"TypeError: No method matches given arguments" error for a virtual method with a template parameter #1522
Description
Environment
- Pythonnet version: 3.0.0.dev1
- Python version: 3.9.6 (also tried on 3.7)
- Operating System: Ubuntu 20.04
- .NET Runtime: mono-devel (Mono JIT compiler version 6.8.0.105)
- Open XML SDK 2.13.0 (from https://www.nuget.org/packages/DocumentFormat.OpenXml/)
Details
Trying to re-implement example from here using Python.
Everything works fine except this line of code:
slideMasterPart1.AddPart(slideLayoutPart1, "rId1");There are two definitions of AddPart:
public virtual T AddPart<T>(T part) where T : OpenXmlPart
public virtual T AddPart<T>(T part, string id) where T : OpenXmlPart slideMasterPart1.AddPart.Overloads output:
T AddPart[T](T)
T AddPart[T](T, System.String)
What works:
slideMasterPart1.AddPart(slideLayoutPart1)
slideMasterPart1.AddPart[SlideLayoutPart](slideLayoutPart1)What doesn't work:
slideMasterPart1.AddPart(slideLayoutPart1, "rId1")
slideMasterPart1.AddPart(slideLayoutPart1, System.String("rId1"))
slideMasterPart1.AddPart[SlideLayoutPart](slideLayoutPart1, "rId1")Error:

TypeError: No method matches given arguments for AddPart: (<class 'DocumentFormat.OpenXml.Packaging.SlideLayoutPart'>, <class 'str'>)
mcve:
import clr
clr.AddReference('DocumentFormat.OpenXml')
from DocumentFormat.OpenXml.Packaging import (
SlideLayoutPart,
SlideMasterPart,
)
slideLayoutPart1: SlideLayoutPart = SlideLayoutPart()
slideMasterPart1: SlideMasterPart = SlideMasterPart()
slideMasterPart1.AddPart(slideLayoutPart1) # this works OK
slideMasterPart1.AddPart(slideLayoutPart1, "rId1") # this raises a runtime exceptionSo it's only when the second (string) parameter is provided, the first can't be converted. Looks like a pythonnet issue.
