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;
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{return View();}}else{ViewBag.Good = good;return View();}}}
}

models 代码

//------------------------------------------------------------------------------
// <auto-generated>
//    此代码是根据模板生成的。
//
//    手动更改此文件可能会导致应用程序中发生异常行为。
//    如果重新生成代码，则将覆盖对此文件的手动更改。
// </auto-generated>
//------------------------------------------------------------------------------namespace MvcApplication1.Models
{using System;using System.Collections.Generic;using System.ComponentModel.DataAnnotations;public partial class Goods{public int GoodsID { get; set; }[Required(ErrorMessage = "商品名称是必填项")]//必填[StringLength(10, ErrorMessage = "长度错误")]//长度限制public string GoodsName { get; set; }[Required(ErrorMessage = "商品价格是必填项")]//必填  public decimal GoodsPrice { get; set; }[Required(ErrorMessage = "商品库存是必填项")]//必填  public int GoodsStock { get; set; }}
}

DAL

  public static bool AddGood(Goods good){GoodsDBEntities db = new GoodsDBEntities();db.Goods.Add(good);return db.SaveChanges() > 0;}

BLL

 public static bool AddGood(Goods good){return DAL.GoodsService.AddGood(good);}

Index

 @Html.ActionLink("添加", "AddGood")

ADD

@{Layout = null;
}<!DOCTYPE html><html>
<head><meta name="viewport" content="width=device-width" /><title>AddGood</title>
</head>
<body><div><form action="/Home/AddGood" method="post">商品名称<input type="text" name="GoodsName" value="@(ViewBag.Good!=null? ViewBag.Good.GoodsName:"")" />  @Html.ValidationMessage("GoodsName")<br />商品价格<input type="text" name="GoodsPrice"   />   @Html.ValidationMessage("GoodsPrice")<br />商品库存<input type="text" name="GoodsStock"   />@Html.ValidationMessage("GoodsStock")<br /><input type="submit" value="保存" />@Html.ValidationSummary()</form></div>
