You could create your own class of type Quiz and then deserialize with strong type:

Example:

quizresult = JsonConvert.DeserializeObject<Quiz>(args.Message,
                 new JsonSerializerSettings
                 {
                     Error = delegate(object sender1, ErrorEventArgs args1)
                     {
                         errors.Add(args1.ErrorContext.Error.Message);
                         args1.ErrorContext.Handled = true;
                     }
                 });

And you could also apply a schema validation.

This is a simple example of JSON parsing by taking example of google map API  This will return City name of given zip code   using System  using System Collections Generic  using System Linq  using System Web  using System Web UI  using System Web UI WebControls  using Newtonsoft Json  using System Net   namespace WebApplication1       public partial class WebForm1   System Web UI Page               WebClient client   new WebClient            string jsonstring          protected void Page Load object sender  EventArgs e                                protected void Button1 Click object sender  EventArgs e                        jsonstring   client DownloadString  http   maps googleapis com maps api geocode json address   txtzip Text Trim                 dynamic dynObj   JsonConvert DeserializeObject jsonstring                Response Write dynObj results 0  address components 1  long name

You can use this tool to create appropriate c  classes   http   jsonclassgenerator codeplex com   and when you will have classes created you can simply convert string to object       public static T ParseJsonObject lt T gt  string json  where T   class  new                 JObject jobject   JObject Parse json           return JsonConvert DeserializeObject lt T gt  jobject ToString             Here that classes  http   ge tt 2KGtbPT v 0 c  Just fix namespaces
