我有最困难的时间来解决这个问题：说我有两个Button和三个TextBlocks。我想要任一按钮在所有TextBlocks上触发一个简单的故事板。目前我正在尝试定义包含Storyboard的通用Textblock样式，然后触发器来自任何Button单击。这是我最接近的但应用程序在启动时崩溃了......我在这里没有错：
<Window.Resources>
<Style TargetType="TextBlock" >
<Setter Property="Foreground" Value="Blue" />
<Style.Resources>
<Storyboard x:Key="TextBlockOpacity" Storyboard.TargetProperty="Opacity">
<DoubleAnimation From="0" To="1" />
</Storyboard>
</Style.Resources>
</Style>
<Window.Triggers>
<EventTrigger RoutedEvent="ButtonBase.Click" SourceName="button">
<BeginStoryboard Storyboard="{StaticResource TextBlockOpacity}"/>
</EventTrigger>
</Window.Triggers>
<Grid x:Name="LayoutRoot">
<Button x:Name="button" HorizontalAlignment="Left" Margin="51,54,0,0" VerticalAlignment="Top" Width="96" Height="45" Content="Button"/>
<TextBlock x:Name="textBlock1" Margin="228,54,172,0" VerticalAlignment="Top" Height="45" FontSize="26.667" Text="TextBlock" TextWrapping="Wrap" />
<TextBlock x:Name="textBlock2" Margin="228,103,172,0" VerticalAlignment="Top" Height="45" FontSize="26.667" Text="Hello" TextWrapping="Wrap"/>
</Grid>

如果您“专用”按钮来更改不透明度，则可以利用其DataContext并为其设置动画。然后只需将元素“Opacity绑定到DataContext：
（我还重构了你的xaml）
<Window x:Class="SomeNamespace.Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:System="clr-namespace:System;assembly=mscorlib"
Title="Window1" Height="300" Width="300">
<Window.Resources>
<Storyboard x:Key="TextBlockOpacity" Storyboard.TargetName="button1" Storyboard.TargetProperty="DataContext" >
<DoubleAnimation From="0.1" To="1"/>
</Storyboard>
<Style TargetType="TextBlock" >
<Setter Property="Foreground" Value="Blue" />
<Setter Property="Background" Value="LightGray" />
<Setter Property="FontSize" Value="26.667" />
<Setter Property="TextWrapping" Value="Wrap" />
<Setter Property="Height" Value="45" />
<Setter Property="Opacity" Value="{Binding ElementName=button1, Path=DataContext}"/>
</Style>
</Window.Resources>
<Window.Triggers>
<EventTrigger RoutedEvent="ButtonBase.Click">
<BeginStoryboard Storyboard="{StaticResource TextBlockOpacity}" >
</BeginStoryboard>
</EventTrigger>
<EventTrigger RoutedEvent="ListBox.SelectionChanged">
<BeginStoryboard Storyboard="{StaticResource TextBlockOpacity}" >
</BeginStoryboard>
</EventTrigger>
</Window.Triggers>
<Grid x:Name="LayoutRoot">
<Button x:Name="button1" HorizontalAlignment="Left" Margin="51,54,0,0" VerticalAlignment="Top" Width="96" Height="45" Content="Button">
<Button.DataContext>
<System:Double>0</System:Double>
</Button.DataContext>
</Button>
<Button x:Name="button2" HorizontalAlignment="Right" Margin="0,54,29,0" VerticalAlignment="Top" Width="96" Height="45" Content="Button"/>
<ListBox x:Name="listBox1" Height="50" VerticalAlignment="Top">
<ListBox.Items>
<System:String>Text1</System:String>
<System:String>Text2</System:String>
</ListBox.Items>
</ListBox>
<TextBlock x:Name="textBlock1" Margin="51,114,61,0" Text="TextBlock" Height="45" VerticalAlignment="Top" Width="166" />
<TextBlock x:Name="textBlock2" Margin="51,0,74,42" Text="Hello" Height="45" Width="153" VerticalAlignment="Bottom" />
</Grid>
</Window>
还要注意一件事 - 如果你想最小化你的代码，这是使用的方法，和让它在xaml中发生。你的方法会使整个Window的Opacity失效。这就是为什么在上面的代码中，TextBlocks绑定到按钮的DataContext，它本身就是动画的。
当然没有绑定到公共值（DataContext）是可行的，但是你需要重复X动画（因为你需要设置X TargetNames）。上述方法更容易扩展和维护。
修改
添加了另一个Button和一个ListBox用于变种：）

