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("[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.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", "[email protected]"); ////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("[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);
