问题 How can I convert Open XML to RTF in c#? I could use just an xslt to convert, just wandering if there is one already available or if there is a .net library that can do this. 回答1: Not sure if you are aware but there is an XSLT to convert Word Open Xml to Html called DocX2Html_IE.xslt https://openxmlviewer.svn.codeplex.com/svn/Source/OpenXMLViewer/DocX2Html_IE.xslt Which is part of the OpenXML Document Viewer on codeplex.
