等待0.1秒直至隐藏图像(Waiting .1 second until hiding an ima

我在C＃中做一个小程序，Windows Phone的。 有一两件事，它应该做的是隐藏按钮的工具栏，只要用户点击“隐藏”按钮。

我已经完成了代码隐藏工具栏。 它隐藏的按钮，如预期。 但就现在的情况是，所有的按钮消失一次。 为了使一种“动漫”的，我已经决定要等到0.1秒直到隐藏所有的按钮。

我怎么会等待0.1秒？

这里是我的代码现在。

    bool panelopened = false;

    private void image1_MouseEnter(object sender, MouseEventArgs e)
    {
        if (panelopened == false)
        {
            ImageSourceConverter imgs = new ImageSourceConverter();
            image1.SetValue(Image.SourceProperty, imgs.ConvertFromString("/Main%20View;component/Images/hide.png"));
            image3.Width = 50;
            image4.Width = 50;
            image5.Width = 50;
            panelopened = true;
        }
        else
        {
            ImageSourceConverter imgs = new ImageSourceConverter();
            image1.SetValue(Image.SourceProperty, imgs.ConvertFromString("/Main%20View;component/Images/more.png"));
            image3.Width = 0;
            image4.Width = 0;
            image5.Width = 0;
            panelopened = false;
        }
    }

你这样做的方式不是最好 - 在UI线程很多OD工作。

我在我的应用程序下面的代码使用。 Remeber，Sroryboards动画合成器上的螺纹轻量且execly专为这一目的运行。

// fade animation of the Popup to opacity 1.0
    private void ShowPopup()
    {
        exitPopup.Visibility = Visibility.Visible;
        Storyboard storyboard = new Storyboard();
        DoubleAnimation fadeAnimation = new DoubleAnimation();
        fadeAnimation.To = 1;
        fadeAnimation.Duration = TimeSpan.FromSeconds(1);
        //fadeAnimation.FillBehavior = FillBehavior.Stop;
        StoryBoardHelper.SetTarget(fadeAnimation, exitPopup);
        Storyboard.SetTargetProperty(fadeAnimation, new PropertyPath("(Canvas.Opacity)"));
        storyboard.Children.Add(fadeAnimation);
        storyboard.Duration = fadeAnimation.Duration;
        storyboard.Begin();
    }

    // fade aninmation to opacity 0.0
    private void ClosePopup()
    {
        Storyboard storyboard = new Storyboard();
        DoubleAnimation fadeAnimation = new DoubleAnimation();
        fadeAnimation.To = 0;
        fadeAnimation.Duration = TimeSpan.FromSeconds(0.2);
        //fadeAnimation.FillBehavior = FillBehavior.Stop;
        StoryBoardHelper.SetTarget(fadeAnimation, exitPopup);
        Storyboard.SetTargetProperty(fadeAnimation, new PropertyPath("(Canvas.Opacity)"));
        storyboard.Children.Add(fadeAnimation);
        storyboard.Duration = fadeAnimation.Duration;
        storyboard.Begin();
        storyboard.Completed += (sender, e) => exitPopup.Visibility = Visibility.Collapsed;
    }

你需要一两件事。 设置的BeginTime开始动画形式1S。

您随时可以将此代码更改为XAML是更小，更explicite。

看看这个以前的答案 。 使用这个你可以做

Dispatcher.DelayInvoke(TimeSpan.FromSeconds(0.1), () => 
{
   image3.Width = 0;
   image4.Width = 0;
   image5.Width = 0;
}
