vb.net - 完全修飾型名からの GetType が機能しない

Question

Public Sub New(ByVal oldC As Control)
    Dim FQTN As String = oldC.GetType.FullName
    Dim t As Type = Type.GetType(FQTN)
    Dim newC As Object = Activator.CreateInstance(t)
End Sub

FQTNは正しいタイプ名を返していますがt、Nothing. たとえば、FQTN = System.Windows.Forms.Panel.
