title: Convert from Object to QueryString
body: <p>How can I covert this object string</p>
  
  <pre><code>products=[{"PRICE":39.95,"RECIPIENT":{"ZIPCODE":"11779"},"CODE":"F1-509"}] 
  </code></pre>
  
  <p>to QueryString in C# as a parameter in an URL?</p>
  
  <p>I still have a problem because products - a JSON encoded string containing an array of product structures .Products is the parameter of the URL which the RECIPIENT object is inside RootObject.</p>
  
  <pre><code>var order = new RootObject()
  
          {
              Price = 39.95,
              Code = "F1-509",
              Recipient = new RECIPIENT
              {
                  Zipcode = "11779"
              }
          };
  </code></pre>
  
  <p>I need to convert Products Parameter to query which pass by URL in C# with GetAsync(URL).</p>
