Question

i am trying to avoid the wait time, taken by sending an email
before exiting page.

the page/application is doing a sequence of actions before exiting as follows :

1. database interaction
2. Send Email (updates a manager about that transaction)
3. Exit page / application .

code behind function :

    ExecEntryOnTbl(SQL);// <-- update / insert to database 
    sendMailNote(action);// <-- send mail with notification of update 

    exitTC(action, custid);<-- exit page.

    done via javascript :
    window.location.href = "someOtherPage.aspx"
    from code behind via 
    RegisterClientScriptBlock(...)

i would like to solve the issue :

how can i avoid waiting for the sendMailNote() to complete
before following exitTC() could be executed. is that possible ?

• update email class/method

  public static class mail
  {
      public static string aReciver, bSubject, cBody;
      public static void sendMailNoteExc()
      {
  
          string SmtpServer = "smtp.gmail.com";
          int port = 111;
          string sender = "[e-mail]";
          string ReCiver = aReciver;
          string Subject = bSubject;
          string Body = cBody;
          string account = "[e-mail]";
          string Pass = "a123456";
          Send(SmtpServer, port, account, Pass, sender, ReCiver, Subject, Body);
  
      }
      public static void Send(string smtpServer,int Port,string Account, string PassWord, string From, string To, string Subject, string Body)
      {
  
          MailMessage mail = new MailMessage();
          SmtpClient SmtpServer = new SmtpClient(smtpServer);
  
          mail.From = new MailAddress(From);
          mail.To.Add(To);
          mail.Subject = Subject;
          mail.Body = Body;
  
  
          SmtpServer.Port = Port;
          SmtpServer.Credentials = new System.Net.NetworkCredential(Account, PassWord);
          SmtpServer.EnableSsl = true;
  
          SmtpServer.Send(mail);
  
  
      }
  }

As long as you are using C# 4.0 you can take advantage of Task Parallel Library and run sendMailNote(action) in the background thread like this:

Task.Factory.StartNew(() => sendMailNote(action));

Just make sure you add a code to handle any exceptions occured during sending an email. However the better solution would be to remove this logic from the user interface code altogether and execute it in a background task like windows service or cloud worker role.
