Can somebody help me with this.

Ive been trying to do something and no success. It seems like the stream is not well formed and I receive an error in adobe reader that says the file is corrupted.

 Here is my code:

1    string formFile = this.Server.MapPath(@"\library\doctemp\") + "cmoinmail.pdf";
2    PdfReader reader = new PdfReader(formFile);
3    MemoryStream ms = new MemoryStream();
4    PdfStamper stamper = new PdfStamper(reader, fs);
5    AcroFields fields = stamper.AcroFields;
6                            
7                            
8    fields.SetField("subtotal", this.Order.SubTotal.ToString());
9    fields.SetField("discount", this.Order.Discount.ToString());
10  fields.SetField("tax", this.Order.Tax.ToString());
11  fields.SetField("shipping", this.Order.Shipping.ToString());
12  fields.SetField("total", this.Order.Total.ToString());
13   
14  stamper.Writer.CloseStream = false;
15                           
16  stamper.FormFlattening = true;
17  stamper.Close(); 
18   
19  MailAddress maFrom = new MailAddress("some@domain.com")
20  MailAddress maTo = new MailAddress(another@domain.com);
21  MailMessage email = new MailMessage(maFrom, maTo);
22  email.Subject = "Your new order at EvanTell";
23  Attachment attch = new Attachment(ms, new System.Net.Mime.ContentType("application/pdf"));
24  email.Attachments.Add(attch);
25   
26  SmtpClient mailSender = new SmtpClient("server");
27  mailSender.Send(email);

Hi!

I was struggling with this exact problem, and ultimately I found a solution. The position of the memory stream needs to be reset before the attachment is made, so you need to insert 

ms.Position = 0

(sorry, don't know the C# equivalent... Probably ms.position(0) or something) between lines 22 and 23 in your source code, and possibly flush the stream.

Hope this helps! 

Thanks for your reply

This is a great solution

Hi there,

does anyone no the equalivent of writer.CloseStream  for the pdfwriter in vb.net?
