这篇文章主要介绍了.net中 发送邮件内容嵌入图片的具体实例,需要的朋友可以参考下
例程一
邮件内容调用图片格式为：<img src="cid:Email001">
发送邮件的服务端代码为：
SmtpClient 发送邮件的对象 //代码省略
代码如下:
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","image/gif");
lrImage.ContentId = "Email001";
htmlBody.LinkedResources.Add(lrImage);
mailMessage.AlternateViews.Add(htmlBody);
SmtpClient.Send(mailMessage);
例程二
代码如下:
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("renzhijie1111@163.com", "无敌任志杰测试");
mm.To.Add("renzhijie1990@vip.qq.com");
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.AlternateViews.Add(AlternateView.CreateAlternateViewFromString(plainTextBody, null, "text/plain"));
////HTML格式邮件的内容
string htmlBodyContent = "如果你的看到<b>这个</b>， 说明你是在以 <span style="color:red">HTML</span> 格式查看邮件<br><br>";
htmlBodyContent += "<a href="http://www.jb51.net//%22%3EVA娱乐网</a> <img src="cid:weblogo">";//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", "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", "renzhijie1111@163.com");
////自定义邮件头
mm.Headers.Add("X-Website", "http://www.jb51.net/");
////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("renzhijie1111@163.com", "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);
