Using C# Assemblies From Python Via Pythonnet

I am using Windows 7, 64-bit. I have managed to download and install pythonnet, so import clr clr.AddReference('System.Windows.Forms') from System.Windows.Forms import Form works

Solution 1:

Just to provide another method:

import sys
sys.path.append("C:\Path\to\your\assemblies")

clr.AddReference('MyAssembly')
from MyAssembly import MyClass

MyClass.does_something()

This assumes that in the C:\Path\to\your\assemblies folder you have a MyAssembly.dll file.

So the 'trick' is that you have to add your assemblies folder to the sys.path before clr.AddReference.

Solution 2:

From what I gather you are trying to load an external assembly in Python.Net, I have done little work with that library. You should consider using IronPython instead but using Python.Net you could load the assembly via .Net's reflection like this

>>> import clr
>>> from System.Reflection import Assembly
>>> dll1 = Assembly.LoadFile("C:\Python\Python27-32\Lib\site-packages\Python.Runtime.dll")
>>> clr.Python.Runtime
<module 'Python.Runtime'>
>>> clr.Python.Runtime.PythonEngine
<class'Python.Runtime.PythonEngine'>
