Just a example to show how to use iTextSharp in ASP.ET(no matter asp.net1.1 or asp.net2.0)

        private void Page_Load(object sender, System.EventArgs e)
        {
            // step 1
            // need to write to memory first due to IE wanting
            // to know the length of the pdf beforehand
            MemoryStream m = new MemoryStream();
            Document document = new Document();
            try
            {
                // step 2: we set the ContentType and create an instance of the Writer
                Response.ContentType = "application/pdf";
                PdfWriter writer=PdfWriter.GetInstance(document, m);
                writer.CloseStream=false;

                // step 3
                document.Open();

                // step 4
                document.Add(new Paragraph(DateTime.Now.ToString()));

            document.Close();

            // step 6: Write pdf bytes to outputstream
            Response.OutputStream.Write(m.GetBuffer(), 0, m.GetBuffer().Length);
