The "default" font is the current system font of your current OS. Tahoma is the default system font of Windows XP, on Vista, Windows 7 it is Segoe UI.
“默认”字体是当前操作系统的当前系统字体。Tahoma 是 Windows XP 的默认系统字体，在 Vista、Windows 7 上是 Segoe UI。

On Windows 8, it seems like the fallback font is Segoe UI with a 0.9 baseline and 1.2 line spacing.
在 Windows 8 上，后备字体似乎是 Segoe UI，基线为 0.9，行距为 1.2。

You can take it from default value of DependencyProperty. For example, you create custom control, which will be draw text using DrawingContext and you want set default value for FontFamily, you can declare DependencyPropertysuch way:
您可以从 的默认值中获取它DependencyProperty。例如，您创建自定义控件，它将使用 DrawingContext 绘制文本，并且您想为 FontFamily 设置默认值，您可以DependencyProperty这样声明：
public static readonly DependencyProperty FontFamilyProperty = DependencyProperty.Register(nameof(FontFamily), typeof(FontFamily), typeof(MyControl), new FrameworkPropertyMetadata(TextBlock.FontFamilyProperty.DefaultMetadata.DefaultValue, FrameworkPropertyMetadataOptions.AffectsRender));
public FontFamily FontFamily
{
get => (FontFamily)GetValue(FontFamilyProperty);
set => SetValue(FontFamilyProperty, value);
}
