WPF全局动画控制

WPF写的全局动画控制，鼠标移上去会改变Ellipse的颜色，可以用checkbox取消动画显示。

效果如图：

1.新建wpf项目，新建一个文件夹，命名为：Res，在里面添加两个资源字典，分别命名为：Dictionary1.xaml和Dictionary2.xaml；

2.添加一个wpf窗体，命名为：MainWindow；

3.Dictionary2.xaml代码：

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
	<Storyboard x:Key="Storyboard1">
		<ColorAnimationUsingKeyFrames Storyboard.TargetProperty="(Shape.Fill).(SolidColorBrush.Color)" Storyboard.TargetName="rectangle">
			<EasingColorKeyFrame KeyTime="0:0:0.5" Value="Yellow"/>
		</ColorAnimationUsingKeyFrames>
	</Storyboard>
	<Storyboard x:Key="Storyboard2">
		<ColorAnimationUsingKeyFrames Storyboard.TargetProperty="(Shape.Fill).(SolidColorBrush.Color)" Storyboard.TargetName="rectangle">
			<EasingColorKeyFrame KeyTime="0" Value="Yellow"/>
			<EasingColorKeyFrame KeyTime="0:0:0.5" Value="Red"/>
		</ColorAnimationUsingKeyFrames>
	</Storyboard>
</ResourceDictionary>

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
	<Storyboard x:Key="Storyboard1">
	</Storyboard>
	<Storyboard x:Key="Storyboard2">
	</Storyboard>
</ResourceDictionary>

namespace WPF动画控制 {

	public partial class App : Application {

		protected override void OnStartup(StartupEventArgs e) 
        {
			base.OnStartup(e);
			App.LoadResources(true);
		}

		public static void LoadResources(bool allowStoryboard) 
        {
            string resFilename = "/Res/" + (allowStoryboard ? "Dictionary2.xaml" : "Dictionary1.xaml");
			ResourceDictionary resDic = new ResourceDictionary {Source = new Uri(resFilename, UriKind.Relative)};
			Application.Current.Resources.MergedDictionaries.Clear();
			Application.Current.Resources.MergedDictionaries.Add(resDic);
		}
	}
}
