Am using itextsharp. I got this error "The specified path, file name, or both are too long. The fully qualified file name must be less than 260 characters, and the directory name must be less than 248 characters.". Please help me to over come this.

Code Snippet:

{
    Response.ContentType = "application/pdf";
    Response.AddHeader("content-disposition", "attachment;filename=" + HttpContext.Current.Session["StudentID"].ToString() + ".pdf");
    Response.Cache.SetCacheability(HttpCacheability.NoCache);
    StringWriter sw = new StringWriter();
    HtmlTextWriter hw = new HtmlTextWriter(sw);
    frmPrint.RenderControl(hw);
    StringReader sr = new StringReader(sw.ToString());
    Document pdfDoc = new Document(PageSize.A3, 0f, 0f, 0f, 0f);
    HTMLWorker htmlparser = new HTMLWorker(pdfDoc);
    PdfWriter writer;
    PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
