[RESOLVED] Hide Base Methods In An Inherited Class

I'm trying to hide base methods in an inherited class, and I am using a method where a wrapper is used to return an interface of methods that are seen, like so:

vb.net Code:

Public Class MyWrapper
 
    Private _MyStringList As MyStringList
 
    Public Sub New()
        Me._MyStringList = New MyStringList
    End Sub
 
    Private _List As IMyListFunctions
    Public Property List() As IMyListFunctions
        Get
            Return _List
        End Get
        Set(ByVal value As IMyListFunctions)
            _List = value
        End Set
    End Property
 
    Private Class MyStringList
        Inherits List(Of String)
        Implements IMyListFunctions
 
        Public Overloads Sub Add(ByVal item As String) Implements IMyListFunctions.Add
            MyBase.Add(item)
        End Sub
 
        Public Overloads Function Contains(ByVal item As String) As Boolean Implements IMyListFunctions.Contains
            Return MyBase.Contains(item)
        End Function
 
    End Class
 
    Public Interface IMyListFunctions
        Sub Add(ByVal item As String) 'Allow Add
        Function Contains(ByVal item As String) As Boolean 'Allow Contains
    End Interface
 
End Class

And what I am basically wondering is if there is an easier way to do this. Is there some sort of Compile attribute I can apply instead?

EDIT: The best way to do this (Microsoft does this) is to use these Attributes:

vb.net Code:

<System.ComponentModel.EditorBrowsable(System.ComponentModel.EditorBrowsableState.Never), System.ComponentModel.DesignerSerializationVisibility(System.ComponentModel.DesignerSerializationVisibility.Hidden)> _
APropertyOrMethod

Overtop of a Method or Property, then if they are called throw NotSupportedExceptions.
