比较简单的一个小功能，和新毒霸类似的效果。

效果代码：

bool closeStoryBoardCompleted = false;
DoubleAnimation closeAnimation1;
void closeWindow_Completed(object sender, EventArgs e)
{
closeStoryBoardCompleted = true;
this.Close();
}
private void Window_Closing(object sender, System.ComponentModel.CancelEventArgs e)
{
if (!closeStoryBoardCompleted)
{
closeAnimation1 = new DoubleAnimation();
closeAnimation1.From = ; //初始值 1为整个窗体 0.1表示窗体的十分之一
closeAnimation1.To = ; //结束值 0为完全关闭
closeAnimation1.Duration = new Duration(TimeSpan.Parse("0:0:0.3")); //所用时间的间隔
closeAnimation1.Completed += new EventHandler(closeWindow_Completed);
ScaleTransform st = new ScaleTransform(); st.CenterY = this.Height / ; //以纵向的方式缩小
this.RenderTransform = st;
st.BeginAnimation(ScaleTransform.ScaleYProperty, closeAnimation1);
e.Cancel = true;
}
}
