在 wpf 中以编程方式更改字体系列

Question

我正在创建一个 WPF 应用程序。

我在我的解决方案中创建了一个文件夹，里面有一些字体。

如何以编程方式更改 TextBlock FontFamily ？

Answer 1

XAML

<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>

背后的代码

TextBlock textBlock = new TextBlock(new Run("A bit of text content..."));

textBlock.Background              = Brushes.AntiqueWhite;
textBlock.Foreground              = Brushes.Navy;

textBlock.FontFamily              = new FontFamily("Century Gothic");
textBlock.FontSize                = 12;
textBlock.FontStretch             = FontStretches.UltraExpanded;
textBlock.FontStyle               = FontStyles.Italic;
textBlock.FontWeight              = FontWeights.UltraBold;

textBlock.LineHeight              = Double.NaN;
textBlock.Padding                 = new Thickness(5, 10, 5, 10);
textBlock.TextAlignment           = TextAlignment.Center;
textBlock.TextWrapping            = TextWrapping.Wrap;

textBlock.Typography.NumeralStyle = FontNumeralStyle.OldStyle;
textBlock.Typography.SlashedZero  = true;

如果要加载自定义字体

controlID.FontFamily = new FontFamily("file:///Font
 Full Path");

Answer 2

拿一个控件，例如一个 TextBlock 并设置它的样式

Style style = new Style(typeof(TextBlock));

然后使用资源添加一个setter，如下所示

style.Setters.Add(new Setter(TextBlock.FontFamilyProperty, this.FindResource("NameOfResource")));

最后将样式设置为控件...

myTextBlock.Style = style;
