title: Recursively getting files in a directory with several sub-directories
body: <p>I was wondering if anybody here could help me out as I'm still very new to C#.  I have a drive with folders w/in folders w/in folders that all contain files.  Is there a way to recursively loop through the files and gather up all of these file names into a .txt file?  </p>
  
  <p>I'm not sure how to implement this into my Console app--so does anybody have any code that might help?</p>
