Your mvc controller should look like this :
public class GoogleFormController : Controller
{
[HttpPost]
public ActionResult SendConfirmationEmail(FormData formData)
{
// Send email. See http://aboutcode.net/postal/
// I'm assuming you're returning json.
return Json(formData);
}
public class FormData
{
public string fieldOne { get; set; }
public string fieldTwo { get; set; }
}
}
