title: How to get element by key in JSON array
body: <p>I have the following JArray object (newtonsoft.json)</p>
  
  <pre><code>[
    {
      "Administrator": 3
    },
    {
      "User": 1
    },
    {
      "Guest": 5
    }
  ]
  </code></pre>
  
  <p>How do I retrieve the value (3) for key "Administrator" ? It's asking me for an array index but I would like to retrieve by key.. as this list can expand and contract..</p>
