Export PDF then send PDF attachment to email

Question

Hi i am exporting grid view in PDF then I want attach PDF in email, so I am getting error,

Unable to evaluate expression because the code is optimized or a native frame is on top of the call stack.

my code

if (IsEmail)

PdfWriter.GetInstance(pdfDoc, ms);

MemoryStream ms = new MemoryStream();

pdfDoc = new Document(PageSize.A4_LANDSCAPE.Rotate(), 10, 10, 45, 45);

if (IsEmail)

PdfWriter.GetInstance(pdfDoc, ms);

else

PdfWriter.GetInstance(pdfDoc, System.Web.HttpContext.Current.Response.OutputStream);

if (IsEmail)

{                         
ms = new MemoryStream();

byte[] bytes = ms.ToArray();                         
Session["Stream"] = bytes;                         
ms.Write(bytes, 0, bytes.Length);                         
SendEmail(ms, Date, true);                         
ms.Flush();                         
ms.Close();                     
}

Here is the sample code for building the PDF file creating email and attaching the PDF file created. var doc = new Document(); MemoryStream memoryStream = new MemoryStream(); PdfWriter writer = PdfWriter.GetInstance(doc memoryStream); // Build pdf code... doc.Open(); doc.Add(new Paragraph(First Paragraph)); doc.Add(new Paragraph(Second Paragraph)); writer.CloseStream = false; doc.Close(); // Build email memoryStream.Position = 0; MailMessage mm = new MailMessage(username@gmail.com username@gmail.com) { Subject = subject IsBodyHtml = true Body = body }; mm.Attachments.Add(new Attachment(memoryStream filename.pdf)); SmtpClient smtp = new SmtpClient { Host = smtp.gmail.com Port = 587 EnableSsl = true Credentials = new NetworkCredential(username@gmail.com password) }; smtp.Send(mm);
