simple google search revealed this example from Bryan Lloyd for casting to interface:

Let us know if it works:

> from mynamespace import Foo, Iface
> 
> inst = Foo() # create an instance
> 
> wrapped = Iface(inst) # 'cast' to the interface
> 
> wrapped.Func() # should now work

Hi,

 

The Python win32com module for accessing COM objects provides a method CastTo for casting an object to a different interface.

Similarly, in my application, I have to cast an object to another .Net interface. Does  Python.Net provide such a method or can you describe a way of doing the casting using C# libraries?

 

Here is a small example:

I have an object of type ILDERow and want to cast it to ISurfaceCoordinateBreak. Using win32com this can be done in the following way:

from win32com.client import CastTo

cbSurface = CastTo(surface, "ISurfaceCoordinateBreak")

 

Thank you very much!

 

Best regards,

Matthias
