自定义配置节点configSections的使用

//App.config

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
 <configSections>
  <!--添加自定义配置节点,type：解析类名，程序集名-->
  <section name="PersonSetion" type="CommonConfig.PersonSectionHandler,CommonConfig"/>
 </configSections>
        <!--自定义节点内容-->
 <PersonSetion>
  <PersonInfo name="Name"  Value="Mr Lin" ReadOnly="true"></PersonInfo>
  <PersonInfo name="Department"  Value="Development" ReadOnly="true"></PersonInfo>
  <PersonInfo name="Position"  Value="Software Engineer" ReadOnly="true"></PersonInfo>
 </PersonSetion>
</configuration>
