Answer 1

span不是rtf标签，它是html，因此是“无法识别的结构”异常消息

尝试使用代码，或者将html源代码放入html＆gt;首先是RTF转换器。

修改

好吧，所以Span不是一个有效的rtf标签，但是它是一个有效的wpf类，可以很好地进入一个flowdocument，所以我想它可以在这种情况下工作。

您的代码存在一个问题：span类似乎没有任何“dir”属性：http://msdn.microsoft.com/en-us/library/system.windows.documents.span%28v=vs.110%29.aspx

所以我建议删除dir =“ltr”（如果我没记错的话，在这种情况下无论如何都是无用的）

使用rtf加载数据仅使用以下数据进行异常处理
