Running CPython functions from C#

Question

I'm working on a project where I need to be able to run a python function that depends on SciPy/NumPy. Due to this being an add-on to a project already in progress, using IronPython would not be an option.

Additional info:

• Python.NET seemed to be a good fit, but I was unable to get the return value from RunString() (it would only return NULL).
• Passing arguments and catching the return value (a tuple) is necessary.
• The function is in a statistical package that was created by a support group for the team, so modification of that would also not be possible.

I'm at quite a loss for what to do. Any hints in the right direction are appreciated. Thanks for any help you can give!

I understand that this may be quite vague, but I cannot give explicit details to the project. If any clarification is needed please let me know and I'll do my best!

I guess you could write a DLL that uses the CPython API to expose the function, then call it in C#? It's possible to embed the Python interpreter; although I've never done this personally, I guess it would be useful: http://docs.python.org/extending/embedding.html
