微软的发送邮件的简单实现

在配置文件的configuration节点下加入如下配置

<system.net>
    <mailSettings>
      <smtp deliveryMethod="Network" from="dongchao5525@126.com"  >
        <network host="smtp.126.com" userName="dongchao5525" password="XXXXXX"/>
      </smtp>
    </mailSettings>
  </system.net>

之后在C#代码中

using (MailMessage mmConfig = new MailMessage())
            {
                mmConfig.To.Add("dongchao5525@163.com");
                mmConfig.Subject = "123";
                mmConfig.Body = "te";
                using (SmtpClient mailClient = new SmtpClient())
                {
                    mailClient.Send(mmConfig);
                }
            }
