1、发送邮件类，百度一大堆，这里用的也是直接百度拿过来的

public static bool get_send_email(email email, string Title, string Body) {
　　MailMessage mailMsg = new MailMessage();
　　mailMsg.From = new MailAddress(email.sendmail, email.sendname);
　　mailMsg.To.Add(new MailAddress(email.acceptmail));
　　mailMsg.Subject = Title;
　　mailMsg.Body = Body;
　　SmtpClient client = new SmtpClient();
　　client.Host = "smtp.qq.com";
　　client.Port = 587;
　　client.EnableSsl = true;
　　client.Credentials = new NetworkCredential(email.sendmail, email.token);
try {
　　client.Send(mailMsg);
}
catch ( SmtpException ex ) {
return false;
}
return true;
}

添加引用web/h_r.sys引用service/h_r.base、service/data/h_r.efdata、common/h_r.common

不存在分层，只看做是一个demo即可。
