title: Convert integer to hexadecimal and back again
body: <p>How can I convert the following?</p>
  
  <p>2934 (integer)  to   B76 (hex)</p>
  
  <p>Let me explain what I am trying to do. I have User IDs in my database that are stored as integers. Rather than having users reference their IDs I want to let them use the hex value. The main reason is because it's shorter.</p>
  
  <p>So not only do I need to go from integer to hex but I also need to go from hex to integer.</p>
  
  <p>Is there an easy way to do this in C#?</p>
