Following code was working for me
protected void SendMail()
{
// Gmail Address from where you send the mail
var fromAddress = "Gmail@gmail.com";
// any address where the email will be sending
var toAddress = YourEmail.Text.ToString();
//Password of your gmail address
const string fromPassword = "Password";
// Passing the values and make a email formate to display
string subject = YourSubject.Text.ToString();
string body = "From: " + YourName.Text + "\n";
body += "Email: " + YourEmail.Text + "\n";
body += "Subject: " + YourSubject.Text + "\n";
body += "Question: \n" + Comments.Text + "\n";
// smtp settings
var smtp = new System.Net.Mail.SmtpClient();
{
smtp.Host = "smtp.gmail.com";
smtp.Port = 587;
smtp.EnableSsl = true;
smtp.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network;
smtp.Credentials = new NetworkCredential(fromAddress, fromPassword);
smtp.Timeout = 20000;
}
// Passing values to smtp object
smtp.Send(fromAddress, toAddress, subject, body);
}
