title: Displaying int[] values in a List
body: <p>I'm creating a list of X/Y coordinates.</p>
  <pre><code>List&lt;int[,]&gt; coordinateList = new List&lt;int[,]&gt;();
  </code></pre>
  <p>Then I'm adding to the list.</p>
  <pre><code>coordinateList.Add(new int[9, 15]);
  </code></pre>
  <p>And finally I'm trying to print the value of the first item in the list (the one I've just added).</p>
  <pre><code>System.Diagnostics.Debug.WriteLine(coordinateList[0].GetValue(0, 1));
  </code></pre>
  <p>I want this to be printing (9, 15). But it only ever prints 0.</p>
