title: Convert List<Property> To JObject
body: <p>Consider this code:</p>
  
  <pre><code>var joWork = ((JObject) x).Properties()
      .Where(p =&gt; p.Value.Type == JTokenType.String).ToList();
  </code></pre>
  
  <p>I end up with a <code>List&lt;JProperty&gt;</code>. </p>
  
  <p>Is there a quick way using Linq or a JSON.NET function to convert that <code>List&lt;JProperty&gt;</code> object to a JObject without building a JObject from scratch in a loop?</p>
