Assembly: System.Web (in System.Web.dll)
The property presumes that the site map provider implements its internal collections such that when a parent node retrieves its ChildNodes objects, the nodes are in the same order as they appear in the site map. If you use .NET Framework collection classes in an implementation of a SiteMapProvider provider, choose collections that implement the IList interface, such as the ArrayList or ListDictionary class. If you choose collections that do not implement the IList interface, such as the Hashtable class, unexpected results can occur for simple site navigation operations.
