Multithreading/multiprocessing
by Alan Macdonald May 5, 2025

May 5, 2025

Hello, has anyone successfully used multithreading or multiprocessing with Python.Net? I tried to multi-thread from the .Net side and the Python.Net libraries seem to have issues in the RunScript method. I had to take an implementation off the web of that method because the shipped method doesn’t seem to work. I then had a working multi-processing example from CPython that I tried from Python.Net but it gives an error 'module' object has no attribute 'argv' When trying to create a process pool by executing the line pool = Pool(processes=4) Is it possible to do multithreading or multiprocessing with Python.Net? Thanks, Alan

anonymous types from bug tracker
by Bradley Friedman April 22, 2012

April 22, 2012

Hi all. So I ran into what looks like a bug. Someone else logged it on the sourceforge bug tracker. http://sourceforge.net/tracker/?func=detail&aid=3415722&group_id=162464&ati… I worked around it as the submitter suggests. However, I have two queries. Firstly, is the bug tracker the right place to deal with these things? Or is this mailing list the right place. I ask because the referenced bug doesn't seem to have been looked at all that much. Second, is the suggested work around the correct course of action? Should pythonnet ignore anonymous types?

Using a managed private DLL in python for .NET‏
by Jorn Vanloofsvelt April 7, 2012

April 7, 2012

Dear Brian My question is very short, and I hope that the answer is simple but I have not been able to find an answer on the web. I am using python for .NET, I want to use a private managed DLL. My code looks as follows: import clr from clr import System clr.AddReference("OneWireAPI") That works, however I am unable to get the namespace or its classes. How am I supposed to do this? I figured "from clr import namespace", but that didn't work. I have also tried Assembly.LoadFromFile() Here is an example of usage of this DLL: http://files.maxim-ic.com/sia_bu/softdev/owdocs_400beta2/Docs/OW.NET/OW.NET… Greetings Jorn

Hi, I am trying to call .net dll from python. Is there any instruction that I can follow, since there are some classes in the dll file and I cannot use the traditional ctypes to get the methods in the classes. Could anyone help me with that? Thanks, Xingying
