背景：現在幾乎每個企業都要用到郵箱，而在大客戶量情況下，為我們的不同等級的客戶送上節日關懷，以及把我們的喜訊、新品通知到他們是我們急需解決的問題。效果如圖

思路：

1、靜態化網頁模版，首先考慮需要發送什么，把需要的東西做成小而精美的html靜態化頁面以待發送時候用到；

2、關于發送問題，點擊“發送郵件”彈出群發郵件的框，填寫主題、html的服務器所在地址、收件人（多個）；

3、群發的實現。

代碼C#：

/// <summary>/// 發送失敗的郵箱地址搜集參數/// </summary>PRivate string errorMail;

群發郵件點擊事件

protected void BtnSendMail_Click(object sender, EventArgs e) { if (string.IsNullOrEmpty(txTopic.Value)) { MessageShow("郵件主題必填"); return; } if (string.IsNullOrEmpty(txUrl.Value)) { MessageShow("URL內容必填"); return; } if (string.IsNullOrEmpty(txTo.Value)) { MessageShow("收件人必填"); return; } string email = ConfigurationManager.AppSettings["ManagerSendMailUserName"].ToString(); //登錄用戶郵箱 string emailpwd = ConfigurationManager.AppSettings["ManagerSendMailUserPwd"].ToString(); //登錄用戶郵箱密碼 string s = GetHtmlCode(txUrl.Value, "gb2312"); bool restr = Sendmail(email, txTo.Value, txTopic.Value, true, s, "smtp.exmail.QQ.com", email, emailpwd); if (restr) { ClientScr

/// <summary> /// 發送郵件 /// </summary> /// <param name="from">發送人郵件地址</param> /// <param name="to">接收人郵件地址</param> /// <param name="subject">郵件主題</param> /// <param name="isBodyHtml">是否是Html</param> /// <param name="body">郵件體</param> /// <param name="smtpHost">SMTP服務器地址,例如:smtp.163.com</param> /// <param name="userName">用戶名</param> /// <param name="passWord">密碼</param> /// <returns>是否成功</returns> public bool Sendmail(string from, string to, string subject, bool isBodyHtml, string body, string smtpHost, string userName, string password) { bool isSuccess = true; string[] ts = null; if (!string.IsNullOrEmpty(to)) { if (to.Contains(";")) ts = to.Split(';'); else ts = new string[] { to }; foreach (string t in ts) { if (!string.IsNullOrEmpty(t)) { MailMessage mm = new MailMessage(); mm.From = new MailAddress(from); mm.To.Add(new MailAddress(t)); mm.Subject = subject; mm.IsBodyHtml = isBodyHtml; mm.Body = body; SmtpClient sc = new SmtpClient(); sc.Host = smtpHost; sc.Port = 25; sc.EnableSsl = false; sc.Credentials = new NetworkCredential(userName, password); sc.UseDefaultCredentials = true; sc.Credentials = new System.Net.NetworkCredential(userName, password); sc.DeliveryMethod = SmtpDeliveryMethod.Network; try { sc.Send(mm); } catch (Exception x) { errorMail += t + ";"; isSuccess = false; continue; } } } } return isSuccess; }

/// <summary> /// 獲取指定路徑下的模板的HTML源代碼 /// </summary> /// <param name="TemplatePath">模板的路徑</param> /// <param name="EncodingType">網頁類型（有些是UTF8，有些是GB2312）</param> /// <returns>源代碼</returns> private string GetHtmlCode(string TemplatePath, string EncodingType) { try { if (TemplatePath != string.Empty) { string ForesideUriPath = string.Empty; if (!TemplatePath.ToLower().StartsWith("http://")) ForesideUriPath = HttpContext.Current.Server.MapPath("~/") + TemplatePath; else ForesideUriPath = TemplatePath; WebClient webClient = new WebClient(); //設置網絡憑證為系統憑證 webClient.Credentials = CredentialCache.DefaultCredentials; //獲取指定URI的網頁的源代碼 byte[] byteDataBuffer = webClient.DownloadData(ForesideUriPath); string htmlCode = ""; if (EncodingType == "UTF8") { htmlCode = Encoding.UTF8.GetString(byteDataBuffer); } else { htmlCode = Encoding.GetEncoding(EncodingType).GetString(byteDataBuffer); } htmlCode = Regex.Replace(htmlCode, @"<!DOCTYPE/s*HTML/s*PUBLIC[^>]+>", "", RegexOptions.Singleline); htmlCode = Regex.Replace(htmlCode, @"/s+", " ", RegexOptions.Singleline); return htmlCode; } else { return ""; } } catch (Exception ee) { throw (ee); } }

總結：這個功能還是非常有用的，大家可以擴展，定時發送什么，實現各種爛漫的功能。最后說一聲，祝大家羊年大吉，心想事成！
