title: Getting a specific field from a JSON string without deserializing in C#
body: <p>I currently have a REST app which returns a JSON string something like:</p>
  
  <p><code>[{error: "Account with that email exists"}]</code></p>
  
  <p>For when an error is thrown. I don't want to deserialize it into a custom "error" object, because it seems a bit wasteful and pointless. Is there a simple way to just extract a specific field out of a JSON string without making a custom class to reflect it.</p>
  
  <p>Thanks</p>
