C# Attaching System.Drawing.Image to Email

Question

Is there any way to attach System.Drawing.Image to email with out saving it, then grabbing it from the saved path.

Right now I'm creating the image and saving it. I then send email with:

MailMessage mail = new MailMessage();
                string _body = "body"

                mail.Body = _body;
                string _attacmentPath;
                if (iP.Contains(":"))
                    _attacmentPath = (@"path1");//, System.Net.Mime.MediaTypeNames.Application.Octet));
                else
                    _attacmentPath = @"path2");
                mail.Attachments.Add(new Attachment(_attacmentPath, System.Net.Mime.MediaTypeNames.Application.Octet));
                mail.To.Add(_imageInfo.VendorEmail);
                mail.Subject = "Rouses' PO # " + _imageInfo.PONumber.Trim();
                mail.From = _imageInfo.VendorNum == 691 ? new MailAddress("email", "") : new MailAddress("email", "");
                SmtpClient server = null;
                mail.IsBodyHtml = true;
                mail.Priority = MailPriority.Normal; 
                server = new SmtpClient("server");
                try
                {

                    server.Send(mail);
                }
                catch
                {

                }

Is there anyway to directly pass the System.Drawing.Image to mail.Attachments.Add()?

Answer 1

You can't pass an Image directly to an attachment, but you can skip the file system by just saving the image to a MemoryStream, and then providing that MemoryStream to the attachment constructor:

var stream = new MemoryStream();
image.Save(stream, ImageFormat.Jpeg);
stream.Position = 0;

mail.Attachments.Add(new Attachment(stream, "image/jpg"));
