Couple of issues. You need to use GetField() not GetProperty() since it's not a property of the form. Second by default labels are protected and the default binding is only to public members. You can either make the label public (bad idea) or alternately specify the binding flags to make ti work. This works:
Label loLabel = (Label) this.GetType().GetField("lblWelcome",BindingFlags.NonPublic | BindingFlags.Public |BindingFlags.Instance).GetValue(this);
