Calling Python from .NET via C++ bridge

问题 Once per a couple of months I google for "Call Python from .NET" when I am too tired to reinvent/port stuff and find some cool code in Python. The two popular solutions are to start an external process or to use IronPython IronPython is not an option for me since the reason I might want to use Python is usually some libraries that depend on NumPy/ScyPy. Recently I started to learn the very basics of C++ and have found that one could embed Python in C++, and have found an article with an

How to Interop to C++ with Namespace

由 浪尽此生 提交于 2019-12-21 20:26:12
问题 I have a C++ function, that I want to expose to C# for consumption. The catch is that the C++ code declaration is wrapped in namespace : namespace OhYeahNameSpace { extern "C" __declspec(dllexport) void Dummy(); } My question is, how to define the corresponding C# structure? I believe that C# code must be made aware of the existence of OhYeahNameSpace , am I right? Edit: I think a lot of people misunderstand my point ( no thanks due to a typo in my original example; fixed). I am asking about

问题 I am trying to pass a double array (its actually a std::vector, but converted at transfer) from a c++ dll into a c# script (unity).

For a little more background this array is part of a control for a GUI, c++ creates

How do I implement the dispose pattern in c# when wrapping an Interop COM Object?

由 China☆狼群 提交于 2019-12-21 17:06:54
问题 My class contains an object from Interop and calls a method on it which causes it to alloc stuff. It also exposes a method to free that stuff, so I expect I should call this in Dispose(): class MyClass : IDisposable { private DllName.ComClassName comInstance; void SomeMethod() { comInstance = new DllName.ComClassName(); comInstance.AllocStuff(); } public void Dispose() { comInstance.FreeThatStuff(); } } Now, I should expand all that to follow the Dispose pattern. I have no other disposable or
