I'm a bit late with responding to this as I was kinda busy. I used the
code that was given Stephen and it seems to run properly without
throwing exceptions. However, I created a little autoexec.py file with a
simple function in it with 2 parameters.
The main problem here is: How do I call the function through the scope?
I used engine.CreateScope() to create myself a new scope, but from there
on, I'm basically lost(again). What I basically want to do, is call my
function 'add' with 2 parameters(say, 10 and 15). The modules itself are
loaded into a ScriptSource.
Thanks,
Patrick

IronPython is set the IronPython search path with the path of the
module to load then create and execute a small python script that
loads the main python modules into the current scope.
string moduleName = Path.GetFileName(modulePath);
string path = Path.GetDirectoryName(modulePath);
ICollection<string> paths = _pythonEngine.GetSearchPaths();
if (!paths.Contains(path))
{
paths.Add(path);
_pythonEngine.SetSearchPaths(paths);
}
string modInvoke = String.Format("import {0}\nfrom {0} import *\n",
moduleName);
ScriptSource source =
_pythonEngine.CreateScriptSourceFromString(modInvoke,
Microsoft.Scripting.SourceCodeKind.Statements);
Where modulePath is the full path to the python module or package to load.
I can then invoke methods or access attributes using the IronPython
scope. In this way, I can interact with the python modules for as
long as necessary before closing down the scope/engine.

functions from C#
You can read all yours file scripts, then using StringBuilder to
combine then and call CreateScriptSourceFromString()
Then you can call your functions within the combined scripts normally.
Pretty much you are creating a giant source code on the fly.

I'm currently attempting to embed the IronPython 2 runtimes into an
existing application written in C#. However, I find the amount of
documentation lacking on what I'm trying to do. I currently have a
proof-of-concept version which uses Lua and LuaInterface, but the
people who have to write the scripts dislike Lua(Well, more hate it
with a passion) and would love to see this working with Python.
My host application is a networked application that must trigger
certain scripts functions on events generated by the connected
clients. The idea is that when my application starts, it will load the
IronPython script environment, launches an 'autoexec.py' which will
load various other scripts files and do some housekeeping. Once this
all is completed, it will start listening to incoming connections.
However, in various scenarios, the application has to trigger scripted
functions when data is received from a client. Which script function
is called is different per client and per event. I have events for
connecting, logging on, disconnecting and a set of data specific
events after receiving data. This highly depends on the received packets.
My question here is: How do I embed IronPython in such a fashion that
I can load my scripts and then trigger various functions within that?
I've seen many examples that just call CreateScriptSourceFromString()
or File each time in which just 1 piece of code is implemented. This
is not suitable for the needs here because the scripted systems can
become quite complex.

Patrick
