Add rules and extract text from PDF using C# .net

I want to build a PDF text extraction tool having similar features to this application (A-PDF Data Extractor) http://www.a-pdf.com/data-extractor/index.htm

I am planning to do this in c# .net so I want to build my own interface similar to this app buy referencing this application(dll or exe). But it wont let me to add reference.

How can I do this ? Is there a way to run another application inside my c# des开发者_如何学Cktop application ?

If you have a better options please let me know

  Thank You

Any help is appreciate!!

If you want to use the exe file you must use the Process Class in the .net Framework. You have some example here: http://dotnetperls.com/process-start

If you need a library to extract the text from the pdf try to use iTextSharp: http://www.codeproject.com/KB/cs/PDFToText.aspx

Hope this helps
