asp.net 实现word在线阅读

最近接到一个案子需要实现把上传的word档案，在网页里面进行阅读，类似于百度文库。

1.最初的思路是用FlashPaper在线把word直接专程swf格式，结果放到iis就不能实现了，网上找了好多种解决方案都不能实现最终无赖只好放弃。

2.后来就用了折中的办法，把word文件上传的时候先转成pdf格式，然后再把pdf格式专程swf格式，最终用户看到的是swf格式。就实现了在线阅读的功能

现在把过程和代码给大家献上：

   1.先下载安装swftools工具：swftools下载

   2.然后下载FlexPaper：FlexPaper下载

   3.下载转word转pdf的aspose.word此dll可以不用下，我已经加到例子里面了，可以在例子里面找到
