问题
I want to read PDF files from my .net application. Are there any free libraries available to do this?
回答1:
If you are looking for free PDF Read/Write .Net library, then you can visit
https://itextpdf.com/ (previously itextsharp)
Note: As mentioned by Dexters, this is library no more free for commercial purpose. It comes under Affero General Public License (AGPL)

You could take a look at PDFSharp: http://www.pdfsharp.com/PDFsharp/

PDFBox is open source and supports advanced text extraction. It also supports lucene search so it's ideal for creating a lucene index.
