Re: [Python.NET] Can a python class passed back to .Net

You have to decorate the methods you want to expose to .net with the
clrmethod decorator, e.g.

class MyClass(IInterface):
    @clrmethod(int, [str])
    def overridden_method(self, x):
        return len(x)

The parameters to the clrmethod decorator are the method return type and
argument types. You can expose properties similarly using the clrproperty
decorator.

See runtime/resources/clr.py for details.

Tony
