   當我們要顯示一個控制項的時候，不僅僅要顯示這個控制項，還要有動畫的效果。

   主要用到了DoubleAnimation類。

 public static void ShowAnimation(object control)        {            Type type = control.GetType();            switch (type.Name)            {                case "Border":                    {                        Border newBorder = (Border)control;                        #region 高、寬變化動畫                        DoubleAnimation widthAnimation = new DoubleAnimation(0, newBorder.Width, new Duration(TimeSpan.FromSeconds(0.5)));                        newBorder.BeginAnimation(Border.WidthProperty, widthAnimation, HandoffBehavior.Compose);                        DoubleAnimation heightAnimation = new DoubleAnimation(0, newBorder.Height, new Duration(TimeSpan.FromSeconds(0.5)));                        newBorder.BeginAnimation(Border.HeightProperty, heightAnimation, HandoffBehavior.Compose);                        #endregion                    }                    break;                default:                    break;            }        }

調用的時候也簡單。

private void button_Click(object sender, RoutedEventArgs e)        {            bord1.Visibility = Visibility.Visible;            ShowAnimation(bord1);        }

效果如下：
