SiteMapNodeCollection::SyncRoot Property
Gets an object that can be used to synchronize access to the collection.
Assembly: System.Web (in System.Web.dll)
Property Value
Type: System::ObjectAn object that can be used to synchronize access to the SiteMapNodeCollection.
Enumerating through a SiteMapNodeCollection collection is intrinsically not a thread safe procedure. Even when a SiteMapNodeCollection is synchronized, other threads can still modify the SiteMapNodeCollection, which causes the enumerator to throw an exception. To guarantee thread safety during enumeration, you can either lock the SiteMapNodeCollection during the entire enumeration or catch the exceptions resulting from changes that are made by other threads.
