Exemples

Cet exemple montre comment spécifier des valeurs de manière déclarative pour plusieurs attributs de la siteMap section, qui sont également accessibles en tant que membres de la SiteMapSection classe.

L’exemple de fichier de configuration suivant montre comment spécifier des valeurs de manière déclarative pour la siteMap section.

<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>
