PC SDK: documentation code snippet language confirmation

I was going through PC SDK documentation, and found these code snippets

Private Sub rd_ValueChanged(ByVal sender As Object, ByVal e As DataValueChangedEventArgs)
Me.Invoke(New EventHandler(UpdateGUI), sender, e)
End Sub

Private Sub UpdateGUI(ByVal sender As Object, ByVal e As System.EventArgs)
Dim tool1 As ToolData = DirectCast(Me.rd.Value, ToolData)
Me.label1.Text = tool1.Tframe.Trans.ToString()
End Sub

It took me a few minutes of trying to understand the code, until I realised that they were probably mistakenly labelled as C#. I thought they look more like VB.net instead.

Just to confirm.
