Retrieves the top-level node of the current site map data structure.
Syntax
protected override SiteMapNode GetRootNodeCore ()
Returns
A System.Web.SiteMapNode that represents the top-level node in the current site map data structure.
Remarks
The XmlSiteMapProvider.GetRootNodeCore method calls the XmlSiteMapProvider.BuildSiteMap method to retrieve the top-level node in the site map. Therefore, any exceptions that occur for the XmlSiteMapProvider.BuildSiteMap method can also occur when calling the XmlSiteMapProvider.GetRootNodeCore method.
