System.Net.Mail.MailMessage mailMessage = new System.Net.Mail.MailMessage();
mailMessage.From="     ";
mailMessage.To.Add("       ");
mailMessage.CC.Add("       ");
mailMessage.Subject = subject;
AlternateView htmlBody = AlternateView.CreateAlternateViewFromString(content,null,"text/html");
LinkedResource lrImage = new LinkedResource("a.jpg","image/gif");
lrImage.ContentId = "Email001";
htmlBody.LinkedResources.Add(lrImage);
mailMessage.AlternateViews.Add(htmlBody);
SmtpClient.Send(mailMessage);
