PDF Reader in .NET

Question

I want to read PDF files from my .net application. Are there any free libraries available to do this?

Answer 1

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

Answer 2

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)

Answer 3

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