.net中 发送邮件内容嵌入图片的具体实例

System.Net.Mail.MailMessage mailMessage = new System.Net.Mail.MailMessage();
mailMessage.From=”发送者邮箱”;
mailMessage.To.Add(“收件人邮件列表”);
mailMessage.CC.Add(“抄送人邮件列表”);
mailMessage.Subject = subject;
AlternateView htmlBody = AlternateView.CreateAlternateViewFromString(content,null,”text/html”);
LinkedResource lrImage = new LinkedResource(“a.jpg-600″,”image/gif”);
lrImage.ContentId = “Email001”;
htmlBody.LinkedResources.Add(lrImage);
mailMessage.AlternateViews.Add(htmlBody);
SmtpClient.Send(mailMessage);

SmtpClient smtp = new SmtpClient();
smtp.DeliveryMethod = SmtpDeliveryMethod.Network;
smtp.Host = “smtp.163.com”;
smtp.Credentials = new NetworkCredential(“renzhijie1111”, “**”);

MailMessage mm = new MailMessage();
mm.From = new MailAddress(“[email protected]”, “无敌任志杰测试”);
mm.To.Add(“[email protected]”);

mm.Subject = “发送带图片邮件”;

string plainTextBody = “如果你邮件客户端不支持HTML格式，或者你切换到“普通文本”视图，将看到此内容”;
mm来源gaodaimacom搞#代%码网.AlternateViews.Add(AlternateView.CreateAlternateViewFromString(plainTextBody, null, “text/plain”));

////HTML格式邮件的内容
string htmlBodyContent = “如果你的看到这个， 说明你是在以 HTML 格式查看邮件

“;
htmlBodyContent += ” “;   //注意此处嵌入的图片资源
AlternateView htmlBody = AlternateView.CreateAlternateViewFromString(htmlBodyContent, null, “text/html”);

LinkedResource lrImage = new LinkedResource(@”d:\1.jpg-600″, “image/gif”);
lrImage.ContentId = “weblogo”; //此处的ContentId 对应 htmlBodyContent 内容中的 cid: ，如果设置不正确，请不会显示图片
htmlBody.LinkedResources.Add(lrImage);

mm.AlternateViews.Add(htmlBody);

////要求回执的标志
mm.Headers.Add(“Disposition-Notification-To”, “[email protected]”);

////自定义邮件头
mm.Headers.Add(“X-Website”, “https://www.gaodaima.com/”);

////针对 LOTUS DOMINO SERVER，插入回执头
mm.Headers.Add(“ReturnReceipt”, “1”);

mm.Priority = MailPriority.Normal; //优先级
mm.ReplyTo = new MailAddress(“[email protected]”, “我自己”);

////如果发送失败，SMTP 服务器将发送 失败邮件告诉我
mm.DeliveryNotificationOptions = DeliveryNotificationOptions.OnFailure;

////异步发送完成时的处理事件
smtp.SendCompleted += new SendCompletedEventHandler(smtp_SendCompleted);

////开始异步发送

smtp.SendAsync(mm, null);
