开发工具：VS2010+MSSQL2005,需要使用MVC3.0
环境配置
第一步：到官方网站下载MVC3,提供了简体中文。先安装 AspNetMVC3ToolsUpdateSetup.exe，然后安装AspNetMVC3ToolsUpdateVS11Setup.exe
http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=1491
第二步：新建数据库，创建测试表。然后往表里insert些测试数据

USE [yanComdb] GO /****** 对象: Table [dbo].[NewsEntity] 脚本日期: 03/12/2012 22:03:59 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO CREATE TABLE [dbo].[NewsEntity]( [NId] [int] IDENTITY(1,1) NOT NULL, [Title] [nvarchar](100) COLLATE Chinese_PRC_CI_AS NOT NULL, [Information] [text] COLLATE Chinese_PRC_CI_AS NULL, [Time] [datetime] NOT NULL CONSTRAINT [DF_NewsEntity_Time] DEFAULT (getdate()), CONSTRAINT [PK_NewsEntity] PRIMARY KEY CLUSTERED ( [NId] ASC )WITH (PAD_INDEX = OFF, IGNORE_DUP_KEY = OFF) ON [PRIMARY] ) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY] |
构建列表页面
第一步：打开VS,新建选择MVC3 web应用程序，输入项目名称以及目录
第二步：创建NewsEntity类，本文使用自己手写实体类(没有使用LinqtoSql,EF等orm)

[TableAttribute("NewsEntity")]//这行很重要，因为mvc框架默认去db中找类名复数的表名 public class NewsEntity { [Key]//设置主键 public int NId { get; set; } [StringLength(100)]//设置验证信息 [Required(ErrorMessage="标题不能为空")] [DisplayName("标题")] public string Title { get; set; } [Required(ErrorMessage = "正文必须填写")] [DisplayName("正文")] public string Information { get; set; } public DateTime Time { get; set; } } |
第三步：配置数据库连接字符，注意此处的name对应下一步中创建的类名。

<connectionStrings> <add name="ProjectEntity" connectionString="Data Source=ip;Initial Catalog=yanComdb;Persist Security Info=True;User ID=;Password="providerName="System.Data.SqlClient" /> </connectionStrings> |
第四步：创建ProjectEntity类，需要继承DbContext

public class ProjectEntity : DbContext { public DbSet<NewsEntity> NewsEntity { get; set; } } |
第五步：新建Controller,

ProjectEntity PE = new ProjectEntity(); public ActionResult News() { try { var list = PE.NewsEntity.ToList(); return View(list); } catch (Exception e) { throw e; } } |
第六步：在News上右键，新建视图。勾选“创建强类型视图”，选择NewsEntity,支架模块选择List
添加后，cshtml代码如下：

@model IEnumerable<TaiQiu.Models.NewsEntity> @{ ViewBag.Title = "后台新闻管理列表"; Layout = "~/Views/Shared/_MLayout.cshtml"; } <h2> 新闻列表</h2> <p> @Html.ActionLink("添加", "Create") </p> <table> <tr> <th width="50px"> ID </th> <th width="300px"> 标题 </th> <th width="150px"> 时间 </th> <th> </th> </tr> @foreach (var item in Model) { <tr> <td> @Html.DisplayFor(modelItem => item.NId) </td> <td> @Html.DisplayFor(modelItem => item.Title) </td> <td> @Html.DisplayFor(modelItem => item.Time) </td> <td> @Html.ActionLink("编辑", "EditNews", new { id = item.NId }) | @Html.ActionLink("删除", "DeleteNews", new { id=item.NId }) </td> </tr> } </table> |
运行后效果图如下：
到此，第一个列表页面就完成了(未涉及分页，后续会更新)。关于添加，修改，删除也就很容易了。

修改页面一样，Controller稍微有点修改：

删除Controller代码：

小编刚接触MVC3,本文也只是本人学习中的一点点积累，有很多不好的地方，希望大家多提意思。
