title: Deserialize only one property of a JSON file
body: <p>I am faced with a problem. 
  I want to deserialize a complex JSON response from a server, but I only need one part of it.</p>
  
  <p>Here is an example:</p>
  
  <pre><code>{
   "menu": {
    "id": "file",
    "value": "File",
    "popup": {
      "menuitem": [
        {"value": "New", "onclick": "CreateNewDoc()"},
        {"value": "Open", "onclick": "OpenDoc()"},
        {"value": "Close", "onclick": "CloseDoc()"}
      ]
    }
   }
  }
  </code></pre>
  
  <p>I also used Csharp2json to get the class objects that I need, I just modified the menu class according to my needs :</p>
  
  <pre><code>    public class Menuitem
  {
      public string value { get; set; }
      public string onclick { get; set; }
  }
  
  public class Popup
  {
      public IList&lt;Menuitem&gt; menuitem { get; set; }
  }
  
  public class Menu
  {
      public Popup popup { get; set; }
  }
  
  public class RootObjectJourney
  {
      public Menu menu { get; set; }
  }
  </code></pre>
  
  <p>Now, how do I deserialize if I only need the popup value and his children?</p>
