我正在使用一个RichEditBox，我有一些问题，保存和恢复RTF文本。
这是我导出的一个RTF文本示例，正如你所看到的，有不同的前景色和字体家族正确保存 （我手动缩进它以使其更容易阅读）：

{\rtf1\fbidis\ansi\ansicpg1252\deff0\nouicompat\deflang1040
    {\fonttbl{\f0\fnil\fcharset0 Segoe UI;}
    {\f1\fnil\fcharset0 Brush Script MT;}
    {\f2\fnil\fcharset0 Impact;}
    {\f3\fnil Segoe UI;}}
{\colortbl ;\red9\green105\blue192;\red0\green0\blue0;\red76\green152\blue25;\red208\green52\blue56;}
{\*\generator Riched20 10.0.14393}\viewkind4\uc1 
\pard\ltrpar\tx720\cf1\b\i\f0\fs23 Test\cf2\b0\i0\par
\pard\ltrpar\li320\qc\tx720\cf3\strike\f1\fs40 Some color\cf2\strike0\f0\fs23\par
\pard\ltrpar\tx720\cf4\f2 Hello!\cf2\f0\par
\f3\par
\f0\lang1033\par
\f3\par
\par
\pard\ltrpar\tx720\fs23\par
}

问题：我称

EditBox.Document.SetText(TextSetOptions.FormatRtf, myRtfString);

并且文本被加载到控件中，但是字体系列和前景色被完全忽略。我已经打过电话了

EditBox.Document.ApplyDisplayUpdates();

这并不能解决问题。我的意思是，为什么所有其他段落/字符选项都被正确恢复，但 * 只有字体系列和前景色被忽略 *？我是不是漏掉了什么？谢谢你，谢谢

编辑：这是我为RichEditBox使用的自定义Style：

此问题目前无法在最新的Windows 10 Build 14393中重现，代码如下：
XAML代码

... mc:Ignorable="d" Loaded="Page_Loaded">
<StackPanel Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
   <RichEditBox x:Name="EditBox"  Height="400" Margin="40"   >
   </RichEditBox> 
</StackPanel>

后面的代码：

private void Page_Loaded(object sender, RoutedEventArgs e)
{
    string myRtfString = @"{\rtf1\fbidis\ansi\ansicpg1252\deff0\nouicompat\deflang1040
 {\fonttbl{\f0\fnil\fcharset0 Segoe UI;}
 {\f1\fnil\fcharset0 Brush Script MT;}
 {\f2\fnil\fcharset0 Impact;}
 {\f3\fnil Segoe UI;}}
 {\colortbl ;\red9\green105\blue192;\red0\green0\blue0;\red76\green152\blue25;\red208\green52\blue56;}
 {\*\generator Riched20 10.0.14393}\viewkind4\uc1

 \f3\par
 \par
 \pard\ltrpar\tx720\fs23\par
 }";
    EditBox.Document.SetText(TextSetOptions.FormatRtf, myRtfString);
}

如果你仍然想在你的环境中找到一个解决方案，请尝试在“Focused ViewState”下找到以下代码，并将其注解掉。更多详情请参考this thread。

<ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Foreground" Storyboard.TargetName="ContentElement">
     <DiscreteObjectKeyFrame KeyTime="0" Value="{ThemeResource SystemControlForegroundChromeBlackHighBrush}"/>
 </ObjectAnimationUsingKeyFrames>
<ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="RequestedTheme" Storyboard.TargetName="ContentElement">
    <DiscreteObjectKeyFrame KeyTime="0" Value="Light"/>
</ObjectAnimationUsingKeyFrames>

我这边的结果是：

UWP RichEditBox在自己的OnLoaded事件中应用父Xaml控件的字体和颜色默认值。您可以通过查看同步RichEditBox：：TextChanging事件处理程序中的调用堆栈来查看它。在RichEditBox：：OnLoaded事件中再次重新应用RTF可修复此问题。
在上面的回答“这个问题目前无法在最新的windows 10 build 14393中通过如下代码再现.”RTF设置在Page_Loaded中，在RichEditBox：：OnLoaded之后，将Xaml默认值传播到RTF中。
