回答：

感谢Justin XL，我能够解决我的问题。

我在他的回答中实现了他在下面提供的样式，并在 App.xaml 中添加了他所说的：（我将高度更改为 66 - 更适合我）

<Application.Resources>
        <x:Double x:Key="AppBarThemeCompactHeight">66</x:Double>
    </Application.Resources>

然后在我的CommandBar

Height="{StaticResource AppBarThemeCompactHeight}"

问题：

我希望我的命令栏始终以标准模式显示其标签。我有辅助命令，所以IsOpen=true不是我的选择。

在此处输入图像描述

现在我只看到图标，下面没有标签。

命令栏的官方 Microsoft 网站是这样说的：

应用栏按钮控件的特点是图标和相关标签。它们有两种尺寸；正常而紧凑。默认情况下，显示文本标签。当 IsCompact 属性设置为 true 时，文本标签被隐藏。在 CommandBar 控件中使用时，命令栏会在命令栏打开和关闭时自动覆盖按钮的 IsCompact 属性。

这有点问题。有什么想法可以让我IsCompact=False工作吗？

这可以通过编辑AppBarButton.

工作演示

首先，使用 Blend 生成默认样式，然后找到Compact视觉状态并将Visibility目标值形式更改Collapsed为Visible. 这样，无论IsCompact值是什么，标签都将始终可见。
