Fully Qualified Interface Member Names

Interface members are sometimes referred to by their fully qualified name. The fully qualified name of an interface member consists of the interface name, followed by a dot, followed by the member name. When an interface is part of a namespace, the fully qualified name of an interface member includes the namespace name.

Example

Interface IUserInterface1
    Sub Test();
End Interface;

Interface IUserInterface2
    Sub Test();
End Interface;

Class UserObject: IUserInterface1, IUserInterface2
    Sub IUserInterface1.Test();
    Begin
        //Method implementation
    End Sub;

    Sub IUserInterface2.Test();
    Begin
        //Method implementation
    End Sub;
End Class;

Sub Test();
Var
    Obj: UserObject = New UserObject();
Begin
    //Invoke two different Test methods
    (Obj As IUserInterface1).Test();
    (Obj As IUserInterface2).Test();
End Sub;
