I am getting the following error when I try to send an email in my C# program. I am using Visual Studio 2008 on windows 7. I would paste my code first and then the error:

using System;

using System.Linq;
using System.Text;
using System.IO;
using System.Net;
using System.Net.Mail;
using System.Net.Mime;
using System.Net.Sockets;
using System.Web;

class email_log_files
    {

          private string login_username = "my_gmail_id";
          private string login_password = "my_gmail_password";

          public void send_email()
          {
              string src_address = "[email protected]";
              string dest_address = "[email protected]";


              try
              {
                  MailMessage email_msg = new MailMessage();

                  SmtpClient email_client = new SmtpClient();
                  email_msg.From = new MailAddress(src_address);
                  email_msg.Sender = new MailAddress(src_address);
                  email_msg.ReplyTo = new MailAddress(src_address);
                  email_msg.To.Add(dest_address);
                  email_msg.Subject = "Test";
                  email_msg.Body = "Body of the message";
                  NetworkCredential credentials = new NetworkCredential(login_username, login_password);


                  email_client.Credentials = credentials;
                  email_client.Host = "smtp.gmail.com";
                  email_client.Port = 465;
                  email_client.EnableSsl = true;


                  email_client.Send(email_msg);
                  Console.WriteLine("Message Sent Successfully!!");
                  Console.ReadLine();

            }

                catch (Exception ex)
               {
                   Console.WriteLine(ex.Message.ToString());
                   Console.WriteLine(ex.InnerException);
                   Console.WriteLine(ex.Source);
                   Console.WriteLine(ex.Data);
                   Console.ReadLine();
               }
        }
    }

And the error message is as follows:

The operation has timed out.

System
System.Collections.ListDictionaryInternal

Why is it always timing out? I am sure that I have the correct smtp server address and port number for gmail as I have configured my outlook with the same. Any help or ideas?
