Good point! I forgot that I was having the *.py files in a subdirectory.
Is it also possible to set the 'current' directory for the engine?
For instance I would like to have the engine living in a subfolder of
my project and then all path's would be relative to this subfolder.
Windows only has a concept of a current directory per process (actually
technically per drive per process but never mind). Changing your current
directory in your host app will change it for all contained engines...
Any of your Python scripts changing the current directory will also
change it for the host app.
For Python scripts in general (not just IronPython) it is much better to
do relative path resolution yourself, relative to the current __file__
or sys.executable (which you are likely to need to set in a hosted
environment).
All the best,
Michael
thank you,

Hello,
I'm digging out this thread again.
I'm trying to run python scripts from C# using the DLR.
Simple examples work, namely if I have just one function in
one python file.
How does it work when one python file imports from another
python file? I get "No module named x" ImportExceptions when
trying to compile these python files.
If you're running them from '.py' source files then you aren't
compiling them - you're just executing them from an embedded
environment.
The import machinery should work exactly the same as for CPython,
but you may need to setup the initial sys.path depending on how
you are executing the scripts.
You probably need to use the engine.SetSearchPaths method passing
in an array with the path to the directory containing the top
level Python file (adding any other directories that you need to
be able to import from).
HTH

I compile the main-file with 'CreateScriptSourceFromFile'.
May be I am using the wrong approach in general. What I have
is a bunch of python files that I used with CPython directly
so far. Now I want to extend my program with C# (since
database handling is much more convenient there) and I want to
use the python files that I already have.
What is the best approach for this scenario?
Thanks for any kind of hint.

Ok, Thank you.
Does anyone know where could I find an IronPython Assembly
documentation and/or up to date tutorials ?
These tutorials are up to date - except for the one

I believe this was valid for a long-ago alpha. For
the 2.0
release, you'll want to create an engine by saying
engine = Python.CreateEngine()

Hi,
I want to use IronPython function through C#. To
do It, I
found a tutorial at
http://www.ironpython.info/index.php/Hosting_IronPython_2.
But the code does not seem to be updated for
IronPython
2.0.
the code is :
using System;
using IronPython.Hosting;
using IronPython.Runtime;
using Microsoft.Scripting;
using Microsoft.Scripting.Hosting;
namespace EmbeddedCalculator
{
public class Engine
{
private ScriptEngine engine;
public Engine()
{
engine = PythonEngine.CurrentEngine;
}
public string calculate(string input)
{
try
{
ScriptSource source =
engine.CreateScriptSourceFromString(input, "py");
return source.Execute().ToString();
}
catch
{
return "Error";
}
}
}
}
// End of code
When I try to compile it in visual studio, the
compiler
could
not find the name "PythonEngine". I have added
all the
references to
the needed libraries. So, what am I missing ?
Thank you :-).
