Importing external module in IronPython

import, ironpython, python

Solution

Before compiling a script with the PythonEngine, I add the script's directory to the engine's search path. This is what I do in the C# code:

string dir = Path.GetDirectoryName(scriptPath);                       
ICollection<string> paths = engine.GetSearchPaths();

if (!String.IsNullOrWhitespace(dir))
{
    paths.Add(dir);
}
else
{
    paths.Add(Environment.CurrentDirectory);
}
engine.SetSearchPaths(paths);

Now if the libraries are in the directory where the scripts, which you are executing, reside they will be importable.

Problem

I'm currently working on an application written in C#, which I'm embedding IronPython in. I generally have no problems about it, but there's one thing that I don't know how to deal with. I want to import an external module into the script. How can I do that? Simple `import ext_lib` doesn't work. Should I add a path to the lib to `sys.path`? Maybe it is possible to copy the lib's .py file into app directory and import from there? EDIT: I finally chosen another solution - compiled my script with `py2exe` and I'm just running it from main C# app with `Process` (without using IronPython). Anyway, thanks for help ;)
