VB: How to get all keys given Newtonsoft.Json.Linq.JObject
<p>I am using Newtonsoft.Json here (<a href="http://www.newtonsoft.com/json" rel="nofollow">http://www.newtonsoft.com/json</a>) in Visual basic program in visual studio 2015.</p>

<pre><code>Dim jObject As Newtonsoft.Json.Linq.JObject = Newtonsoft.Json.Linq.JObject.Parse(jsonString)
</code></pre>

<p>jsonString is:</p>

<pre><code>{
  "total": 2,
  "0":{
      "name": "component 0",
      "primary": "R"
  },
  "1":{
      "name": "component 1",
      "primary": "C"
  }
}
</code></pre>

<p>How to get all keys of sub dictionaries from jObject (in this case: "0" and "1")?</p>

<p>By the way, is there good API documents for newtonsoft in VB? There are so many in C#, but few in VB. difficult to use them in my program. Thanks.</p>
