python.net

问题 I have to rewrite the following VB code that is subscribing to a delegate (event), into python, using python.net.

Also the process explorer shows the dll still loaded. More

问题 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 fine. I have also downloaded and compiled/run a C# application which creates lots of assemblies. The application in question is ARDrone-Control-.NET. How can I use the generated DLL files from Python (and not just the built-in C# classes). Since I have never used C# (which is why I want to use the library from Python

问题 I want to use a method of a static class. This is my C# code: namespace SomeNamepace { public struct SomeStruct { .... } public static class SomeClass { public static double SomeMethod { .... } } If it was a "normal" class I could use SomeMethod like lib = clr.AddReference('c:\\Test\Module.dll') from System import Type type1 = lib.GetType('SomeNamespace.SomeClass') constructor1 = type1.GetConstructor(Type.EmptyTypes) my_instance = constructor1.Invoke([]) my_instance.SomeMethod() But when
