What I do when I want to work with python modules from embedded 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.

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.
With regards,
Patrick
