推荐答案

我觉得你不能用作为其文本没有格式选项一个TextBox做到这一点。不知道，如果标签允许，但文本块可能会帮助您：

I think you can't do it with a TextBox as its text has no formatting options. Not sure if the Label allows it, but the TextBlock might help you:

<TextBlock>
  <TextBlock.Triggers>
    <EventTrigger RoutedEvent="Loaded">
      <BeginStoryboard>
        <Storyboard>
          <ColorAnimation Storyboard.TargetName="scb01"
                          Storyboard.TargetProperty="Color"
                          From="White"
                          To="Black"
                          Duration="0:0:0.5"
                          AutoReverse="True"
                          RepeatBehavior="Forever" />
        </Storyboard>
      </BeginStoryboard>
    </EventTrigger>
  </TextBlock.Triggers>
  One <Run>
    <Run.Foreground>
      <SolidColorBrush x:Name="scb01"
                        Color="Red" />
    </Run.Foreground>
    Two</Run> Three
</TextBlock>
