        }

        public ActionResult ContentResult()

        {

            return Content("Hi, 我是ContentResult结果");

        }

        public ActionResult EmptyResult()

        {

            //空结果当然是空白了!

            //至于你信不信, 我反正信了

            return new EmptyResult();

        }

        public ActionResult FileResult()

        {

            var imgPath = Server.MapPath("~/demo.jpg");

            return File(imgPath, "application/x-jpg", "demo.jpg");

        }

        public ActionResult HttpNotFoundResult()

        {

            return HttpNotFound("Page Not Found");

        }

        public ActionResult HttpUnauthorizedResult()

        {

            //未验证时,跳转到Logon

            return new HttpUnauthorizedResult();

        }

        public ActionResult JavaScriptResult()

        {

            string js = "alert(\"Hi, I'm JavaScript.\");";

            return JavaScript(js);

        }

        public ActionResult JsonResult()

        {

            var jsonObj = new

            {

                Id = 1,

                Name = "小铭",

                Sex = "男",

                Like = "足球"

            };

            return Json(jsonObj, JsonRequestBehavior.AllowGet);

        }

        public ActionResult RedirectResult()

        {

            return Redirect("~/demo.jpg");

        }

        public ActionResult RedirectToRouteResult()

        {

            return RedirectToRoute(new {

                controller = "Hello", action = ""

            });

        }

        public ActionResult ViewResult()

        {

            return View();

        }

        public ActionResult PartialViewResult()

        {

            return PartialView();

        }

        //禁止直接访问的ChildAction

        [ChildActionOnly]

        public ActionResult ChildAction()

        {

            return PartialView();

        }

        //正确使用ChildAction

        public ActionResult UsingChildAction()

        {

            return View();

        }

    }
