Thank you, Bradley.
I found a simple sample code on the maillist. Now I could load and execute a
pure python function in a py file in C#.
And a new problem is that the PythonEngine.ImportModule("modulename") method
always return NULL in my case. The modulename.py comsumes a third part ctypes
wrapped library (the Rtree 0.7 python library). It seems the PythonEngine can
not find it, but actually it has been installed to the default path
(C:\Python262\Lib\site-packages\rtree) , and the modulename.py file runs
smoothly under python command line.
I worte a new py file which only contains a function returning the sys.path,
and load it in C#, the sys.path seems OK.
So I don't know what's wrong....
Thanks.

What you are looking to do is "embed" a python interpreter in your .net
project, using pythonnet, and then tell the runtime to execute your python
script.
I have done this in one of my projects. It does work.

Hi there,
I am a freshman and new to python.net.
I have a *.py script which calls a third part python library, and the library
is a ctypes python wrapper of a C++ dll (or say C-based python extension?).
Frist I tried to make it using IronPython. IronPython works well when I load a
pure python *.py (no third part libraries) file and execute it in C# code.
But it failed when I load a *.py which comsumes a thrid part ctypes python
wrapper library mentioned above.
Then I turn to python.net. But I don't know how to load and execute *.py in C#
code using python.net.
Thanks.
