I tried to post this to the list yesterday but it bounced because of
address issues...hopefully this will work:
If you want to execute a python program from c-sharp you can just use
System.Diagnostics.Process to execute python.exe and you don't need
python for .net.
Python for .net is more appropriate for if you want to execute a python
function or create an instance of a python object and then run methods
and access attributes from your C# program.
The example you linked to is OK, except that he modified the
Python.Runtime.Dll which is not necessary.
If you had a Hello.py with a function called hello Like this:
def hello():
return 'hello'
You could do this in C#:
PythonEngine.Initialize();
PyObject helloModule = PythonEngine.ImportModule("Hello");
String fromPython = helloModule.InvokeMethod("hello", new
PyTuple()).ToString(); PythonEngine.Shutdown();
// now fromPython = "hello"
If your function takes an argument:
def returnArg(arg):
return arg
PythonEngine.Initialize();
PyObject helloModule = PythonEngine.ImportModule("Hello");
String fromPython = helloModule.InvokeMethod("returnArg", new
PyObject[1] {new PyString("Test")}).ToString(); PythonEngine.Shutdown();
// now fromPython = "test"

Subject: Re: [Python.NET] Could you tell me how to call python
from c#?
Hi,
I also would be very interested in seeing some examples to "call
python from c#" using "Python for .NET". I have dug around Google and a
number of forums---I can't find anything except the post from below. I
really hope I'm not missing the obvious somewhere.
IronPython is great but my needs require using a few c++
extensions compiled for CPython (that can't be recompiled).
Also thanks in advance,

Hello, PythonNet!
I'm looking for some sample code to call python from C#.
Actually, I'd like to execute python program(let say 'Hello.py')
from C#
with parameters.
Actually, I'm a newbie at both of languages. So, could you give
sample
source code? I was looking for some guide or source for several
days,
but I couldn't find it. What I've got so far from googling is
http://mail.python.org/pipermail/pythondotnet/2003-November/000037.html,
but I can't understand it and old one.
Thank you in advance.
Seungweon.
