使用C＃中的SMTP发送电子邮件 [ ^ ]

try
      {
          SmtpClient emailClient = new SmtpClient("smtp.mail.yahoo.com");
          System.Net.NetworkCredential SMTPUserInfo = new System.Net.NetworkCredential("[e-mail]","myyahoopassword");
          emailClient.EnableSsl = true;
          emailClient.Credentials = SMTPUserInfo;
          emailClient.Port = 995;


          System.Net.Mail.MailMessage message = new System.Net.Mail.MailMessage("[e-mail]", "[e-mail]", "fire!!", "Call up 911 and inform my house is on fire and my phone too");
          message.Priority = System.Net.Mail.MailPriority.High;
          emailClient.Send(message);
      }
      catch (Exception ee)
      {
          lblerror.Text = ee.ToString();


      }
