title: C# date formatting is losing slash separators
body: <p>If I do this in C#:</p>
  
  <pre><code>Console.WriteLine(DateTime.Now.ToString("ddd M/dd/yy"));
  </code></pre>
  
  <p>I would expect output like this:</p>
  
  <pre><code>Wed 6/15/11
  </code></pre>
  
  <p>But it actually outputs this:</p>
  
  <pre><code>Wed 6 15 11
  </code></pre>
  
  <p>Why are the slashes disappearing? Is there a way to prevent this and have the date outputted in the expected format?</p>
