示例
此示例演示如何为节的 siteMap 多个属性以声明方式指定值，该属性也可以作为类的成员 SiteMapSection 进行访问。
以下配置文件示例演示如何以声明方式为 siteMap 节指定值。
<system.web>
<siteMap defaultProvider="XmlSiteMapReader" enabled="true">
<providers>
<clear />
<add
name="XmlSiteMapReader"
type="XmlSiteMapProvider, System.Web, Version=1.1.3300.0,
Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"
siteMapFile="my.sitemap"
description="XmlSiteMapProvider that loads my.sitemap"/>
</providers>
</siteMap>
</system.web>
下面的代码示例演示如何使用该 SiteMapSection 类。
