        String[] email = new String[30];
        int flag = 0;
        public System.Net.NetworkCredential smtpcrede = new System.Net.NetworkCredential("username", "Password");


//Sending mail

 private void SendEmail(string sendTo, string sendFrom, string subject, string body)

                MailAddress from = new MailAddress(sendFrom);
                msg.IsBodyHtml = true;

                msg.Subject = subject;
                msg.Body = body;
                msg.From = from;
                string[] addrs = sendTo.Split(',');
                foreach (string addr in addrs)

                    MailAddress to = new MailAddress(addr);
                    msg.To.Add(to);

              for (int i = 0; i < email.Length; i++)
             {
                 SendEmail(email[i], "[e-mail]", txt_Subj.Text,mailmsg);

    {
        try
        {
            if (DropDownList1.SelectedValue == "gmail")
            {
                type = "smtp.gmail.com";
            }
            else
            {
                type = "smtp.live.com";

            }
            MailMessage msg = new MailMessage();
            msg.From = new MailAddress(TextBox1.Text);
            msg.To.Add(TextBox2.Text);
            msg.Subject = TextBox4.Text;
            msg.Body = TextBox3.Text;
            SmtpClient sc = new SmtpClient(type);
            sc.Port = 25;
            sc.Credentials = new NetworkCredential(TextBox1.Text, TextBox5.Text);
            sc.EnableSsl = true;
            sc.Send(msg);
            Response.Write("Mail sent");

        }
        catch (Exception e1)
        {
            Response.Write(e1.Message);
        }
    }
    protected void Button2_Click(object sender, EventArgs e)
    {

       
        TextBox1.Enabled = true;
        TextBox2.Enabled = true;
        TextBox3.Enabled = true;
        TextBox4.Enabled = true;
        TextBox5.Enabled = true;
    }
}

如果你想发送给多个人..只需在MailMessage部分添加一个循环，直到Response.Write（Mail发送）;



如果能解决问题，请接受答案

If u want to send to multiple people..just add a loop in the MailMessage section upto Response.Write("Mail sent");
