Asp.Net2.0 配置文件之connectionStrings用法收藏

以前写Asp.net代码，用的Web.Config配置文件中连接字符串多是

         <appSettings>
           <add key="ConnectionString"  value="Server=.;Integrated Security=SSPI;Database=Message;" />
         </appSettings> 

        在Asp.Net 2.0  中新加了<connectionStrings>这一节

       <connectionStrings > 
          <add />
          <clear />
          <remove />
       </connectionStrings>

        现在用起来就方便些了

       <connectionStrings>

         <add name="Sales"
              providerName="System.Data.SqlClient"
              connectionString= "server=myserver;database=Products;uid=salesUser;pwd=sellMoreProducts" />

       </connectionStrings>

         使用时，只需要如下即可：

        System.Configuration.ConfigurationManager.ConnectionStrings["Sales"]
