这两天因为要做一个可以收集用户提交信息，然后发送邮件到指定邮箱的网页。在 asp.net 2.0 里面发送邮件可以使用 System.Net.Mail 下面的类。http://www.systemnetmail.com/faq/2.1.aspx 这个地址有 System.Net.Mail 的作者写的仿佛是 MSDN 类似的 Faq，看代码的时候可以参考以下。什么都不说了，下面贴出来代码吧，毕竟代码是最重要的：      

 1PRotected void btnSend_Click(object sender, EventArgs e)
 2        {
 3            MailMessage mailMessage = new MailMessage();
 4            string strBody;
 5
 6            mailMessage.From = new MailAddress("[email protected]");
 7            mailMessage.To.Add("[email protected]");
 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("[email protected]", "pwd");
25            try
26            {
27                smtpClient.Send(mail);
28                Label1.Text = "ok";
29            }
30            catch
31            {
32                Label1.Text = "false";
33            }
34        }
