title: How to replace text in a PDF with C#?
body: <p>I saw a lot of solutions in here but none are clear or good answers.</p>
  
  <p>Here is my simple question, hoping with a straight answer.</p>
  
  <p>I have a PDF file (a template) which is created having text something like this:</p>
  
  <blockquote>
    <blockquote>
      <p>{FIRSTNAME} {LASTNAME} {ADDRESS} {PHONENUMBER}</p>
    </blockquote>
  </blockquote>
  
  <p>is it possible to have C# code that replace these templates with a text of my choice?</p>
  
  <p>No fields, no other complex stuff.</p>
  
  <p>Is there any Open source library helping me achieve that?</p>
