        FilePath = Server.MapPath("");                                             //映射路径，不使用固定编码路径
        Attachment MyAttchment = new Attachment(FilePath + "\\MailSendTest.txt");  //附件对象
       
        MailMessage WantSendMail=new MailMessage();                                //邮件对象
        WantSendMail.From = new MailAddress("[email protected]");
        WantSendMail.To.Add("[email protected]");
        WantSendMail.Subject = "标题";
        WantSendMail.Body = "主体";

        SendClient.Send(WantSendMail);
