title: Random number in a loop
body: <p>having an issue generating random numbers in a loop. Can get around it by using Thread.Sleep but after a more elegant solution.</p>
  
  <pre><code>for ...
      Random r = new Random();
      string += r.Next(4);
  </code></pre>
  
  <p>Will end up with 11111... 222... etc.</p>
  
  <p>Suggestions?</p>
