控制器代码

using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using MvcApplication1.Models;
namespace MvcApplication1.Controllers
{
    public class HomeController : Controller
    {
        //
        // GET: /Home/
        public ActionResult Index(bool PriceOrderDese=false)
        {
        ViewData["goods"] = BLL.GoodsManger.Show();
       ViewData["sum"] = BLL.GoodsManger.Sun();
       ViewData["goods"] = BLL.GoodsManger.getGoodlist(PriceOrderDese);
       ViewBag.PriceOrderDese = !PriceOrderDese;
       return View();
        }
        public ActionResult DeleteGood(string goodId) {
            BLL.GoodsManger.Delect(goodId);
            return RedirectToAction("Index");
        }
        public ActionResult AddGood()
        {
            return View();
        }
        [HttpPost]
        public ActionResult AddGood(Goods good)
        {
            //获取表单验证状态
            if (ModelState.IsValid)
            {
                if (BLL.GoodsManger.AddGood(good))
                {
                    return RedirectToAction("Index");
                }
                else
