<configuration>

<connectionStrings>

<add name="ConnStr" connectionString="Data Source=127.0.0.1;Initial Catalog=beta;Persist Security Info=True;User ID=sa;Password=123456"/>

</connectionStrings>

1、先在"引用"中添加System.configuration的引用
2、读取string ConnStr = ConfigurationManager.ConnectionStrings["ConnStr"].ConnectionString;
