如何设置<Linebreak />的高度

Question

有人知道如何设置<LineBreak />内部高度<TextBlock />吗？我试图改变字体大小,TextBlock但它没有帮助我.

UPDATE

我需要减少它,而不是增加.

唯一的方法我可以看到的一种可能性是使用FlowDocumentScrollViewer作为TextBlock的内容.它允许您使用具有Paragraph对象的FlowDocument,该对象具有FontSize和LineHeight属性.这将使您能够在一定程度上更改LineBreak的高度,这可能不会像您想要的那么小.

<Grid>
   <TextBlock LineHeight="1" Height="85" Width="400" HorizontalAlignment="Left" Margin="12,29,0,0" Name="textBlock1" VerticalAlignment="Top" Background="Beige" >
        <FlowDocumentScrollViewer Width="400" VerticalScrollBarVisibility="Hidden" >
            <FlowDocument>
                <Paragraph LineHeight="1" FontSize="12" FontFamily="Arial" Foreground="Red" >
                    <Run> This is a Test of line height</Run>
                 </Paragraph>
                <Paragraph LineHeight="1" FontSize="1"  BorderThickness=" 1" BorderBrush="Black">
                    <LineBreak/>
                </Paragraph >
                <Paragraph LineHeight="1" FontSize="12" FontFamily="Arial" Foreground="Blue">
                    <Run> This is a Test of line height</Run>
                </Paragraph> 
                <Paragraph LineHeight="1" FontSize="2"  BorderThickness=" 1" BorderBrush="Black">
                    <LineBreak />
                </Paragraph>
                <Paragraph   LineHeight="1" FontSize="12" FontFamily="Arial" Foreground="Green" >  
                    <Run> This is a Test of line height</Run>
                </Paragraph>
                <Paragraph LineHeight="1" FontSize="5"  BorderThickness=" 1" BorderBrush="Black">
                    <LineBreak />
                </Paragraph>
            </FlowDocument>
        </FlowDocumentScrollViewer>
    </TextBlock>
</Grid>

这给了我这样的结果.

添加一些其他信息.我相信你在线之间看到的大部分差距都与文本行的LineHeight有关.我玩了一点点,然后想出了这个.它还具有不需要流文档的额外好处.

<TextBlock LineHeight="9.75" LineStackingStrategy="BlockLineHeight" Margin="12,188,-12,-188">
    <Run> This is a Test of Line Height</Run>
    <LineBreak />
    <Run >This is a Test of Line Height</Run>
    <LineBreak />
    <Run>This is a Test of Line Height</Run>
    <LineBreak />
    <Run> This is a Test of Line Height</Run>
</TextBlock>

这给了我一个看起来像这样的结果.它会让你比你原来要小
