    //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 += "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);

    try
    {
        //here on button click what will done 
        SendMail();
        DisplayMessage.Text = "Your Comments after sending the mail";
        DisplayMessage.Visible = true;
        YourSubject.Text = "";
        YourEmail.Text = "";
        YourName.Text = "";
        Comments.Text = "";
    }
    catch (Exception) { }
}

The above code has the validation checks also.

Good Morning Muhammad Kashif Saeed
Thank you for your excellent post. I had a small problem the first time I tried it, then I reversed the settings as follows
 
smtp.Send(toAddress, fromAddress, subject, body);
 
and it worked for me.
 
Regards
