.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>

测试代码 page_load事件

Configuration config = WebConfigurationManager.OpenWebConfiguration("/ajax/web.config");

ComponentSectionGroup group = config.GetSectionGroup("gyzs.net") as ComponentSectionGroup;

SecuritySection sec = group.SecuritySection;

foreach (PageElement page in sec.CheckPermissionPages.Pages)

{

Response.Write(page.Url + "<br>");

}

Response.Write(sec.CheckPermissionPages.Mode.ToString());
