title: Deserialize none standard Json with System.Text.Json
body: <p>I have to deserialize into a object the following json string:</p>
  <pre><code>var jsonString = @&quot;[[{&quot;&quot;OU2CJ3-UBRYG-KCPVS6&quot;&quot;:{&quot;&quot;cost&quot;&quot;:&quot;&quot;27187.08000&quot;&quot;,&quot;&quot;vol_exec&quot;&quot;:&quot;&quot;3.40000000&quot;&quot;,&quot;&quot;fee&quot;&quot;:&quot;&quot;27.18708&quot;&quot;,&quot;&quot;avg_price&quot;&quot;:&quot;&quot;7996.20000&quot;&quot;}}]]&quot;;
  </code></pre>
  <p>Into a model, for instance like the following one :</p>
  <pre><code>public class OrderInfo
  {
      public string OrderId { get; set; }
      public Info Info { get; set; }
  }
  
  public class Info
  {
      public decimal avg_price { get; set; }
  
      public decimal cost { get; set; }
  
      public decimal fee { get; set; }
  
      public decimal vol_exec { get; set; }
  }
  </code></pre>
  <p>I have tried without success with this kind of code:</p>
  <pre><code>var nodes = JsonNode.Parse(jsonString);
  foreach (var order in nodes[0].AsArray())
  {
    // ??
  }
  </code></pre>
  <p>Or :</p>
  <pre><code>var info = JsonSerializer.Deserialize&lt;OrderInfo&gt;(jsonString);
  </code></pre>
  <p>How can I handle a Json without clear {&quot;Property&quot;: &quot;name&quot;} structure by using System.Text.Json framework ?</p>
