creating email attachement from stream, always empty.without touching the disk, however, the attachement always turns out to be empty, please help!! I tried attach a existing file and it worked, however I really want to create the attachment on the fly. Here is my code, thanks!!! SmtpClient smtp = new SmtpClient(); smtp.Host = ConfigurationManager.AppSettings["SMTP_HOST"]; smtp.Port = Int32.Parse(ConfigurationManager.AppSettings["SMTP_PORT"]); if (ConfigurationManager.AppSettings["SMTP_AUTH"] == "True") { NetworkCredential cre = new NetworkCredential(ConfigurationManager.AppSettings["SMTP_USERNAME"], ConfigurationManager.AppSettings["SMTP_PASSWORD"]); smtp.Credentials = cre; } MailMessage msg = new MailMessage(); msg.IsBodyHtml = true; msg.To.Add(to); msg.From = new MailAddress(from); msg.Subject = subject; msg.Body = body; ContentType ct = new ContentType(); ct.MediaType = MediaTypeNames.Text.Plain; ct.Name = "InspectionReport.htm"; MemoryStream stream = new MemoryStream(); StreamWriter writer = new StreamWriter(stream); writer.Write(body); Attachment attachement = new Attachment(stream, ct); msg.Attachments.Add(attachement); smtp.Send(msg); writer.Close(); stream.Close(); Hello,
do a writer.Flush() right before calling the Send method..

I commented out the close methods, however same result. This is very annoying. Show quote "Nathan Alden" wrote: > The problem may be threading?

write to the stream, because the size of the stream changed from 0 to somethhing big. Correct me if I am wrong. Show quote "Nathan Alden" wrote: > The problem may be threading?

after you close the writer, do a stream.Seek(0, SeekOrigin.Begin). This will reset the stream position to the beginning of the stream.

It is necessary to seek to the beginning of the stream prior to sending it, and to make sure that that the stream is not closed or disposed until the mail is sent. -- Show quoteHTH, Kevin Spencer Microsoft MVP Bit Player http://unclechutney.blogspot.com Where there's a Will, there's a William.
