title: string to JsonObject in C#
body: <p>What is the best way to convert a (properly Json-formatted) <code>String</code> object into a <code>System.Json.JsonObject</code>?  Right now I create a <code>StringReader</code> and use <code>System.Json.JsonObject.Load</code>.</p>
  
  <p>(This is really kind of academic, since I think I'll always be dealing with the raw Json in <code>System.IO.Stream</code> form.)</p>
