【.Net码农】【MVC】如何搭建MVC + EF 框架

http://blog.sina.com.cn/s/blog_3d25ef340101aozv.html

1、搭建MVC框架

   1.1 VS2010：需要安装安装WPI 安装 ASP.NET MVC 4 和Visual Studio 2010 系统必备组件

   如果上述链接无法打开，请访问：http://www.asp.net/mvc/tutorials/mvc-4/getting-started-with-aspnet-mvc4/intro-to-aspnet-mvc-4

   



    如果VS2010 创建Web项目时，出现ASP.NET MVC 4 Web Application ,说明组件安装成功。

 

   1.2 VS2012：无需安装任何组件

  

2、搭建EF框架

   2.1 创建一个数据库OumindBlog

    

USE [OumindBlog]

   2.2 用VS2010创建一个MVC程序

   

 

点击“确定”

 

选择 “Empty”

   2.3 创建OumindBlog.edmx文件

   路径：项目->添加新项

 

   

 

 

选择  数据 - ADO.NET 实体数据模型，然后把名称改为 OumindBlog

 

选中从数据库生成，点击下一步

 

把连接字符串名称改为 “BlogContext”

 

在红框中打勾

发现View文件夹下多了一个OumindBlog.edmx 文件

   2.4 添加 EntityFrame 程序包

  路径 ：项目 ->管理NuGet程序包

   

  

首先，需要从 NuGet 获取实体框架的最新版本。

• “项目”–>“管理 NuGet 程序包…”
  如果没有“管理 NuGet 程序包...”选项，则应安装 NuGet 的最新版本，

  如果链接无法打开，请访问：http://msdn.microsoft.com/zh-cn/data/jj206878 或者http://visualstudiogallery.msdn.microsoft.com/27077b70-9dad-4c64-adcf-c7cf6bc9970c

• 选择“联机”选项卡
• 选择“EntityFramework”程序包
• 单击“安装”

  

点击“安装”

 

  点击“我接受”


   

    安装已完成

 

     如果EF程序包已安装，再次打开安装，可以看到程序包右上角有个绿色的对勾，说明程序包已安装。
 

 

 

   2.5 添加 EF 5.x DbContext Generator for C# 模板

  

 

在 EF 设计器中，右键单击模型上的空位置，选择“添加代码生成项...”

 

选择“EF 5.x DbContext Generator for C#”，输入名称 OumindBlog，然后单击“添加”

 

从左侧菜单中选择“联机模板”，然后搜索“DbContext”





 添加完后，View文件夹下多了两个文件,一个是OumindBlog.Context.tt,另一个是OumindBlog.tt。

 搭建EF框架需要三个文件和两个组件

  A、三个文件：OumindBlog.Context.tt、OumindBlog.tt 和 OumindBlog.edmx

  B、两个组件：EntityFrame程序包 和 EF 5.x DbContext Generator for C#

 

 

3、编写代码 

 3.1 在编写代码前，增加一个控制器HomeControllers(HomeController.cs)和一个View(Index.cshtml)

 

把红框中的勾去掉

3.2 打开HomeController.cs

    

3.3 打开Views->Home->Index.cshtml

 

  

 

3.4 运行结果

 

在解决方案资源管理器中，选择MvcTest,点击“右键”，选中在浏览器中查看或者按快捷键 Ctrl + Shift + W
