is the root node of the XmlSiteMapProvider.
Remarks
The node
parameter is added to an internal collection, and a parent/child relationship is created between it and parentNode
.
The XmlSiteMapProvider class, derived from the StaticSiteMapProvider class and the default site map provider for ASP.NET, uses the Url property of a SiteMapNode object as a lookup key in its internal collections, by default. If the Url property of the SiteMapNode is set, it must be unique within the scope of the provider. The FindSiteMapNode method attempts to retrieve nodes based on their Url. Otherwise, you can use the Key property, and the corresponding FindSiteMapNodeFromKey method, to retrieve nodes.
