Question

I am trying to get an uploaded file to be sent as an attachment in my ashx file. Here is the code I am using:

HttpPostedFile fileupload = context.Request.Files[0];

//filename w/o the path
string file = Path.GetFileName(fileupload.FileName);

MailMessage message = new MailMessage();

//*****useless stuff********
message.To.Add("[e-mail]");
message.Subject = "test";
message.From = new MailAddress("[e-mail]");
message.IsBodyHtml = true;
message.Body = "testing";
 //*****useless stuff********

//Fault line
message.Attachments.Add(new Attachment(file, MediaTypeNames.Application.Octet))

//Send mail 
SmtpClient smtp = new System.Net.Mail.SmtpClient("xxxx", 25);
smtp.UseDefaultCredentials = false;
smtp.Credentials = new NetworkCredential("xxx", "xxxx");
smtp.Send(message);

I am able to send the email without the attachment.
Do I need to save the file first and then add to attachment?

Answer 1

FileName is the name of the file on the client, not on the server. You will need to use SaveAs or the InputStream to get any content into the attachment.

Here is a link to the MSDN documentation.
