

What about using IntEnum? According to the docs, special casing enums may not be at all required as IntEnums are already ints.

@aparamon this would work only in Python 3 which is ok. This contribution is welcome!

Enums are enums in .NET - this is a very weird decision to replace with integers. Are we back to the 'error code days' ?

Contributions are welcome. Python.NET is a very old library, dating back to Python 2.2 (I think), IntEnum etc. didn't exist back then.

I tried to replicate this issue because I'd like to contribute but this seems to work for .net versions greater than 4.6

This was indeed implemented by @lostmsu in #1392 (so it works with builds from the current master, independent of the .NET version).
