title: Cannot create an instance of the abstract class or interface 'System.Array'
body: <p>I'm watching a VS 2010 tutorial video and he goes like this:</p>
  
  <pre><code>public static ArrayList GetRoomByType(string roomType)
  </code></pre>
  
  <p>When I try to do it in my VS 2013, the ArrayList doesn't seem to work, I tried making it: </p>
  
  <pre><code>public static Array GetRoomByType(string roomType)
  </code></pre>
  
  <p>and it goes fine, but when he do:</p>
  
  <pre><code>ArrayList list = new ArrayList();
  </code></pre>
  
  <p>of course I'll go:</p>
  
  <pre><code>Array list = new Array();
  </code></pre>
  
  <p>But then again the error </p>
