在xaml中，我应该如何/在哪里放置一个部分，以便不会为每个标签复制托盘图标？

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

    <Style x:Key="TrayIconStyle" TargetType="Button">
        <!-- 定义托盘图标的样式 -->
        <!-- ... -->
    </Style>

</ResourceDictionary>

<Window x:Class="YourNamespace.YourWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:local="clr-namespace:YourNamespace"
        Title="Your Window" Height="450" Width="800">

    <Window.Resources>
        <!-- 引用资源字典文件 -->
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="SharedResources.xaml"/>
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </Window.Resources>

    <Grid>
        <!-- 在需要的地方使用托盘图标 -->
        <Button Style="{StaticResource TrayIconStyle}" Content="Tray Icon"/>
    </Grid>

</Window>
