WebException was unhandled by user code

Hi,

I am trying to export webpage to pdf and I get the below error. Not sure what is causing the error.

Could not find a part of the path 'C:\Program Files\Common Files\Microsoft Shared\DevServer\10.0\Images\Logo.PNG'.

 public override void VerifyRenderingInServerForm(Control control)
  {
  }
  protected void ExporttoPDF(object sender, EventArgs e)
  {
  Response.ContentType = "application/pdf";
  Response.AddHeader("content-disposition", "attachment;filename=TestPage.pdf");
  Response.Cache.SetCacheability(HttpCacheability.NoCache);
  StringWriter sw = new StringWriter();
  HtmlTextWriter hw = new HtmlTextWriter(sw);
  this.Page.RenderControl(hw);
  StringReader sr = new StringReader(sw.ToString());
  Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 100f, 0f);
  HTMLWorker htmlparser = new HTMLWorker(pdfDoc);
  PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
  pdfDoc.Open();
   htmlparser.Parse(sr);
  pdfDoc.Close();
  Response.Write(pdfDoc);
  Response.End();
  }
I get the error at the highlighted line.
