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);
