C# / IronPython Interop with shared C# Class Library
- by Adam Haile
I'm trying to use IronPython as an intermediary between a C# GUI and some C# libraries, so that it can be scripted post compile time.
I have a Class library DLL that is used by both the GUI and the python and is something along the lines of this:
namespace MyLib
{
public class MyClass
{
public string Name { get; set; }
public MyClass(string name)
{
this.Name = name;
}
}
}
The IronPython code is as follows:
import clr
clr.AddReferenceToFile(r"MyLib.dll")
from MyLib import MyClass
ReturnObject = MyClass("Test")
Then, in C# I would call it as follows:
ScriptEngine engine = Python.CreateEngine();
ScriptScope scope = null;
scope = engine.CreateScope();
ScriptSource source = engine.CreateScriptSourceFromFile("Script.py");
source.Execute(scope);
MyClass mc = scope.GetVariable<MyClass>("ReturnObject ")
When I call this last bit of code, source.Execute(scope) runs returns successfully, but when I try the GetVariable call, it throw the following exception
Microsoft.Scripting.ArgumentTypeException: expected MyClass , got MyClass
So, you can see that the class names are exactly the same, but for some reason it thinks they are different.
The DLL is in a different directory than the .py file (I just didn't bother to write out all the path setup stuff), could it be that there is an issue with the interpreter for IronPython seeing these objects as difference because it's somehow seeing them as being in a different context or scope?
