Hello Forum,

I tried to export an invoice on my web form to PDF and send PDF file as attachment to mail but I got an error. The screenshot below shows the error I got.

    protected void Button1_Click(object sender, EventArgs e)
    {
        using (StringWriter sw = new StringWriter())
        {
            using (HtmlTextWriter hw = new HtmlTextWriter(sw))
            {
                this.Page.RenderControl(hw);
                StringReader sr = new StringReader(sw.ToString());
                Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 10f, 0f);
                HTMLWorker htmlparser = new HTMLWorker(pdfDoc);
                using (MemoryStream memoryStream = new MemoryStream())
                {
                    PdfWriter.GetInstance(pdfDoc, memoryStream);
                    pdfDoc.Open();
                    htmlparser.Parse(sr);
                    pdfDoc.Close();
                    byte[] bytes = memoryStream.ToArray();
                    memoryStream.Close();

                    MailMessage mm = new MailMessage("georgeakpan13@gmail.com", "ukosimons@gmail.com");
                    mm.Subject = "GridView Exported PDF";
                    mm.Body = "Invoice Exported PDF Attachment";
                    mm.Attachments.Add(new Attachment(new MemoryStream(bytes), "GridViewPDF.pdf"));
                    mm.IsBodyHtml = true;
                    SmtpClient smtp = new SmtpClient();
                    smtp.Host = "smtp.gmail.com";
                    smtp.EnableSsl = true;
                    System.Net.NetworkCredential NetworkCred = new System.Net.NetworkCredential();
                    NetworkCred.UserName = "georgeakpan13@gmail.com";
                    NetworkCred.Password = "etekamba233#";
                    smtp.UseDefaultCredentials = true;
                    smtp.Credentials = NetworkCred;
                    smtp.Port = 587;
                    smtp.Send(mm);
                }
            }
        }
    }

I set my image with this

<asp:Image ID="Image1" runat="server" ImageUrl="http://localhost:49893/Default.aspx/images/qr_code_red.png" Width="80px" Height="80px" />

I am using local server; Is this not the complete image Url ?

the error still shows after. Please is there no other way or a clear understaning on the issue with explanation on how solve this ?
