.net 下word 中的图片与文字分离

最近在做一个项目要求word 中的图片与文字分离 ，找了好久终于找到一个完美的方法

 

c#实现word中的图文分离

 

part 1: class define

 part 2: usage code:

 

WordSeparator w =new WordSeparator();
w.SeparateImageText();

Shape 对象代表文档中的图形对象，

InlineShape 代表文档中的嵌入式图形对象，

但是我又遇到了另外一种问题，word 中的图片除了InlineShape  的图片外还有  Shape 

 如果将 Shape  转化为  InlineShape  就会报错

 对于shape 还是没法做到完全分离，希望大神指点一二
