title: Add rules and extract text from PDF using C# .net
body: <p>I want to build a PDF text extraction tool having similar features to this application (A-PDF Data Extractor) <a href="http://www.a-pdf.com/data-extractor/index.htm" rel="nofollow">http://www.a-pdf.com/data-extractor/index.htm</a> </p>
  
  <p>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.  </p>
  
  <p>How can I do this ? Is there a way to run another application inside my c# desktop application ? </p>
  
  <p>If you have a better options please let me know </p>
