I've found a blog post by David Padburyfrom 2008 which goes into this and how to change it from code. Basically you override the meta data properties which merges in your changes to the existing values.
我在2008 年找到了David Padbury的一篇博客文章，其中介绍了这一点以及如何从代码中更改它。基本上，您覆盖了元数据属性，这些属性合并了您对现有值的更改。
TextElement.FontFamilyProperty.OverrideMetadata(
typeof(TextElement),
new FrameworkPropertyMetadata(
new FontFamily("Comic Sans MS")));
TextBlock.FontFamilyProperty.OverrideMetadata(
typeof(TextBlock),
new FrameworkPropertyMetadata(
new FontFamily("Comic Sans MS")));
There's also this MSDN forum postwhich explains how to do it in XAML in two ways.
还有这个MSDN 论坛帖子，它解释了如何以两种方式在 XAML 中执行此操作。
1) Firstly you define a "global" style for the Controlclass
1）首先你为Control类定义一个“全局”样式
<Style TargetType="{x:Type Control}">
<Setter Property="FontFamily" Value="Constantia"/>
</Style>
and then use the BasedOnproperty to apply that to other controls.
然后使用该BasedOn属性将其应用于其他控件。
<StackPanel xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<StackPanel.Resources>
<Style TargetType="{x:Type Control}" x:Key="ControlStyle">
<Setter Property="FontFamily" Value="Constantia"/>
</Style>
<Style TargetType="{x:Type Label}" x:Key="LabelStyle" BasedOn="{StaticResource ControlStyle}">
<Setter Property="FontWeight" Value="Bold" />
</Style>
<Style TargetType="{x:Type Button}" x:Key="ButtonStyle" BasedOn="{StaticResource ControlStyle}">
<Setter Property="Background" Value="Blue"/>
</Style>
</StackPanel.Resources>
<Label Style="{StaticResource LabelStyle}">This is a Label</Label>
<Button Style="{StaticResource ButtonStyle}">This is a Button</Button>
</StackPanel>
2) You can set the system fonts:
2）您可以设置系统字体：
<FontFamily x:Key="{x:Static SystemFonts.MenuFontFamilyKey}">./#Segoe UI</FontFamily>
<System:Double x:Key="{x:Static SystemFonts.MenuFontSizeKey}">11</System:Double>
<FontWeight x:Key="{x:Static SystemFonts.MenuFontWeightKey}">Normal</FontWeight>
Though I probably wouldn't recommend this.
虽然我可能不会推荐这个。

<Application.Resources>
<Style x:Key="WindowStyle" TargetType="{x:Type Window}">
<Setter Property="FontFamily" Value="PalatineLinoType" />
</Style>
</Application.Resources>
