web.config中两个连接数据库

web.config中两个连接数据库

 

<appSettings>
    <add key="dsfds" value="server=admin-pc;database=Northwind;User Id=sa;pwd="/>

</appSettings>

<connectionStrings>

<add name="ConnectionString" connectionString="Data Source=admin-pc;Initial Catalog=Northwind; User ID=sa;Password=" providerName="System.Data.SqlClient" />

</connectionStrings>

 

 

使用ConfigurationManager时需要引用 System.Configuration.dll

System.Configuration.ConfigurationManager.ConnectionStrings[1].ConnectionString.ToString() : //序号从1开始

System.Configuration.ConfigurationManager.AppSettings[0].ToString();//序号从0开始
