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: 25: 26: /// <summary>
27: /// 建構式 1
28: /// </summary>
29: /// <param name="eMailAccount"></param>
30: /// <param name="Password"></param>
31: public ClassGMail(string Account, string Password)
32: {33: /*建立 SmtpClient 物件 並設定 Gmail的smtp主機及Port */
34: MySmtp = new System.Net.Mail.SmtpClient("smtp.gmail.com", 587);
35: 36: /*設定你的帳號密碼*/
37: eMailAccount = Account; 38: eMailPassword = Password; 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 */
45: this.bwSendMail = new System.ComponentModel.BackgroundWorker();
46: this.bwSendMail.DoWork += new System.ComponentModel.DoWorkEventHandler(this.bwSendMail_DoWork);
47: } 48: 49: /// <summary>
50: /// 傳送 EMAIL
51: /// </summary>
52: /// <param name="ListDestAddr"></param>
53: /// <param name="ASubject"></param>

55: /// <returns></returns>
56: public void sendMailTo(String ListDestAddr, String ASubject, String ABody)
57: { 58: mListDestAddr=ListDestAddr; 59: mASubject=ASubject; 60: mABody = ABody; 61: 62: /* 背景執行 eMail 傳送 */
63: try
64: { 65: bwSendMail.RunWorkerAsync(); 66: }67: catch
68: { 69: } 70: } 71: 72: private void bwSendMail_DoWork(object sender, DoWorkEventArgs e)
73: { 74: PrivateSendMailTo(mListDestAddr, mASubject, mABody); 75: } 76: 77: 78: /// <summary>

84: /// <returns></returns>
85: private void PrivateSendMailTo(String ListDestAddr, String ASubject, String ABody)
86: {87: try
88: {89: //============================================================
90: Mail = new MailMessage();
91: Mail.From = new MailAddress(eMailAccount);
92: Mail.Subject = ASubject.Trim().ToString(); 93: Mail.Body = ABody.Trim().ToString(); 94: 95: /* 分解多個 目的位址 */
96: string[] AList = ListDestAddr.Split(';');
97: int Cnt = AList.GetLength(0);
98: 99: foreach (string Addr in AList)
100: {101: if (Addr != "") { Mail.To.Add(Addr.Trim().ToString()); }
102: }103: //============================================================
104: 105: /*發送Email*/
106: MySmtp.Send(Mail); 107: }108: catch (Exception err)
109: { 110: // MessageBox.Show(err.Message);
111: // throw (err);
112: } 113: } 114: 115: 116: } 117: 118: 119: }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: }
