Two Emails on one button click with two different mesages

You will have to generalize the function and call twice as I did below

    protected void btnSendEmail_Click(object sender, EventArgs e)
    {
        string subject = "Email testing";
        string body = "User Name Is:" + TxtName.Text + "<br>" + "Email Id Is: " + Txtemail.Text + "<br>" + "Message Is:" + TxtMessage.Text;
        string to = "webquestionss@gmail.com" + "," + Txtemail.Text;
        SendEmail(to, subject, body);

        //Thank you email
        to = Txtemail.Text;
        subject = "Thank you";
        body = "Thank you";
        SendEmail(to, subject, body);
    }
    private void SendEmail(string to, string subject, string body)
    {
        MailMessage mail = new MailMessage();
        mail.From = new MailAddress("webquestionss@gmail.com");
        foreach (string email in to.Split(','))
        {
            mail.To.Add(email);
        }
        mail.Subject = subject;
        mail.Body = body;
        mail.IsBodyHtml = true;
        SmtpClient smtp = new SmtpClient();
        smtp.Host = "smtp.gmail.com";
        smtp.Credentials = new System.Net.NetworkCredential("webquestionss@gmail.com@gmail.com", "password");
        smtp.EnableSsl = true;
        smtp.Send(mail);
    }
