Exemplos

Este exemplo demonstra como especificar valores declarativamente para vários atributos da siteMap secção, que também podem ser acedidos como membros da SiteMapSection classe.

O exemplo seguinte do ficheiro de configuração mostra como especificar valores declarativamente para a siteMap secção.

<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>

O exemplo de código seguinte demonstra como usar a SiteMapSection classe.
