title: How to get the list of all directories and subdirectories in a specified path using vb.net
body: <p>My directory structure is like below.</p>
  
  <p>Parent directory <br />
  ---Sub directory 1
  ---Sub directory 2 
  ------Sub directory2a
  ------Sub directory2b
  ---Sub directory 3 </p>
  
  <p>I am writing in VB.net to fetch all the directory names (including sub directories in all the levels)</p>
  
  <p>However while using directory.getfilesystementries(path) I am getting only the top level sub directories. Any idea on how to fetch all the subdirectory names of all sub levels?</p>
