title: C# Converting PDF file to Word doc and vice versa
body: <p>I need to highlight some random text to my PDF file. My friend advised me to convert the PDF to a Word document and parse the doc and do the highlighting before converting back to PDF. </p>
  
  <p>Is there any way to this highlighting of text? </p>
  
  <p>Any 3rd party library that can be use to convert PDF to doc and vice versa. Thanks. </p>
