Gets or sets the preferred top-level font family for the TextBlock.
Assembly: PresentationFramework (in PresentationFramework.dll)

[<LocalizabilityAttribute(LocalizationCategory.Font)>] member FontFamily : FontFamily with get, set
<object> <object.FontFamily> <FontFamily .../> </object.FontFamily> </object>
<object FontFamily="fontFamilyName"/> - or - <object FontFamily="fontFamilyNamesList"/> - or - <object FontFamily="fontFamilyFolderReference"/> - or - <object FontFamily="fontFamilyUriReference"/>
Any settings on child elements override this top-level setting.
When multiple families are specified, the second and subsequent font families serve as fallback families to be used in cases where the primary font family is unavailable or not applicable.
This dependency property also has an attached property usage. In XAML, the usage is <object ="value".../>, where object is an object element (typically a flow element) contained within a TextBlock, and value is one of the string-format values as explained in XAML Values. In code, the attached property usage is supported by GetFontFamily and SetFontFamily. The attached property usage is not common, because most elements that can be contained in a TextBlock support an analogous nonattached FontFamily property, which the TextBlock uses for rendering.
The following example shows how to set the attribute of a TextBlock element.
<TextBlock Name="textBlock" Background="AntiqueWhite" Foreground="Navy" FontFamily="Century Gothic" FontSize="12" FontStretch="UltraExpanded" FontStyle="Italic" FontWeight="UltraBold" LineHeight="Auto" Padding="5,10,5,10" TextAlignment="Center" TextWrapping="Wrap" Typography.NumeralStyle="OldStyle" Typography.SlashedZero="True" > <Run Background="LightGreen">Text run 1.</Run> <LineBreak/><Run Background="LightBlue">Text run 2.</Run> <LineBreak/><Run Background="LightYellow">Text run 3.</Run> </TextBlock>
The following example shows how to set the property programmatically.
