【原创】ASP.NET MVC3 从零开始一步步构建Web

微软更新速度一直都是很快,目前MVC4.0Beta已经发布了,而我还在刚刚起步MVC3.0。本文是MVC的基础,构建最简单的MVC项目。以后会陆续发布更新。

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:

View Code
@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。

添加Controller代码:

       [HttpPost]
[ValidateInput(false)]
public ActionResult Create(NewsEntity news)
{
if (ModelState.IsValid)
{
news.Time = DateTime.Now;
PE.NewsEntity.Add(news);
try
{
PE.SaveChanges();
return RedirectToAction("News");
}
catch (Exception e)
{
throw e;
}

}
return View();
}

添加页面:

View Code
@model TaiQiu.Models.NewsEntity
@{
ViewBag.Title = "添加新闻";
Layout = "~/Views/Shared/_MLayout.cshtml";
}
<h2>
添加新闻</h2>
<script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/kindeditor/kindeditor.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/kindeditor/lang/zh_CN.js")" type="text/javascript"></script>
<script type="text/javascript">
var editor;
KindEditor.ready(function (K) {
editor = K.create('textarea[name="Information"]', {
allowFileManager: true
});
});
</script>
@using (Html.BeginForm())
{
@Html.ValidationSummary(true)
<fieldset>
<legend>News</legend>
<div class="editor-label">
@Html.LabelFor(model => model.Title)
</div>
<div class="editor-field">
@Html.TextBoxFor(model => model.Title, new { style = "width:500px" })
@Html.ValidationMessageFor(model => model.Title)
</div>
<div class="editor-label">
@Html.LabelFor(model => model.Information)
</div>
<div class="editor-field">
@Html.TextAreaFor(model => model.Information, new { style="width:800px;height:400px"})
@Html.ValidationMessageFor(model => model.Information)
</div>
<p>
<input type="submit" value="Create" />
</p>
</fieldset>
}
<div>
@Html.ActionLink("返回列表", "Index")
</div>

修改页面一样,Controller稍微有点修改:

     [HttpPost]
[ValidateInput(false)]
public ActionResult EditNews(NewsEntity news)
{
if (ModelState.IsValid)
{
news.Time = DateTime.Now;
PE.Entry(news).State = EntityState.Modified;//修改
PE.SaveChanges();
return RedirectToAction("News");
}
return View(news);
}

删除Controller代码:

      public ActionResult DeleteNews(int id)
{
var model = PE.NewsEntity.Find(id);
PE.NewsEntity.Remove(model);
PE.SaveChanges();
return RedirectToAction("News");
}

 

小弟刚接触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。
