利用 GMail 傳送 EMAIL

首先要擁有一個 GMail 帳號，並了解其主機及Port 號。

我們為gMail 建立一個 Class，命名為ClassGMail:

   1: using System;

   2: using System.Text;

   3: using System.Net.Mail;

   4: using System.ComponentModel;

   5:  

   6: namespace Cht_MobileNms

   7: {

   8:     class ClassGMail

   9:     {

  10:             /* gMail的 SMTP 主機及 Port*/

  11:             private System.Net.Mail.SmtpClient MySmtp;

  12:  

  13:             private MailMessage Mail;

  14:            

  15:             public string eMailAccount { private get; set; }

  16:             public string eMailPassword { private get; set; }

  17:  

  18:             public string mListDestAddr { private get; set; }

  19:             public string mASubject { private get; set; }

  20:             public string mABody { private get; set; }

  21:  

  22:             /* BackgroundWorker */

  23:             private System.ComponentModel.BackgroundWorker bwSendMail;

  24:

  31:             public ClassGMail(string Account, string Password)

  32:             {

  34:                 MySmtp = new System.Net.Mail.SmtpClient("smtp.gmail.com", 587);

  35:  

  36:                 /*設定你的帳號密碼*/

  37:                 eMailAccount = Account;

  39:  

  40:                 /*Gmial 的 smtp 使用 SSL*/

  41:                 MySmtp.Credentials = new System.Net.NetworkCredential(eMailAccount, eMailPassword);

  42:                 MySmtp.EnableSsl = true;

  43:  

  44:                 /* 背景執行物建初始化 */

建構一個GMail實體:

   1: /// <summary>

   2: /// 電子郵件

   3: /// </summary>

   4: ClassGMail infoMail = new ClassGMail("WXYZ@gmail.com", "1234567");   // 帳號及密碼作為參數

傳送eMmail:

   1: //.. 傳送 eMail 給相關人員

   2: if (MailAlarmBody.Length > 0)

   3: {

   4:     try

   5:     {

   6:         infoMail.sendMailTo(getEMailAddress(), "CHT_NMS", MailAlarmBody.ToString());

   7:     }

   8:     catch { }

   9: }

可以一次傳送給多人，可從資料庫中取得資料串接收件人。

   1: /*從 DB 取得 eMailAddress*/

   2:        private string getEMailAddress()

   3:        {

   4:            linq = new EbNoClassDataContext(cnString);

   5:  

   6:            var result = from info in linq.User

   7:                         select new

   8:                         {

   9:                             info.eMail

  10:                         };

  11:  

  12:            StringBuilder sb = new StringBuilder();

  13:            foreach (var addr in result)

  14:            {

  15:                sb.Append(addr.eMail.ToString() + ';');

  16:            }

  17:  

  18:            return (sb.ToString());

  19:        }
