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>
4.Dictionary1.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">
</Storyboard>
<Storyboard x:Key="Storyboard2">
</Storyboard>
</ResourceDictionary>
5.App.xaml.cs代码：
using System;
using System.Collections.Generic;
using System.Configuration;
using System.Data;
using System.Linq;
using System.Windows;
namespace WPF动画控制 {
/// <summary>
/// App.xaml 的交互逻辑
/// </summary>
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);
}
}
}
6.MainWindow.xaml代码：
<Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d"
x:Class="WPF动画控制.MainWindow"
Title="MainWindow" Height="196" Width="257">
<Window.Resources>
</Window.Resources>
<Window.Triggers>
<EventTrigger RoutedEvent="Mouse.MouseEnter" SourceName="rectangle">
<BeginStoryboard Storyboard="{DynamicResource Storyboard1}"/>
</EventTrigger>
<EventTrigger RoutedEvent="Mouse.MouseLeave" SourceName="rectangle">
<BeginStoryboard Storyboard="{DynamicResource Storyboard2}"/>
</EventTrigger>
</Window.Triggers>
<Grid>
<Ellipse x:Name="rectangle" HorizontalAlignment="Left" Margin="10,31,0,0" Stroke="Black" Width="117" Fill="#FFFF2800" Height="110" VerticalAlignment="Top" />
<CheckBox Content="动画效果" HorizontalAlignment="Left" Margin="10,10,0,0" VerticalAlignment="Top" IsChecked="True" Width="80" Click="CheckBox_Click" RenderTransformOrigin="0.338,0.75" />
</Grid>
</Window>
7.MainWindow.xaml.cs代码：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;
namespace WPF动画控制 {
/// <summary>
/// MainWindow.xaml 的交互逻辑
/// </summary>
public partial class MainWindow : Window {
public MainWindow() {
InitializeComponent();
}
private void CheckBox_Click(object sender, RoutedEventArgs e) {
CheckBox checkBox=sender as CheckBox;
App.LoadResources(checkBox.IsChecked.Value);
}
}
}
