我有一个滑块。当我设置它的高度时，选择边框会发生变化，但滑块高度仍然相同（22px）。
这是一个屏幕截图：
我相信我需要更改默认样式的一些属性，但我不明白什么 - 我想让高度动态 - 如果我更改为 200 它将是 200，如果我更改为 158 它将是 158 等等。 ..
我通过更改特定高度成功将高度更改HorizontalThumb Height为特定高度（更改为与我设置的高度不同的高度）

好的，我得到了你想要的。当您增加滑块本身的高度时，您也想增加轨道高度。然后您需要自定义滑块。我替换{StaticResource SliderTrackThemeHeight}为{TemplateBinding Height}，所以当滑块的高度增加时，滑块轨道也会增加。

用法
<Slider Height="72" VerticalAlignment="Center" HorizontalAlignment="Center" Width="500" Style="{StaticResource MyCustomSlider}"/>
滑块的轨道高度通过标准样式和资源分配。它的键是SliderTrackThemeHeight，默认值是 11。所以你只需要在下面写下一行App.xaml，只要你想改变它，你就可以访问资源并改变它。
<x:Double x:Key="SliderTrackThemeHeight">50</x:Double>
您可以像这样从后面的代码中设置。
Application.Current.Resources["SliderTrackThemeHeight"] = YOUR_DYNAMIC_VALUE;
