原文:

这是上篇 最后留给朋友思考的问题。

效果图：

XAML代码：

<Page xmlns="" xmlns:x="" >

<Canvas>

<TextBlock FontSize="84" FontFamily="Arial Black" Margin="0,0">

<TextBlock.TextDecorations>

<TextDecoration PenOffset="10" PenOffsetUnit="Pixel" PenThicknessUnit="Pixel">

 <TextDecoration.Pen>

          <Pen Thickness="5">

            <Pen.Brush>

              <LinearGradientBrush Opacity="0.5"

                StartPoint="0,0.5"  EndPoint="1,0.5">

                <LinearGradientBrush.GradientStops>

                  <GradientStop Color="Yellow" Offset="0" />

                  <GradientStop Color="Red" Offset="1" />

                </LinearGradientBrush.GradientStops>

              </LinearGradientBrush>

            </Pen.Brush>

          </Pen>

        </TextDecoration.Pen>

</TextDecoration>

<TextDecoration PenOffset="2" PenOffsetUnit="Pixel" PenThicknessUnit="Pixel">

 <TextDecoration.Pen>

          <Pen Thickness="1">

            <Pen.Brush>

              <SolidColorBrush Opacity="0.5" Color="Red"/>

            </Pen.Brush>

          </Pen>

        </TextDecoration.Pen>

</TextDecoration>

</TextBlock.TextDecorations>

GOOD

</TextBlock>

</Canvas>

</Page>

（其实就是使用多个TextDecoration而已！）
