Question

I have a Public Class called “ClientConnection”. Inside that class, I have a Public ReadOnly Property called “FileTransfers(ByVal TransferID)”. The property returns an object of the class “FileTransfer”. All methods in FileTransfer are set to public.

VS is able to discover the methods inside the parent class “ClientConnection”. How would I expose the methods inside the sub-class “FileTransfer” that is returned by the property “FileTransfers(ByVal TransferID)”?

Public Class ClientConnection
'irreverent code removed

   Public ReadOnly Property FileTransfers(ByVal TransferID As Integer)
    Get
        Dim obj As FileTransfer = OngoingFileTransfers(TransferID)
        If obj IsNot Nothing Then
            Return obj
        Else
            Return Nothing
        End If
    End Get
   End Property

End Class

Public Class FileTransfer()
  Public Sub StartTransfer() '<--- I need this discoverable in VS from ClientConnection's parent
   'do some stuff
  End Sub
End Class

I understand that this may be difficult to understand. So if you need me to clarify, just ask. Thanks!

I think you just need to indicate what type is returned by your FileTransfers property.

Right now, there is no as clause at the end of the property declaration.

Public ReadOnly Property FileTransfers(ByVal TransferID As Integer) as FileTransfer
 Get
     Dim obj As FileTransfer = OngoingFileTransfers(TransferID)
     If obj IsNot Nothing Then
         Return obj
     Else
         Return Nothing
     End If
 End Get
End Property

This sounds more like a method operation than a property though.
