在asp.net中48小时后到期确认电子邮件

我向email用户发送确认,当他们点击它时,他们的帐户将变为活动状态.我唯一想要的是48小时后链接到期,用户可以再次注册username.有谁能够帮我？这是我的电子邮件代码:

   Session["UserName"] = TextBox_email.Text;

   MailMessage msg = new MailMessage();
   StringBuilder bodyMsg = new StringBuilder();

   MembershipUser user = Membership.CreateUser(TextBox_email.Text, TextBox_Pass.Text, TextBox_email.Text);

   Roles.AddUserToRole(TextBox_email.Text, "Author");
   user.IsApproved = false;
   Membership.UpdateUser(user);

 //  StringBuilder bodyMsg = new StringBuilder();

   Guid userID = (Guid)user.ProviderUserKey;


   msg.Subject = "Submission Confirmation";
   bodyMsg.Append("<html><head><img src=" + "http://waag.ir/images/header.jpg" + ">" + "<title>CONFIRMATION EMAIL:</title></head><body>");
   bodyMsg.Append("<br/>");
   string link = string.Format("http://www.waag.ir/Activate.aspx?userID={0}", userID.ToString());
   bodyMsg.Append("Dear " + RadioButtonList_Prefix.SelectedItem.Text + " " + name.Text + " " + middle.Text + " " + lastname.Text + ":<br> Thank you for registering with Avestia Publishing manuscript submission system. To confirm and complete your registration, please follow the link below:</br>" + link + "</br>This link is active for 48 hours. If the link is not visited within this time frame, your registration will be discarded and you will need to register again.</br></br></br>Best regards,</br>Avestia Publishing</br>http://avestia.com");

   msg.BodyEncoding = System.Text.Encoding.GetEncoding("utf-8");
   msg.Priority = MailPriority.High;

   msg.Body = bodyMsg.ToString();
   msg.IsBodyHtml = true;
   msg.BodyEncoding = System.Text.Encoding.GetEncoding("utf-8");
   msg.Priority = MailPriority.High;

   //  msg.ReplyTo = new MailAddress(TextBox2.Text);
   msg.From = new MailAddress("goldenstudio@goldenstudio.ir");
   msg.To.Add(new MailAddress(TextBox_email.Text));
   SmtpClient mailsender = new SmtpClient();

   mailsender.Host = "SmtpClient.goldenstudio.ir";

   mailsender.Port = 587;
   mailsender.EnableSsl = true;
   mailsender.Credentials = new System.Net.NetworkCredential("goldenstudio@goldenstudio.ir", "classaspnet");

   SmtpClient smtp = new SmtpClient();
   //Literal1.Text = "<script>alert(' ')</script>";
   smtp.Send(msg);

在Users表中添加一个列(我假设您有一个)ConfirmationDueDate,并将其设置为从用户单击OK创建帐户开始的48小时.当用户单击该链接时,如果当前时间超过该ConfirmationDueDate值,请将其带回帐户创建页面.
