我们知道,文字的修饰包括:空心字、立体字、划线字、阴影字、加粗、倾斜等。这里只说划线字的修饰方式,按划线的位置,我们可将之分为:上划线、中划线、基线与下划线。如图:
从上至下,分别为上划线(Overline),中划线(StrikeThrough),基线(Baseline)和下划线(Underline)。
如何实现?
(1)XAML代码:
<Page xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" >
<TextBlock TextDecorations="Strikethrough" FontSize="72" FontFamily="Arial">A</TextBlock>
</Page>
这里TextDecorations属性可以设置为:OverLine, Strikethrough, Baseline, Underline或None,如果没有设置TextDecorations属性,则默认为None,即不带划线修饰。
(2)使用C#代码:
private void SetDefaultStrikethrough()
{
textBlock1.TextDecorations = TextDecorations.Strikethrough;
}
(为了简洁,这里只列出相关的关键代码,其他代码未用C#列出。textBlock1为TextBlock的名称,在XAML中使用 x:Name="textBlock1"形式标记)
如果要更复杂点的效果,比如需要设置划线的颜色、线粗等,如下图:
如何制作类似效果呢?方法是:设置TextBlock的TextDecorations属性,再对TextDecoration的Pen属性进行设置。
如下XAML代码:
<Page xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" >
<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="0.8" 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.DashStyle>
<DashStyle Dashes="1,2,3"/>
</Pen.DashStyle>
</Pen>
</TextDecoration.Pen>
</TextDecoration>
</TextBlock.TextDecorations>
GOOD
</TextBlock>
</Canvas>
</Page>
C#关键代码:
private void SetLinearGradientUnderline()
{
TextDecoration myUnderline = new TextDecoration(); Pen myPen = new Pen();
myPen.Brush = new LinearGradientBrush(Colors.Yellow, Colors.Red, new Point(0, 0.5), new Point(1, 0.5));
myPen.Brush.Opacity = 0.8;
myPen.Thickness = 5;
myPen.DashStyle = DashStyles.Dash;
myUnderline.Pen = myPen;
myUnderline.PenThicknessUnit = TextDecorationUnit.FontRecommended; TextDecorationCollection myCollection = new TextDecorationCollection();
myCollection.Add(myUnderline);
textBlockGood.TextDecorations = myCollection;
}
引申问题:可不可以同时画上划线、中划线和下划线?比如:可不可以画如下图所示的文武线呢?
答案是:可以!留给有兴趣的朋友去思考吧。
