 public void sendmail(string email,string expense,string name,string remain)
        {
            if (email == string.Empty)
            { return; }
            System.Net.Mail.MailMessage msg = new System.Net.Mail.MailMessage();
            msg.To.Add(email);
            msg.From = new MailAddress("fromclient", "title", System.Text.Encoding.UTF8);
            msg.Subject = 标题;//邮件标题   
            msg.SubjectEncoding = System.Text.Encoding.UTF8;//邮件标题编码   
            msg.Body =邮件主要内容;//邮件内容   
            msg.BodyEncoding = System.Text.Encoding.UTF8;//邮件内容编码   
            msg.IsBodyHtml = false;//是否是HTML邮件   
            msg.Priority = MailPriority.Normal;//邮件优先级 
            SmtpClient client = new SmtpClient();
            client.Credentials = new System.Net.NetworkCredential(“用户名”, “密码”); 
            client.Host = "例如：mail.163.com";
            object userState = msg;
            try
            {
                client.Send(msg);
                 
            }
            catch (System.Net.Mail.SmtpException ex)
            {
                
            }
