以下為在.net mvc中，生成pdf的幾種方式，資料都是在做項目時網上找的
1、使用Microsoft.Office.Interop.Word.dll將word轉換為PDF
dll可以單獨下載，一般在電腦中有，位置：C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files\vs\199bd4f2\edef3bc1\assembly\dl3\60e90863\53bea978_07e9d401\Microsoft.Office.Interop.Word.DLL

3、wkhtmltopdf
What is it?
wkhtmltopdf and wkhtmltoimage are open source (LGPLv3) command line tools to render HTML into PDF and various image formats using the Qt WebKit rendering engine. These run entirely "headless" and do not require a display or display service.
There is also a C library, if you're into that kind of thing.
4、基於libcef 將html /url 保存為pdf
