In order to use StaticResource, the style has to be defined before the element you are trying to apply it to within the same visual tree.
为了使用StaticResource，必须在您尝试将其应用于同一可视树中的元素之前定义样式。
You could add your resource dictionary to a control's resources above the button in the visual tree
您可以将资源字典添加到可视化树中按钮上方的控件资源中
<Window x:Class="StackOverflow.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525">
<Window.Resources>
<ResourceDictionary Source="ButtonStyle.xaml"/>
</Window.Resources>
<Grid>
<Button Click="ButtonBase_OnClick" Style="{StaticResource CloseButton}">Click</Button>
</Grid>
or instead you could use DynamicResource, which does not require the style to be at the same level or above in the visual tree.
或者，您可以使用DynamicResource，它不需要样式在可视化树中处于同一级别或更高级别。
<Button Click="ButtonBase_OnClick" Style="{DynamicResource CloseButton}">Click</Button>

XAML is cached. VS locks it when you have the *.xaml and *xaml.cs files open. Close them in Visual Studio and you may see the problem go away.
XAML 被缓存。当您打开 *.xaml 和 *xaml.cs 文件时，VS 会锁定它。在 Visual Studio 中关闭它们，您可能会看到问题消失。
