实现过程
1创建数据库
create database GoodsDB
CREATE TABLE Goods([GoodsID] [int] IDENTITY(1,1) NOT NULL,[GoodsName] [nvarchar](50) NOT NULL,[GoodsPrice] [decimal](10, 2) NOT NULL,[GoodsStock] [int] NOT NULL)INSERT Goods( [GoodsName], [GoodsPrice], [GoodsStock]) VALUES ( N'魔幻陀螺', CAST(19.00 AS Decimal(10, 2)), 20)
INSERT Goods( [GoodsName], [GoodsPrice], [GoodsStock]) VALUES ( N'开花精灵惊喜盲盒', CAST(89.00 AS Decimal(10, 2)), 10)
INSERT Goods ( [GoodsName], [GoodsPrice], [GoodsStock]) VALUES ( N'跳跃战士玩具2变形汽车', CAST(18.00 AS Decimal(10, 2)), 50)
INSERT Goods( [GoodsName], [GoodsPrice], [GoodsStock]) VALUES ( N'正版灵动奥特曼软胶囊玩具', CAST(25.00 AS Decimal(10, 2)), 20)
INSERT Goods ( [GoodsName], [GoodsPrice], [GoodsStock]) VALUES ( N'帮帮龙变形车套装', CAST(109.00 AS Decimal(10, 2)), 5)

4创建DAL
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using MvcApplication1.Models;
namespace MvcApplication1.DAL
{public class GoodsService{ //展示public static List<Goods> Show() {GoodsDBEntities db = new GoodsDBEntities();return db.Goods.ToList();}//计算小计public static string Sun() {GoodsDBEntities db = new GoodsDBEntities();return db.Goods.Sum(m => m.GoodsPrice * m.GoodsStock).ToString();}//找到需要删除的一条数据，后面被调用public static Goods GetID(string goodid) {GoodsDBEntities db = new GoodsDBEntities();int temp = Convert.ToInt32(goodid);return db.Goods.SingleOrDefault(m => m.GoodsID == temp);}//调用查找数据的方法进行删除public static bool Delect(string goodid) {Goods good= GetID(goodid);if (good==null){return false;}else{GoodsDBEntities db = new GoodsDBEntities();db.Entry(good).State = System.Data.EntityState.Deleted;db.Goods.Remove(good);return db.SaveChanges() > 0;}}//排序方法public static List<Goods> getGoodlist(bool priceOrder) {GoodsDBEntities db = new GoodsDBEntities();if (priceOrder==true){return db.Goods.OrderByDescending(m => m.GoodsPrice).ToList();}else{return db.Goods.OrderBy(m => m.GoodsPrice).ToList();}}}
}5创建BLL
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using MvcApplication1.Models;
namespace MvcApplication1.BLL
{public class GoodsManger{public static List<Goods> Show(){GoodsDBEntities db = new GoodsDBEntities();return db.Goods.ToList();}public static string Sun(){return DAL.GoodsService.Sun();}public static bool Delect(string goodid) {return DAL.GoodsService.Delect(goodid);}public static List<Goods> getGoodlist(bool priceOrder) {return DAL.GoodsService.getGoodlist(priceOrder);}}
}6创建视图，右键添加视图
7HomeController.cs代码
using System;
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");}}
}
8Index.cshtml代码
@{Layout = null;
}<!DOCTYPE html><html>
<head><meta name="viewport" content="width=device-width" /><title>Index</title>

<body><div><table border="1"><tr><th>ID</th><th>商品名</th><th>@Html.ActionLink("价格排序", "Index", new {PriceOrderDese=@ViewBag.PriceOrderDese})</th><th>库存</th><th>小计</th><th>操作</th></tr>@{foreach (var good in ViewData["goods"] as List<MvcApplication1.Models.Goods>){<tr><td>@good.GoodsID</td><td>@good.GoodsName</td><td>@good.GoodsPrice</td><td>@good.GoodsStock</td><td>@(@good.GoodsPrice*@good.GoodsStock)</td><td>@Html.ActionLink("删除","DeleteGood", new{goodId=good.GoodsID})</td></tr>}}<tr><td colspan="6">总计:@ViewData["sum"]</td></tr></table></div>
