[Ironpython-users] How to call parameterless overload of generic method?

[Markus Schaber]

Hi,

The attached C# file demonstrates a small problem we currently encountered using IronPython 2.7.4:

We have a C# method which has two overloads - one is parameterless, and the other one has a single out parameter.

For non-generic methods, it is possible to call both variants when calling with and without clr.Reference, but this does not work for generic methods.

When trying to call the parameterless generic method directly, the following exception appears:

Microsoft.Scripting.ArgumentTypeException was unhandled
  HResult=-2146233088
  Message=Multiple targets could match: Method(), Method()
  Source=Microsoft.Dynamic
  StackTrace:
[snipped]

The workaround is to use the .Overloads[] syntax:

print instance.Method[str].Overloads[()]()


Btw, trying "print instance.Method[str].Overloads[int]()" leads to the following funny ArgumentTypeException: "Method() takes at least 2147483647 arguments (0 given)"
