[IronPython] .NET Exception to Python Exception conversion

[Dino Viehland]

If the exception was raised in Python then you should be able to do:

print event.Exception.Data['PythonExceptionInfo']

which will contain the Python exception object, not that I'm sure you can format that one much better.

What you probably want to do is call PythonEngine.FormatException(event.Exception), for example:

from IronPython.Hosting import PythonEngine

x = PythonEngine()
print x.FormatException(event.Exception)

If you're hosting IronPython then you can use your previously instantiated PythonEngine instead of newing one up just to format an exception.

Subject: [IronPython] .NET Exception to Python Exception conversion

Hello,

I'm catching exceptions raised in my winforms thread using

            def exceptionHandler(sender, event):
                print event.Exception

            Application.ThreadException += ThreadExceptionEventHandler(exceptionHandler)
            Application.SetUnhandledExceptionMode(UnhandledExceptionMode.CatchException)

However the exception I get, contains the long, unintuitive stack trace. How can I convert it to a nice Python exception ?

Regards,
Laurent Debacker.
