ADO.NET連接SQL2000

EF4.0連接SQL2000

一、建立一個空的Web運用程式

二、添加新建項目，選擇ADO.NET實體數據模型，改名為MyModel.edmx,

三、選擇空模型，完成

四、將MyModel.edmx以記事本的形式打開，並將用（http://www.skonet.com/uploadedFiles/Code/BaseEntityModel.edmx.xml ）xml文件內容替換。並Ctrl+F把所有%DB_NAME% 替换成MyModel，共6处替换，替换完成后保存关闭该页，不关闭后面可能会出问题。

五、在项目中新建一个配置文件web.config，把以下配置节复制到web.config，

    <connectionStrings>

   <add name="%DB_NAME%Entities" connectionString="metadata=res://*/%DB_NAME%.csdl|res://*/%DB_NAME%.ssdl|res://*/%DB_NAME%.msl;provider=System.Data.SqlClient;providerconnection string="Data Source=%DB_HOST_NAME%;InitialCatalog=%DB_NAME%;Persist Security
Info=True;UserID=%DB_USER%;Password=%DB_USER_PWD%;MultipleActiveResultSets=False"" providerName="System.Data.EntityClient" />

  </connectionStrings>

六、把配置中的所有%DB_NAME%替换成MyModel，共5处替换，修改%DB_HOST_NAME%为你的数据库实例名。

七.Initial Catalog=%DB_NAME% 这里的%DB_NAME% 改成你要连接的库的名稱。

八、雙擊直接打開MyModel.edmx計設視圖模式打開，右擊選擇從數據庫更新模型。

九、同樣支持添加代碼生成項

整個項目就是這樣的
