範例

以下範例說明如何利用該 BaselineAlignment 屬性在包含的方框內對齊文字（此例 Paragraph為 ）。

<Page xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
  <FlowDocumentReader>
    <FlowDocument ColumnWidth="800">
      <Paragraph Background="Blue">

        <!-- The large text forces a large containing box size for the paragraph.
             The smaller text fragments align themselves vertically within this  
             box according to their BaselineAlignment values. -->
        <Span FontSize="40">Baseline:</Span>
        <Span BaselineAlignment="Baseline">Baseline</Span>
        <Span BaselineAlignment="Top">Top</Span>
        <Span BaselineAlignment="Bottom">Bottom</Span>
        <Span BaselineAlignment="Center">Center</Span>
      </Paragraph>
      <Paragraph Background="Green">

        <!-- The BaselineAlignment values of Subscript and Superscript below
             force the containing box to be larger then it normally would be. -->
        <Span FontSize="40">Baseline:</Span>
        <Span BaselineAlignment="Subscript">Subscript</Span>
        <Span BaselineAlignment="Baseline">Baseline</Span>
        <Span BaselineAlignment="Superscript">Superscript</Span>
      </Paragraph>
      <Paragraph Background="Yellow" LineHeight="60" LineStackingStrategy="BlockLineHeight">

        <!-- A deliberate BlockLineHeight stacking strategy change, to show the difference between Top/TextTop 
        and Bottom/TextBottom-->
        <Span FontSize="40" BaselineAlignment="Baseline">Baseline:</Span>
        <Span BaselineAlignment="Top">Top</Span>
        <Span BaselineAlignment="TextTop">TextTop</Span>
        <Span BaselineAlignment="Bottom">Bottom</Span>
        <Span BaselineAlignment="TextBottom">TextBottom</Span>
      </Paragraph>
    </FlowDocument>
  </FlowDocumentReader>
</Page>
