xaml styles Is there a way to specify fontsize to one of 5 values?

Question

I would like to be able to support 5 sizes, verysmall, small, normal, large, verylarge.

is there a smart way to do that with styles? < fontsize={DynamicResourec Small}"/>

where I define small somewhere else?

• I am aware that i could just write 18, insstead, but I might want to scale the fonts later...

Here is a complete example with .Net 5 where the resource is in MainWindow.

<Window x:Class="WpfNet5.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    xmlns:local="clr-namespace:WpfNet5"
    xmlns:system="clr-namespace:System;assembly=System.Runtime"
    mc:Ignorable="d"
    Title="MainWindow" Height="450" Width="800">
<Window.Resources>
    <system:Double x:Key="VerySmall">12</system:Double>
    <system:Double x:Key="Small">18</system:Double>
    <system:Double x:Key="Medium">22</system:Double>
    <system:Double x:Key="Large">26</system:Double>
</Window.Resources>

  <Grid>
      <StackPanel >
          <TextBlock Text="Very small" FontSize="{DynamicResource VerySmall}"/>
          <TextBlock Text="Small" FontSize="{DynamicResource Small}"/>
          <TextBlock Text="Medium" FontSize="{DynamicResource Medium}"/>
          <TextBlock Text="Large" FontSize="{DynamicResource Large}"/>
      </StackPanel>
  </Grid>
</Window>
