Environment

  • Pythonnet version: 3.0.2 from pip
  • Python version: Python 3.11.2 (main, Mar 13 2023, 12:18:29) [GCC 12.2.0] on linux
  • Operating System: Debian GNU/Linux 12 (bookworm); Linux localhost 6.1.0-10-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.38-1 (2023-07-14) x86_64 unknown unknown linux
  • .NET Runtime: 8.0.100-preview.3.23178.7 [/home/jorge/.dotnet/sdk]

Details

  • Describe what you were trying to get done.
    I was exploring pythonnet inside Python REPL (by the way it's a very amazing library!) and I tried to use T[].Address(int), but when I called Address using wrong arguments, it crashes the interpreter instead of throwing an exception.
    The same thing happens when trying to use T[].Get and T[].Set.

  • What commands did you run to trigger this issue? If you can provide a
    Minimal, Complete, and Verifiable example
    this will help us understand the issue.

>>> import clr_loader, pythonnet
>>> pythonnet.set_runtime(clr_loader.get_coreclr(runtime_config="/home/jorge/runtimeconfig.json", dotnet_root="/home/jorge/.dotnet"))
>>> pythonnet.load()
>>> import System
>>> array = System.Array[int]((1,))
>>> array.Address()
>>> # runtime being loaded and array created the same way as first example
>>> array.A# press TAB here
  • If there was a crash, please include the traceback here.
