示例1: BroadcastEvent

        ///     Broadcast the Loaded/Unloaded event in the sub-tree starting at the given root
        /// </summary>
        /// <param name="root">
        ///     Root of the sub-tree that the event will be broadcast to
        /// </param>
        /// <param name="routedEvent">
        ///     RoutedEventID for the event we wish to broadcast
        /// </param>
        private static void BroadcastEvent(DependencyObject root, RoutedEvent routedEvent)
        {
            // Broadcast to the tree and collect the set of nodes
            // on which we need fire the Loaded event
            List<DependencyObject> eventRoute = new List<DependencyObject>();

            // Create a DescendentsWalker for the broadcast
            DescendentsWalker<BroadcastEventData> walker = new DescendentsWalker<BroadcastEventData>(
                TreeWalkPriority.VisualTree, BroadcastDelegate, new BroadcastEventData(root, routedEvent, eventRoute));

            // Start the walk down
            walker.StartWalk(root);

            // Iterate and raise the event on each of the nodes in the tree
            for (int i=0; i< eventRoute.Count; i++)
