关于wpf动画问题？

Question

我在xaml中写一段动画，然后在事件触发中这样写可以触发事件：
        <EventTrigger SourceName="button1" RoutedEvent="Button.Click">
            <BeginStoryboard Name="closeQueryCanvasStoryboard" 
                      Storyboard="{StaticResource 动画名}">
            </BeginStoryboard>
        </EventTrigger>
以上代码可以实现当button1单击时播放动画。
我现在的为问题是：如何在程序的运行过程中由代码自动触发动画呢，比如在程序执行过程中根据代码中的某一变量n是否等于10来确定是否播放动画，每当n从1加到10的时候就播放一次动画。

Answer 1

if (n == 10)
    closeQueryCanvasStoryboard.begin();

Answer 2

closeQueryCanvasStoryboard.begin();编译都不过，代码中不认closeQueryCanvasStoryboard

Answer 3

public partial class Window1 : Window
    {
        private Storyboard myStoryBoard;         public Window1()
        {
            InitializeComponent();            this.RegisterName("TestButton1", TestButton1);
            DoubleAnimation da = new DoubleAnimation();
            da.From = 1.0;
            da.To = 0.0;
            myStoryBoard = new Storyboard();
            myStoryBoard.Children.Add(da);
            Storyboard.SetTargetName(da, "TestButton1");
            Storyboard.SetTargetProperty(da, new PropertyPath(Button.OpacityProperty));
        }        private void TestButton_Click(object sender, RoutedEventArgs e)
        {
            myStoryBoard.Begin(this, true);
        }
    }Xmal里新建一个button叫TestButton1就可以了

我这么试的一个，在后台调用好使，你试着改改。
挺长时间不用，有点忘了。
txttt.Begin();<Rectangle Name="MyRectangle" Width="100" Height="100">
            <Rectangle.Fill>
                <SolidColorBrush x:Name="MySolidColorBrush" Color="Blue" />
            </Rectangle.Fill>
            <Rectangle.Triggers>
                <EventTrigger RoutedEvent="Page.Loaded">
                    <BeginStoryboard>
                        <Storyboard x:Name="txttt" RepeatBehavior="Forever" AutoReverse="True">
                            <DoubleAnimation 
                                Storyboard.TargetName="MyRectangle"
                                Storyboard.TargetProperty="Width"
                                From="100" To="200" Duration="0:0:1" />
                                            <ColorAnimation 
                                Storyboard.TargetName="MySolidColorBrush"
                                Storyboard.TargetProperty="Color"
                                From="Blue" To="Red" Duration="0:0:1" />
                        </Storyboard>
                    </BeginStoryboard>
                </EventTrigger>
            </Rectangle.Triggers>
        </Rectangle>

在后台代码获取指定的 Storyboard，手动调用Begin 方法
或者样式表中设置 dataTrigger
