html代码

控制器

shopEntities shop = new shopEntities();  public ActionResult Index()  {   //IQueryable order = (from a in shop.tbl_order select a).OrderBy(a=>a.id).Skip(10).Take(10);   //ViewData["order"] = order;   //return View();   int pageIndex = Request["pageIndex"] == null ? 1 : int.Parse(Request["pageIndex"]);   int pageSize = Request["pageSize"] == null ? 10 : int.Parse(Request["pageSize"]);   int totalCount = 0;   //给前台传递 分页的参数数据   ViewData["pageIndex"] = pageIndex;   //ViewData["pageSize"] = pageSize;   ViewBag.pageSize = pageSize;   //总条数   totalCount = shop.tbl_order.Count();   ViewBag.totalCount = totalCount;   //把当前页面数据发送到前台。   //ViewData.Model = db.UserInfo.ToList();   //List pp = shop.tbl_order   //     .OrderBy(u => u.id)   //     .Skip((pageIndex - 1) * pageSize)   //     .Take(pageSize).ToList();   IQueryable pp = shop.tbl_order       .OrderBy(u => u.id)       .Skip((pageIndex - 1) * pageSize)       .Take(pageSize);   return View(pp);  }
