Importing external module in IronPython

Question

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 ;)

Answer 1

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.
