[Python.NET] Accessing class interface with private methods

Actually, there is a way to access private members in C#.
You can use System.Reflection to modify access directives.

Since you can't access private members from Python .net, you could write a
seperate C# module that unhides private members and exposes them as
You could then call those public methods from Python for .NET.

Cumbersome, but should work.

Kind regards, Tijs

This is not supported. You can't access private methods in C# or VB.NET
either, so why should Python.NET be able to access them? But one thing to
note is that you CAN access protected methods directly in Pyhon.NET (you
don't have to make a subclass to use a protected method).

I am having trouble using Python.NET in accessing class interface methods
that are declared private.  As an example,

Public Interface Iface
    Property Func() As Boolean
End Interface

Public Class Foo
    Implements Iface

    Private Function Func() As Boolean
        Return True
    End Function

    Public ReadOnly Property IFACE() As Iface
            Return Me
        End Get
    End Property
End Class

Then using Python 2.5 with Python.Net 2.0 alpha 2,  I cannot access the
method.  Is this supported?

import clr
import Foo
f =  Foo()
f.IFACE              # OK
f.IFACE.Func()    # results in Attribute error
