To correct this error

  • Cast the value to the base interface that you want to use; for example:

    Interface Left
        Sub MySub()
    End Interface
    
    Interface Right
        Sub MySub()
    End Interface
    
    Interface LeftRight
        Inherits Left, Right
    End Interface
    
    Module test
        Sub Main()
            Dim x As LeftRight
            ' x.MySub()  'x is ambiguous.
            CType(x, Left).MySub() ' Cast to base type.
            CType(x, Right).MySub() ' Call the other base type.
        End Sub
    End Module
