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).

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 specified as
being for IP1:

Thank you again.

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 :-).
