If a class implements an interface explicitly, you will have to "cast" an object to that interface in order to before invoking its methods. Consider the following C# code:

namespaceExample{interfaceIExplicit{intAdd(inta,intb);}publicclassExplicitImpl:IExplicit{intIExplicit.Add(inta,intb){returna+b;}}}

The following example demonstrates how to callAdd:

fromExampleimportIExplicit,ExplicitImplimpl=ExplicitImpl()# Wont work:impl.Add(1,2)# Does work:ifc=IExplicit(impl)ifc.Add(1,2)

Python.NET provides two properties for accessing the object implementing the interface:

• __raw_implementation__ returns the pure CLR object.
• __implementation__ returns the object after first passing it through Python.NETs encoding/marshalling logic.

This is a way to "cast" from an interface to the implementation class.

Here is an example:

importSystemclrVal=System.Int32(100)i=System.IComparable(clrVal)100==i.__implementation__# TrueclrVal==i.__raw_implementation__# True
