示例代码：

/**/ /*

            using Microsoft.Practices.EnterpriseLibrary.Common;
            using Microsoft.Practices.EnterpriseLibrary.Data;
            using Microsoft.Practices.EnterpriseLibrary.Data.Configuration;
            */

            DatabaseSettings dbSetting  =  ConfigurationManager.GetConfiguration( " dataConfiguration " )  as  DatabaseSettings;
            ConnectionStringData defaultConnection  =  dbSetting.ConnectionStrings[ 0 ];
            MessageBox.Show(defaultConnection.Parameters[ " database " ].Value);
            defaultConnection.Parameters[ " Integrated Security " ].Value  =   " True " ;
            defaultConnection.Parameters[ " database " ].Value  =   " 111 " ;
            defaultConnection.Parameters[ " server " ].Value  =   " 45345 " ;
            ConfigurationManager.WriteConfiguration( " dataConfiguration " , defaultConnection);
