這篇文章主要介紹了.net中 發送郵件內容嵌入圖片的具體實例,需要的朋友可以參考下
例程一 郵件內容調用圖片格式為：<img src="cid:Email001"> 發送郵件的服務端代碼為： SmtpClient 發送郵件的對象 //代碼省略 代碼如下: System.Net.Mail.MailMessage mailMessage = new System.Net.Mail.MailMessage(); mailMessage.From="發送者郵箱"; mailMessage.To.Add("收件人郵件列表"); mailMessage.CC.Add("抄送人郵件列表"); 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 代碼如下: 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]", "無敵任志傑測試"); mm.To.Add("[email protected]"); mm.Subject = "發送帶圖片郵件"; string plainTextBody = "如果你郵件客戶端不支持HTML格式，或者你切換到“普通文本”視圖，將看到此內容"; mm.AlternateViews.Add(AlternateView.CreateAlternateViewFromString(plainTextBody, null, "text/plain")); ////HTML格式郵件的內容 string htmlBodyContent = "如果你的看到<b>這個</b>， 說明你是在以 <span style="color:red">HTML</span> 格式查看郵件<br><br>"; htmlBodyContent += "<a href="http://www.jb51.net//%22%3EVA娛樂網</a> <img src="cid:weblogo">"; //注意此處嵌入的圖片資源 AlternateView htmlBody = AlternateView.CreateAlternateViewFromString(htmlBodyContent, null, "text/html"); LinkedResource lrImage = new LinkedResource(@"d:1.jpg", "image/gif"); lrImage.ContentId = "weblogo"; //此處的ContentId 對應 htmlBodyContent 內容中的 cid: ，如果設置不正確，請不會顯示圖片 htmlBody.LinkedResources.Add(lrImage); mm.AlternateViews.Add(htmlBody); ////要求回執的標志 mm.Headers.Add("Disposition-Notification-To", "[email protected]"); ////自定義郵件頭 mm.Headers.Add("X-Website", "http://www.jb51.net/"); ////針對 LOTUS DOMINO SERVER，插入回執頭 mm.Headers.Add("ReturnReceipt", "1"); mm.Priority = MailPriority.Normal; //優先級 mm.ReplyTo = new MailAddress("[email protected]", "我自己"); ////如果發送失敗，SMTP 服務器將發送 失敗郵件告訴我 mm.DeliveryNotificationOptions = DeliveryNotificationOptions.OnFailure; ////異步發送完成時的處理事件 smtp.SendCompleted += new SendCompletedEventHandler(smtp_SendCompleted); ////開始異步發送 smtp.SendAsync(mm, null);
