怎么做邀请好友的功能

Question

要在回会员中心做一个邀请好友，可以通过发送到邮箱，可以是发链接。发邮件的时候，发送不报错，也没有发送成功！ MailSender ms = new MailSender(); ms.From = "[e-mail]"; ms.To = "[e-mail]"; ms.Subject = "Subject"; ms.Body = "body text"; ms.UserName = "******@163.com"; // 怎么能告诉你呢 ms.Password = "******"; // 怎么能告诉你呢 ms.Server = "smtp.163.com"; ms.Attachments.Add(new MailSender.AttachmentInfo(@"D:\test.txt")); Console.WriteLine("mail sending..."); try { ms.SendMail(); Console.WriteLine("<script>alert('mail sended');</script>"); } catch (Exception ex) { Console.WriteLine(ex); } 请问是不是要设置什么？系统是windows2003
