using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Net;
using System.Net.Mail;
using System.Configuration;

public partial class _Default : System.Web.UI.Page 
{
    protected void Page_Load(object sender, EventArgs e)
    {
        
    }
    protected void bt_sendMail_Click(object sender, EventArgs e)
    {
        SendMail(tb_GmailAccount.Text, tb_GmailPassword.Text, tb_RecieverEmail.Text, tb_Subject.Text, tb_Message.Text);
       
    }
    public  void SendMail(string gMailAccount, string password, string to, string subject, string message)
    {
        try
        {
            MailMessage msg = new MailMessage();
            msg.From = new MailAddress(gMailAccount);
            msg.To.Add(new MailAddress(to));
            msg.Subject = subject;
            msg.Body = message;
            msg.IsBodyHtml = true;
            msg.Priority = MailPriority.Normal;
            var client = new SmtpClient("smtp.gmail.com", 587)
            {
                UseDefaultCredentials = false,
                Credentials = new NetworkCredential(gMailAccount, password),
                EnableSsl = true,
                DeliveryMethod = SmtpDeliveryMethod.Network
            };

            client.Send(msg);

        }
        catch (Exception ex)
        {
            string s = ex.Message; ;

            msg.From = new MailAddress(gMailAccount);
            msg.To.Add(new MailAddress(to));
            msg.Subject = subject;
            msg.Body = message;
            msg.IsBodyHtml = true;
            msg.Priority = MailPriority.Normal;
            var client = new SmtpClient("smtp.gmail.com", 587)
            {
                UseDefaultCredentials = false,
                Credentials = new NetworkCredential(gMailAccount, password),
                EnableSsl = true,
