Question

运行此程序时，我试图创建分页，我希望在一页中显示4种产品，但我没有发生，它会显示每个类别中的所有产品

public ActionResult Category(string name,int? page, int? catId)
        {

            //Declare List Of ProductVM
            List<ProductVM> listOfProductVM;
            //Set Page Number
            var pageNumber = page ?? 1;
            using (Db db = new Db())
            {

                //Get Category ID
                CategoryDTO categoryDTO = db.Categories.Where(x => x.Slug == name).FirstOrDefault();
                 catId = categoryDTO.Id;


                //Initialize The List
                        listOfProductVM = db.Products.ToArray()
                                         .Where(x => x.CategoryId == catId)
                                         .Select(x => new ProductVM(x))
                                         .ToList();


                //Get Category Name
                var productCat = db.Products.Where(x => x.CategoryId == catId).FirstOrDefault();
                ViewBag.CategoryName = productCat.CategoryName;


                //Populate Categories select list
                ViewBag.Categories = new SelectList(db.Categories.ToList(), "Id", "Name");
                //set selected category
                ViewBag.SelectedCat = catId.ToString();
            }

            //set pagination
            var onePageOfProducts = listOfProductVM.ToPagedList(pageNumber, 4);
            ViewBag.OnePageOfProducts = onePageOfProducts;
            //return view with list

            return View(listOfProductVM);
        }
