title: JSON.Net - Select without knowing the name
body: <p>I've got the following json:</p>
  
  <pre><code>    {
     "success":1,
     "return":{
        "29460691":{
           "amount":0.391199,
           "rate":0.00608
        },
        "29460690":{
           "amount":0.285893,
           "rate":0.00607,
        },
        "29460689":{
           "amount":0.322908,
           "rate":0.00606,
        }
  }
  </code></pre>
  
  <p>And want to find the first <em>rate</em> of a certain <em>amount</em>. So let's say I want to select the <em>rate</em> of the first order with the <em>amount</em> of "0.285893".</p>
  
  <p>How can I best make this with Newtonsoft? My biggest problem is selecting the number within JsonObject["return"].</p>
