你有选择的图片。如果我们看看Flyout Style Template的胆量，我们注意到一些设置为Padding和Border的主题资源，您可以使用它们覆盖这些属性，或者仅为Flyout创建自己的Style模板，然后让它们成为您喜欢的任何内容。

因此，例如，如果您将类似这样的东西扔到您的资源字典中，则应该覆盖该应用程序的ThemeResource。

<Thickness x:Key="FlyoutContentThemePadding">0,0,0,0</Thickness> 
<Thickness x:Key="FlyoutBorderThemeThickness">0</Thickness>

希望这会有所帮助，欢呼！
