/// <summary>
 /// 发送邮件
 /// </summary>
 /// <param name="to">收件人（多人由;隔开）</param>
 /// <param name="title">标题</param>
 /// <param name="content">内容</param>
 /// <param name="cc">抄送</param>
 /// <returns></returns>
 public string sendEmail(string to, string title, string content, string cc = "")
 {
  try
  {
   System.Net.Mail.MailMessage myMail = new System.Net.Mail.MailMessage();
   myMail.From = new System.Net.Mail.MailAddress("xxx@qq.com","xx通知", System.Text.Encoding.UTF8); //发件人地址，发件人姓名，编码
   string[] tos = to.Split(new string[] { ";" }, StringSplitOptions.RemoveEmptyEntries);
   for (int i = 0; i < tos.Length; i++)
   {
    myMail.To.Add(new System.Net.Mail.MailAddress(tos[i]));
   }
   string[] ccs = cc.Split(new string[] { ";" }, StringSplitOptions.RemoveEmptyEntries);
   for (int i = 0; i < ccs.Length; i++)
   {
    myMail.CC.Add(new System.Net.Mail.MailAddress(ccs[i]));
   }
   myMail.Subject = title;
   myMail.SubjectEncoding = Encoding.UTF8;
   myMail.Body = content;
   myMail.BodyEncoding = Encoding.UTF8;
   myMail.IsBodyHtml = true;
   System.Net.Mail.SmtpClient smtp = new System.Net.Mail.SmtpClient();
   smtp.Host = "smtp.qq.com";   smtp.EnableSsl = true;
   smtp.UseDefaultCredentials = false;
   smtp.Credentials = new System.Net.NetworkCredential("xxx@qq.com", "password");
   smtp.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network;
   smtp.Send(myMail);
   return "";
  }
  catch (Exception ee)
