推荐答案

PDF和DOCX文件不是文本文件，使用字符串函数进行拆分。 :-)



要使用PDF，请参阅这组可以使用的PDF库： http://csharp-source.net/open-source/pdf-libraries 。



To使用.docx，请参阅：

http://www.microsoft.com/en-us/download/details.aspx?id=30425 [ ^ ]，

http://openxmldeveloper.org [ ^ ]。



开放S.来自Microsoft Open Technologies的资源： https://github.com/OfficeDev/Open-XML-SDK [ ^ ]。



现在，关于阅读Word文档： https://msdn.microsoft.com/ en-us / library / office / ff478541.aspx [ ^ ]。



此CodeProject文章也很有用：使用OpenXML和C＃编辑Word文档，无需自动化/互操作 [ ^ ]。

PDF and DOCX files are not text files, to be split using string functions. :-)

To work with PDF, please see this set of referenced to PDF libraries you can use: http://csharp-source.net/open-source/pdf-libraries.

To work with .docx, please see:
