title: Replace method in C# not working for individual character?
body: <p>I've been looking around and it seems like I'm using this properly, but the results are failing.  I want to go through and get rid of any 0's and replace them with o's.</p>
  
  <pre><code>newString = strOld.Replace('0', 'o'); // doesn't work.
  
  newString = strOld.Replace("0", "o"); // doesn't work either.  
  </code></pre>
  
  <p>Am I doing something wrong?</p>
