PDFsharp & MigraDoc Foundation

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?

Thanks SO much for your time!!!

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

Of course not.

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 .
