title: Is there a way to serialize Dictionary<string, string> with an inner object?
body: <p>I have next dictionary</p>
  
  <pre><code> var invoiceParams = new Dictionary&lt;string, string&gt;();
   invoiceParams.Add("order_id", "111");
   invoiceParams.Add("goods", "[{amount:100, count: 2}]");
  
   var jsonString = JsonConvert.SerializeObject(invoiceParams);
  </code></pre>
  
  <p>Can I serialize it into next JSON with newtonsoft.json?</p>
  
  <pre><code>{
     "order_id":111,
     "goods":[
        {
           "amount":100,
           "count":2
        }
     ]
  }
  </code></pre>
