Implementing 2 Interfaces with 'Same Name' Properties

Question

This seems like a reasonable (and maybe simple?) scenario, but how would you do the following:

Lets say I have 2 interfaces:

Interface ISimpleInterfa         


        

Answer 1

The Implements keyword in VB.NET makes this easy:

Public Interface ISimpleInterface
  ReadOnly Property ErrorMsg() As String
End Interface

Friend Interface IExtendedInterface
  Property ErrorMsg() As String
  Property SomeOtherProperty() As String
End Interface

Public Class Foo
  Implements ISimpleInterface, IExtendedInterface
  Private other As String
  Private msg As String

  Public Property ErrorMsgEx() As String Implements IExtendedInterface.ErrorMsg
    Get
      Return msg
    End Get
    Set(ByVal value As String)
      msg = value
    End Set
  End Property

  Public Property SomeOtherPropertyEx() As String Implements IExtendedInterface.SomeOtherProperty
    Get
      Return other
    End Get
    Set(ByVal value As String)
      other = value
    End Set
  End Property

  Public ReadOnly Property ErrorMsg() As String Implements ISimpleInterface.ErrorMsg
    Get
      Return msg
    End Get
  End Property
End Class
