namespace Rebildpark.Controllers
{
    public class ContactController : Umbraco.Web.Mvc.SurfaceController
    {
        [HttpPost]
        public ActionResult SendMail(Contact form)
        {
            string retValue = "Der opstod en fejl, prøv igen senere eller kontakt via email istedet.";
            if (!ModelState.IsValid)
            {
                return Content(retValue);
            }

            if (ModelState.IsValid)
            {
                //Update your SMTP server credentials
                using (var client = new SmtpClient
                {
                    Host = "smtp.gmail.com",
                    Port = 587,
                    EnableSsl = true,
                    Credentials = new NetworkCredential("HIDDEN","HIDDEN"),
                    DeliveryMethod = SmtpDeliveryMethod.Network
                })
                {
                    var mail = new MailMessage();
                    mail.To.Add("HIDDEN"); // Update your email address
                    mail.From = new MailAddress(form.Email, form.Name);
                    mail.Subject = String.Format("Rebil Park Kontakt Formel fra - {0}", form.Name);
                    mail.Body = form.Message;
                    mail.IsBodyHtml = false;
                    try
                    {
                        client.Send(mail);
                        retValue = "Din besked er blevet sendt, du vil få svar hurtigst muligt";
                    }
                    catch (Exception e)
                    {

                        throw e;
                    }
                }
            }
            return Content(retValue);
