ArrayList list = new ArrayList();for (int k = 0; k < 6; k++){for (int p = 0; p < 11; p++){Label labs = new Label();labs.HorizontalAlignment = HorizontalAlignment.Left;labs.VerticalAlignment = VerticalAlignment.Top;labs.Margin = new Thickness(599 + (17 * p), 206 + (17 * k), 0, 0);labs.Name = "lab" + k + p;labs.Width = 16;labs.Height = 16;list.Add(labs);main.Children.Add(labs);}}我動態添加一些Label，并放入ArrayList中，后面我要遍歷ArrayList，獲取每個Label的值，對每個Label進行操作，要怎么寫？
