title: Reading/Writing PDF Files in Visual C# Windows Forms
body: <p>For a client, I need to be able to read and write PDF files. There are two downsides to this:</p>
  
  <ol>
  <li>I don't know how.</li>
  <li>I can't use any third-party copmonents/libraries.</li>
  </ol>
  
  <p>Can somebody please point me into the right direction where I might be able to learn how to begin reading and writing PDF files?</p>
  
  <p>I'm not asking for code or anything like that (although..... ;)), I'm just wondering if anybody knows of any good starting points...</p>
