ASP.NET MVC Action的参数名与参数类型不一致，取不到Request数据

问题代码：

    　　 [AcceptVerbs(HttpVerbs.Post)]
        public ActionResult Manager(PocRequest model)//需要把model 换成PocRequest(大小写无所谓)
        {

            if (ModelState.IsValid)
            {
                db.Update(pocRequest);
                db.SaveChanges();

return RedirectToAction("Index", "AgilePoint/TaskPage");
            }
            return View(new PocRequestFormViewModel(pocRequest));
        }
