ms = new MemoryStream();

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

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("[email protected]", "[email protected]")

{

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("[email protected]", "password")

};

smtp.Send(mm);
