how to send a mail using c# in 2003 version

It is very easy to send mail using asp. I have a project on it and I am attaching it for you. You should have Visual Web Developer or Visual Studio 2003 or above. Notice one thing you just have to change the smtp credentials in web.config file as per your email service provider.

Thanks

using System;
using System.Collections.Generic;
using System.Text;
using System.Net;
using System.Net.Mail;

namespace consolemail
{
    class Program
    {
        static void Main(string[] args)
        {
            MailMessage message = new MailMessage();
            SmtpClient smtp = new SmtpClient();
            System.Net.NetworkCredential AuthInfo = new
            System.Net.NetworkCredential("[email protected]", "babilona");

            message.To.Add("[email protected]");

            message.Subject = "Test Mail using System.Net.Mail";
            message.From = new MailAddress("[email protected]");
            string str = "Hai to all";
            message.Body = str;
            bool isBodyHtml = true;
            message.IsBodyHtml = isBodyHtml;
            message.Attachments.Add(new Attachment("c:\\something.txt"));
            message.SubjectEncoding = System.Text.Encoding.UTF8;
            message.BodyEncoding = System.Text.Encoding.UTF8;


            message.Priority = MailPriority.High;



            smtp.Host = "smtp.gmail.com";
            smtp.UseDefaultCredentials = false;
            smtp.Credentials = AuthInfo;
            smtp.Timeout = 20000;
            smtp.Port = 587;
            // use stmp.port = 587 if 465 does not work.
            smtp.EnableSsl = true;
            smtp.DeliveryMethod = SmtpDeliveryMethod.Network;

            try
            {
                smtp.Send(message);
                Console.WriteLine("E-mail has been sent succesfully");
                Console.ReadLine();
                
            }

            catch (System.Net.Mail.SmtpException ex)
            {
                Console.WriteLine(ex.Message);
                Console.ReadLine();
            }
        }
    }
}
