調用：

 List<ScrollBar> scrollBarList = GetVisualChildCollection<ScrollBar>(listBox1);            foreach (ScrollBar scrollBar in scrollBarList)            {                if (scrollBar.Orientation == System.Windows.Controls.Orientation.Horizontal)                {                }                else                {                    scrollBar.ValueChanged += new RoutedPropertyChangedEventHandler<double>(verticalScrollBar_ValueChanged);                }            }
