I really do not know how you can achieve that line to be understood by the designer. Here is what I have:

        Public oDirectory As Collection = New Collection

And, then, in my client class:

        Dim result = loFTP.oDirectory.OfType(Of Object())().OrderByDescending(Function(x) x(0))

And the designer says:

"'OfType' is not a member of 'Microsoft.VisualBasic.Collection'."
