[Python.NET] Could you tell me how to call python from c#?

[SeungWeon Park]

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.