基于kek444的Xaml-only解决方案，我提出了一个稍微改进的版本，它不依赖于按钮的DataContext，并且可以有多个触发器。
<Window
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
x:Class="WpfApplication1.MainWindow"
x:Name="Window"
Title="MainWindow"
Width="640" Height="480">
<Window.Resources>
<UIElement x:Key="OpacityCounter" Opacity="0"/>
<Style TargetType="TextBlock">
<Setter Property="Opacity" Value="{Binding Source={StaticResource OpacityCounter}, Path=Opacity}" />
</Style>
<Storyboard x:Key="OnClick1">
<DoubleAnimationUsingKeyFrames BeginTime="00:00:00" Storyboard.Target="{StaticResource OpacityCounter}" Storyboard.TargetProperty="(UIElement.Opacity)">
<SplineDoubleKeyFrame KeyTime="00:00:00" Value="0"/>
<SplineDoubleKeyFrame KeyTime="00:00:00.5000000" Value="1"/>
</DoubleAnimationUsingKeyFrames>
</Storyboard>
</Window.Resources>
<Window.Triggers>
<EventTrigger RoutedEvent="ButtonBase.Click" SourceName="button1">
<BeginStoryboard Storyboard="{StaticResource OnClick1}"/>
</EventTrigger>
<EventTrigger RoutedEvent="ButtonBase.Click" SourceName="button2">
<BeginStoryboard Storyboard="{StaticResource OnClick1}"/>
</EventTrigger>
</Window.Triggers>
<Grid x:Name="LayoutRoot">
<StackPanel>
<StackPanel Orientation="Horizontal">
<Button x:Name="button1" Width="131" Height="37" Content="Button 1" Margin="0,0,0,22"/>
<Button x:Name="button2" Width="131" Height="37" Content="Button 2" Margin="0,0,0,22"/>
</StackPanel>
<TextBlock x:Name="textBlock" Height="27" Text="TextBlock 1" TextWrapping="Wrap" />
<TextBlock x:Name="textBlock1" Height="27" Text="TextBlock 2" TextWrapping="Wrap" />
<TextBlock x:Name="textBlock2" Height="27" Text="TextBlock 3" TextWrapping="Wrap" />
<TextBlock x:Name="textBlock3" Height="27" Text="TextBlock 4" TextWrapping="Wrap" />
</StackPanel>
</Grid>
</Window>
要使用ListBox作为触发器机制（如果您在某个地方有一个名为“listbox1”的ListBox，请将以下内容添加到Window.Triggers：
<EventTrigger RoutedEvent="Selector.SelectionChanged" SourceName="listbox1">
<BeginStoryboard Storyboard="{StaticResource OnClick1}"/>
</EventTrigger>
或触发特定的ListBoxItem，你需要（其中item1是一个名为ListBoxItem）：
<EventTrigger RoutedEvent="ListBoxItem.Selected" SourceName="item1">
<BeginStoryboard Storyboard="{StaticResource OnClick1}"/>
</EventTrigger>

在您的示例中，您将样式中的Storyboard定义为资源，但之后您尝试将其作为Window资源进行访问。尝试将Storyboard声明移动到Window.Resources，然后引用样式中的Storyboard。
我不知道它是否会做你想要的，但我会从那里开始。
