实现过程

控制器代码

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;namespace MvcApplication1.Controllers
{public class HomeController : Controller{//// GET: /Home/public ActionResult Index(string name){if (name==null){ViewBag.list = BLL.PlayerManager.Show();return View();}else{ViewBag.list = BLL.PlayerManager.Find(name);return View();}}public ActionResult Delect(int id) {BLL.PlayerManager.Delect(id);return RedirectToAction("Index");}public ActionResult Deile(int id){var model=  DAL.PlayerServices.FindModel(id);ViewBag.goodname = model.goodname;ViewBag.price = model.price;ViewBag.launchtime = model.launchtime;ViewBag.description = model.description;return View();}}
}

DAL

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using MvcApplication1.Models;
namespace MvcApplication1.DAL
{public class PlayerServices{public static List<good> Show() {ProductDBEntities db = new ProductDBEntities();return db.goods.ToList();}public static List<good> Find(string name){ProductDBEntities db = new ProductDBEntities();return db.goods.Where(x => x.goodname.Contains(name)).ToList();}public static good FindModel(int id){ProductDBEntities db = new ProductDBEntities();return db.goods.SingleOrDefault(x => x.goodid == id);}public static bool Delect(int id){ProductDBEntities db = new ProductDBEntities();db.Entry(FindModel(id)).State = System.Data.EntityState.Deleted;return db.SaveChanges() > 0;}}
}

BLL

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using MvcApplication1.Models;
namespace MvcApplication1.BLL
{public class PlayerManager{public static List<good> Show(){return DAL.PlayerServices.Show();}public static List<good> Find(string name){return DAL.PlayerServices.Find(name);}public static bool Delect(int id){return DAL.PlayerServices.Delect(id);}}
}

Index

@{Layout = null;
}<!DOCTYPE html><html>
<head><meta name="viewport" content="width=device-width" /><title>Index</title>
</head>
<body><div><form  action="/Home/Index"><label>关键词</label><input type="text" name="name"/><input type="submit"  value="查询"></form><table border="1"><tr><th>商品名称</th><th>价格</th><th>上架时间</th><th>操作</th></tr>@foreach (var item in @ViewBag.list as List<MvcApplication1.Models.good>){<tr><td>@item.goodname</td><td>@item.price</td><td>@item.launchtime.ToString("yyyy年MM月dd日")</td><td>@Html.ActionLink("删除", "Delect", new { id = @item.goodid }, new { onclick="return confirm('确定删除吗？')"})@Html.ActionLink("详情", "Deile", new { id = @item.goodid })</td></tr>}</table></div>
</body>
</html>

Deile

@{Layout = null;
}<!DOCTYPE html><html>
<head><meta name="viewport" content="width=device-width" /><title>Deile</title>
