.net2.0 中自己定义配置的实现

   实现web.config中的自定义如下配置:
  <?xml version="1.0"?>
<!--
    注意: 除了手动编辑此文件以外，您还可以使用
    Web 管理工具来配置应用程序的设置。可以使用 Visual Studio 中的
     “网站”->“Asp.Net 配置”选项。
    设置和注释的完整列表在
    machine.config.comments 中，该文件通常位于
    \Windows\Microsoft.Net\Framework\v2.x\Config 中
-->
<configuration>
 <configSections>
  <sectionGroup name="gyzs.net" type="ComponentSectionGroup">
     <section name="security" type="SecuritySection"/>
  </sectionGroup>
 </configSections>
...............
<system.web>
..............
</system.web>
 <gyzs.net>
  <security configSource="config\security.config" />
 </gyzs.net>
</configuration>

config\security.config 文件内容如下
<?xml version="1.0" encoding="utf-8"?>
<!-- 注意: 除了手动编辑此文件以外，您还可以使用 Web 管理工具来
     配置应用程序的设置。可以使用 Visual Studio 中的“网站”->“ASP.NET 配置”
     选项。
     设置和注释的完整列表在
     machine.config.comments 中，该文件通常位于 \Windows\Microsoft.NET\Framework\v2.0.xxxxx\Config 中
 -->
<security enabled="true">
 <checkPermissionPages mode="Windows">
  <page url="AdminUser.aspx" operateCode="Del" checkType="or"/>
  <page url="AdminUser2.aspx" operateCode="Add" checkType="or"/>
  <page url="AdminUser3.aspx" operateCode="Modify" checkType="or"/>
 </checkPermissionPages>
</security>
