private void SendMail()
        {
            System.Net.Mail.MailMessage mailMessage = new System.Net.Mail.MailMessage();
            //設置發件人地址
            mailMessage.From = new System.Net.Mail.MailAddress("[email protected]");
            //添加收件人地址
            mailMessage.To.Add("[email protected]");
            mailMessage.To.Add("[email protected]");
            mailMessage.To.Add("[email protected]");
            //郵件主題
            mailMessage.Subject = "郵件主題";
            //郵件正文
            mailMessage.Body = "郵件正文";
            //正文編碼方式
            mailMessage.BodyEncoding = System.Text.Encoding.UTF8;
            //郵件正文是否為Html的值
            mailMessage.IsBodyHtml = true;
            //設置郵件發送的優先級
            mailMessage.Priority = System.Net.Mail.MailPriority.Normal;
            System.Net.Mail.SmtpClIEnt mail = new System.Net.Mail.SmtpClIEnt();
