title: C# standard class (enumeration?) for Top, Bottom, Left, Right
body: <p>Is there a standard c# class that defines a notional Left, Right, Top and Bottom? </p>
  
  <p>Should I just use my own?</p>
  
  <pre><code>enum controlAlignment
  {
      left = 1,
      top,
      right,
      bottom,
      none = 0
  }
  </code></pre>
