title: flag enum confusion C#
body: <p>According to my code a=1, b=2, c=3 etc. I thought the flag would make a=1, b=2, c=4, etc</p>
  
  <pre><code>[Flags]
  public enum someEnum { none, a, b, c, d, e, f, }
  </code></pre>
  
  <p>How do i get what i intended(c=4, e=8)? and what does the <code>[Flags]</code> mean above?</p>
