Xaml 如何定制亚克力刷

我想用亚克力刷子刷烟囱面板的表面

<StackPanel Background="{ThemeResource SystemControlAcrylicElementBrush}"></StackPanel>

这对我来说是可行的，但当我想改变色调和不透明度时，会出现问题。有以下代码可对其进行更改：

<ResourceDictionary.ThemeDictionaries>
<ResourceDictionary x:Key="Default">
    <AcrylicBrush x:Key="MyAcrylicBrush"
        BackgroundSource="HostBackdrop"
        TintColor="#FFFF0000"
        TintOpacity="0.8"
        FallbackColor="#FF7F0000"/>
</ResourceDictionary>

我不知道我应该把它放在哪里，并为此重命名笔刷

 <StackPanel Background="{ThemeResource **MyAcrylicBrush**}"></StackPanel>

谢谢你的帮助。 另外，您需要Windows Insider SDK和system build 16190或更高版本

您可以创建一个ResourceDictionary，例如名为ThemeDictionary.xaml的，并将您的AcrylicBrush代码放在其中

然后在App.xaml中，您可以像这样引用您的ResourceDictionary：

方法1： 在Application.Resources中添加ResourceDictionary.Themedictionary

在App.xaml中

您可以在App.xaml中合并ResourceDictionary文件

请将其放在App.xaml中

<Application.Resources>
  <ResourceDictionary>
    <ResourceDictionary.MergedDictionaries>
      <ResourceDictionary Source="ThemesDictionary.xaml" />
    </ResourceDictionary.MergedDictionaries>
  </ResourceDictionary>
</Application.Resources>

<Application.Resources>
    <ResourceDictionary>
        <ResourceDictionary.ThemeDictionaries>

            </ResourceDictionary>

            <ResourceDictionary x:Key="HighContrast">
                <SolidColorBrush x:Key="MyAcrylicBrush" Color="{ThemeResource SystemColorWindowColor}"/>
            </ResourceDictionary>

            <ResourceDictionary x:Key="Light">
