Similar classes with different signatures

I have two classes:

    Public Class Subscribing

    Private _subscribingObjects As IList(Of String)

    Public Sub Add(ByVal obj As SubscribeObject)
        '...code...'
    End Sub

    Public Sub Remove(ByVal index As Integer)
        '...code...'
    End Sub

    End Class

    Public Class Providing

    Private _providingObjects As IList(Of String)

    Public Sub Add(ByVal obj As ProvideObject)
        '...code...'
    End Sub

    Public Sub Remove(ByVal index As Integer)
        '...code...'
    End Sub

    End Class

Is there a more elegant way to add do this? One class would suffice, but since the Add methods have different arguments, then one really wouldn't work.

Any help would be appreciated.

this?

Public Class SubscribingProviding(Of t)

Private _subscribingObjects As IList(Of String)

Public Sub Add(ByVal obj As t)
    '...code...'
End Sub

Public Sub Remove(ByVal index As Integer)
    '...code...'
End Sub

End Class
