這兩天因為要做一個可以收集用戶提交信息，然后發送郵件到指定郵箱的網頁。在 asp.net 2.0 里面發送郵件可以使用 System.Net.Mail 下面的類。http://www.systemnetmail.com/faq/2.1.aspx 這個地址有 System.Net.Mail 的作者寫的仿佛是 MSDN 類似的 Faq，看代碼的時候可以參考以下。什么都不說了，下面貼出來代碼吧，畢竟代碼是最重要的：      

 1PRotected void btnSend_Click(object sender, EventArgs e)
 2        {
 3            MailMessage mailMessage = new MailMessage();
 4            string strBody;
 5
 6            mailMessage.From = new MailAddress("365rss@Gmail.com");
 7            mailMessage.To.Add("prlibertine@gmail.com");
 8            mailMessage.Subject = "365Rss.CN ";
 9
10            strBody = "<h2>" + ddlMainTag.SelectedItem.Text + "</h2><br>";
11            strBody += "<h4>" + tbTag.Text + "</h4><br><hr><br>";
12            strBody += "·" + tbAdv.Text;
13
14            sendMail(mailMessage);
15        }
16
17        //SendMail
18        private void sendMail(MailMessage mail)
19        {
20            SmtpClient smtpClient = new SmtpClient();
21            smtpClient.EnableSsl = true;
22            smtpClient.Host = "smtp.gmail.com";
23            smtpClient.Port = 465;
24            smtpClient.Credentials = new NetworkCredential("365rss@gmail.com", "pwd");
25            try
26            {
27                smtpClient.Send(mail);
28                Label1.Text = "ok";
29            }
30            catch
31            {
32                Label1.Text = "false";
33            }
34        }
