title: 2D boolean array, check if array contains a false
body: <p>I'm using a 2D array of booleans in C#. I've looked up the Array.Exists function at <a href="http://www.dotnetperls.com/array-exists" rel="nofollow">dot net pearls</a> but I can't get it to work, either because I'm using booleans or because it's a 2D array.</p>
  
  <pre><code>bool[,] array = new bool[4, 4];
  
  if (array.Contains(false)) {}; // This line is pseudo coded to show what I'm looking for
  </code></pre>
