No way of Invoking a generic method with multiple overload and out/byref parameters #641

Description

@RockHornetz

Environment

  • Pythonnet version: 2.4.0.dev0
  • Python version: 3.6.4
  • Operating System: Windows 7 64

Details

  • Describe what you were trying to get done.

    Invoke a generic method with multiple overload and out parameters

  • What commands did you run to trigger this issue?

//C# SIDE
//...
    public void GetProperty<T>(string propertyName, out T value){...} //<= The one i'm trying to get
    public void GetProperty<T>(string propertyName, out T value, bool asRef){...}
    public void GetProperty<T>(string propertyName, out T value, int index){...}
    public void GetProperty<T>(string propertyName, out T value, int index, bool asRef){...}
    public void GetProperty<T>(PropertyID propertyID, out T value, int index){...}
    public void GetProperty<T>(PropertyID propertyID, out T value, bool asRef){...}
//...
#PYTHON SIDE, What i've tested so far
object.GetProperty[System.Single]('PropertyName', None) #FAIL
object.GetProperty[System.Single]('PropertyName', System.Single(0).GetType()) #FAIL
object.GetProperty[System.Single]('PropertyName', System.Single(0).GetType().MakeByRefType()) #FAIL

object.GetProperty('PropertyName', None) #FAIL
object.GetProperty('PropertyName', System.Single(0).GetType()) #FAIL
object.GetProperty('PropertyName', System.Single(0).GetType().MakeByRefType()) #FAIL

object.GetProperty.Overloads[System.String, System.Single(0).GetType().MakeByRefType()]('PropertyName', None) #FAIL
  • Traceback:
   Traceback (most recent call last):
  File "C:\Users\{USER}\AppData\Local\Programs\Python\Python36\lib\runpy.py", line 193, in _run_module_as_main
    "__main__", mod_spec)
  File "C:\Users\{USER}\AppData\Local\Programs\Python\Python36\lib\runpy.py", line 85, in _run_code
    exec(code, run_globals)
  File "D:/PythonWorkspace/{MODULE}\__main__.py", line 5, in <module>
    test_pythonnet.launchTest()
  File "D:/PythonWorkspace/{MODULE}\test_pythonnet.py", line 45, in launchTest
    test = object.GetProperty[System.Single]('PropertyName', byref)
TypeError: No method matches given arguments

So, i'm at a loss here, do i need to do all the reflection stuff by hand ?
