i'm new in asp MVC so I will try to make a login form with ajax so i write jsonresult to check the username and password in the controller and i call it in ajax but it's not working and i don't know why so that's my controller code

 public ActionResult login()
    {
        return View();
    }


    [HttpPost]

    public JsonResult ValidateUser(string username,string password)
    {
        using(var contxt=new EnglisCenterEntities())
        {
            var data = from a in contxt.Employee
                       where a.Username == username && a.Passwords == password
                       select a;
            if(data.Count()>0)
            {
                return Json(new { Success = true }, JsonRequestBehavior.AllowGet);
            }
            else
            {
                return Json(new { Success = false }, JsonRequestBehavior.AllowGet);
            }
        }
    }

    There is no need of JSON.stringify, modify your ajax call data as shown :-

    $.ajax({
              url: "/Account/ValidateUser",
              type: "Post",
              data: data,
              dataType: "json",
              .....
    });
