我使用fluentribbon和mahapps作为我的 GUI，并希望在我的功能区中有一个带有图标的按钮。我想用XAML的图标，如本（而不是一个文件）。所以我需要在 fluent:Button 中设置 Path。我尝试了以下但它不工作 - 按钮是空白的（没有文字和图标显示）：

<fluent:Button Name="Test">
    <StackPanel VerticalAlignment="Stretch" HorizontalAlignment="Center">
        <Path Width="40" Height="40" Stretch="Uniform" UseLayoutRounding="False" Fill="Black" Data="..."/>
        <TextBlock><Run Text="Test Button"/></TextBlock>
    </StackPanel>
</fluent:Button>

更新

这是完整的代码：
