I am trying to email a PDF file I create. Here is my current code. It sends the file, but the file has nothing in it. When I open it, the error says: "Adobe Reader could not open because it is either not a supported file type or because the file has been damaged (for example, it was sent as an email attachment and wasn't correctly decoded)."

private static void SendEmail(PdfDocument pDoc)
{
try
{
MailAddress SendFrom = new MailAddress("brendalisalowe@gmail.com", "Brenda Hatch");
MailAddress SendTo = new MailAddress("brendalisalowe@hotmail.com", "Recepient name");

MailMessage MyMessage = new MailMessage(SendFrom, SendTo);
MyMessage.Subject = "HUD Instructions";
MyMessage.Body = "Testing...";

//http://stackoverflow.com/questions/1073277/pdfsharp-save-to-memorystream
Document doc = new Document();
DocumentRenderer renderer = new DocumentRenderer(doc);
PdfDocumentRenderer pdfRenderer = new PdfDocumentRenderer();
pdfRenderer.PdfDocument = pDoc;
pdfRenderer.DocumentRenderer = renderer;
using (MemoryStream ms = new MemoryStream())
{
pdfRenderer.Save(ms, false);
byte[] buffer = new byte[ms.Length];
ms.Seek(0, SeekOrigin.Begin);
ms.Flush();
ms.Read(buffer, 0, (int)ms.Length);
//ContentType ct = new ContentType(MediaTypeNames.Application.Pdf);
//MyMessage.Attachments.Add(new Attachment(ms, ct));
MyMessage.Attachments.Add(new Attachment(ms, "HUDInstructions.pdf", "application/pdf"));
SmtpClient client = new SmtpClient("smtp.gmail.com", 587);
client.EnableSsl = true;
NetworkCredential myCreds = new NetworkCredential("asdfasdf@gmail.com", "asdfasdfadsf", "");
client.Credentials = myCreds;
client.Send(MyMessage);
}


//litStatus.Text = "Message Sent";
}
catch (Exception ex)
{
//litStatus.Text = ex.ToString();
}

When I open the file like this instead of trying to email it, it works great!!!

PdfDocument document = (PdfDocument)Session["Document"];

// Send PDF to browser
MemoryStream stream = new MemoryStream();
document.Save(stream, false);
Response.Clear();
Response.ContentType = "application/pdf";
Response.AddHeader("content-length", stream.Length.ToString());
Response.BinaryWrite(stream.ToArray());
Response.Flush();
stream.Close();
Response.End();


Any ideas?

Thanks!!!

Should I try to keep continuing down this road? Or do I need to try another way of doing this?

That's not your email credentials in your example is it?

In the working sample you only use 2 lines of code to save the PDF to a MemoryStream:
// Send PDF to browser
MemoryStream stream = new MemoryStream();
document.Save(stream, false);

In the case that does not work, you use 20 lines of code from stackoverflow.com to achieve the same task.

I suggest using the 2-line-version to get a memory stream. I don't understand which problem shall be avoided by the 20-line-version.
The post on stackoverflow.com says there is an issue with document.Save - I never heard of that, but I'll check it eventually.

Use the two line version, but set the stream position to 0 before adding it to the attatchment

document.Save(stream, false);
stream.Position = 0;
Attachment att = new Attachment(stream, filename, System.Net.Mime.MediaTypeNames.Application.Pdf);

Thanks a million mmeliska!

Using:
Stream.Position = 0;

before constructing the attachment object as proposed solved this problem for me :).

Grtz,
Bart
