C#发邮件内嵌图片例子一

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

</pre><pre name="code" class="csharp">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);
