title: Find a value from a hashtable
body: <p>If I were having a Generic list I would have done some thing like this</p>
  
  <pre><code>myListOfObject.FindAll(x=&gt;(x.IsRequired==false));
  </code></pre>
  
  <p>What if I need to do similar stuff in <code>Hashtable</code>? Copying to temporary <code>hashtable</code> and looping and comparing would be that last thing I would try :-(</p>
