title: How do we compare elements in two lists in a Where Clause (Linq)
body: <pre><code>class objA
  {
      public Rectangle area;    
  }
  
  class objB
  {
      public Point somepoint;
  }
  
  
  List&lt;objA&gt; listA;
  List&lt;objB&gt; listB;
  </code></pre>
  
  <p>Now, I want to get the elements in listA and listB wherever <code>objA.area.contains(objB.point)</code></p>
