关于richtextbox的XAML属性

[a121984376]

ritchtextbox的XAML属性赋值的时候出现一些问题.
字符串:

<Section xml:space="preserve" HasTrailingParagraphBreakOnPaste="False" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"><Paragraph FontSize="11" FontFamily="Portable User Interface" Foreground="#FF000000" FontWeight="Normal" FontStyle="Normal" FontStretch="Normal" TextAlignment="Left">
  <Run Text="aaa" />
</Paragraph><Paragraph FontSize="11" FontFamily="Portable User Interface" Foreground="#FF000000" FontWeight="Normal" FontStyle="Normal" FontStretch="Normal" TextAlignment="Left">
  <Run Text="aaaa" />
</Paragraph></Section>

赋值后就成了这样:

<Section xml:space="preserve" HasTrailingParagraphBreakOnPaste="False" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"><Paragraph FontSize="11" FontFamily="Portable User Interface" Foreground="#FF000000" FontWeight="Normal" FontStyle="Normal" FontStretch="Normal" TextAlignment="Left">
<Run Text="aaa" />
<Run Text="" />
</Paragraph>
<Paragraph FontSize="11" FontFamily="Portable User Interface" Foreground="#FF000000" FontWeight="Normal" FontStyle="Normal" FontStretch="Normal" TextAlignment="Left">
<Run Text="aaaa" />
<Run Text="" />
</Paragraph></Section>

每一行多了一个<Run Text="" />,这是怎么回事???

可能和richtextbox中的空格有关吧。。。

是不是你赋值的过程有问题？

好好看看richbox的api

也可以用这种方式绑定

  
           Paragraph nw1 = new Paragraph();
            Run r3 = new Run();
            r3.Text += "要显示的内容 " ;
            nw1.Inlines.Add(r3);
            rtbChat.Selection.Insert(nw1);
