My aspx page contains text boxes. i want the pdf file to have all the values entered in the text box. I was able to convert to pdf using iTextSharp but the text box values are not getting saved. Let me know if you have any approach to do this.
Here is the code am using.

protected void SendMail()
        {
            var userName = "[e-mail]";
           
            var toAddress = YourEmail.Text.ToString();
            
            const string Password = "Mypassword123#";
          
            string subject = YourSubject.Text.ToString();
            string body = "From: " + YourName.Text + "\n";
            body += "Email: " + YourEmail.Text + "\n";
            body += "Subject: " + YourSubject.Text + "\n";
            body += "Question: \n" + Comments.Text + "\n";
        
           
            var smtp = new System.Net.Mail.SmtpClient();
            {
                smtp.Host = "10.238.52.200";
                smtp.Port = 25;
                smtp.EnableSsl = false;
                smtp.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network;
                smtp.Credentials = new NetworkCredential(userName, Password);
                smtp.Timeout = 20000;
            }
            smtp.Send(userName, toAddress, subject, body);
        }
         protected void Button1_Click(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); 
           
            Response.Write(pdfDoc);
           
             try
            {
                 SendMail();
               
                DisplayMessage.Text = "Your Comments after sending the mail";
                DisplayMessage.Visible = true;
                YourSubject.Text = "";
                YourEmail.Text = "";
                YourName.Text = "";
                Comments.Text = "";
                pdfDoc.Close();
                Response.End();
            }
            catch (Exception) { }
        }

推荐答案

嗨 不要使用Response.OutputStream，而是使用memoryStream，因为在Response.End()
关闭输出流，并处理在输出流中创建的pdf.

Hi Instead of using Response.OutputStream use memoryStream because on Response.End()
the output stream is closed and created pdf in output stream is disposed.
