Deserializing a class with a Queue<T> with Newtonsoft.Json - json

Question

I have a class that has a property of type Queue. When trying to deserialize the JSON, I get the following error:
Type specified in JSON 'ConsoleApplication1.Task[], ConsoleApplication1, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' is not compatible with 'System.Collections.Generic.Queue`1[[ConsoleApplication1.Task, ConsoleApplication1, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]], System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'. Path 'Tasks.$type', line 1, position 140.
I have included the sample application below and I am using Newtonsoft.Json 4.5.10.15407.
The reason I am using a Queue instead of List or Dictionary is because I must preserve insert order. I've also tried searching in the docs and other questions but haven't really found anything concrete. Any help is much appreciated. Thank you.
namespace ConsoleApplication1
{
using System;
using System.Collections.Generic;
using System.Text;
using Newtonsoft.Json;
class Program
{
static void Main(string[] args)
{
Message message = new Message
{
MessageID = 1,
Tasks = new Queue<Task>()
};
message.Tasks.Enqueue(new Task{TaskId = 1, Message = "Test1", Parameters = "Param1"});
message.Tasks.Enqueue(new Task{TaskId = 2, Message = "Test2", Parameters = "Param2"});
byte[] bSerialized = SerializeJsonWithPrefix(message);
Message deserializedMessage = DeserializeJson(bSerialized, typeof (Message));
}
public static byte[] SerializeJsonWithPrefix(Message item)
{
JsonSerializerSettings jss = new JsonSerializerSettings();
jss.TypeNameHandling = TypeNameHandling.All;
return Encoding.UTF8.GetBytes(JsonConvert.SerializeObject(item, jss));
}
public static Message DeserializeJson(byte[] ueaData, Type concreteType)
{
JsonSerializerSettings jss = new JsonSerializerSettings();
jss.TypeNameHandling = TypeNameHandling.All;
// --- Error occurs here ---
var result = JsonConvert.DeserializeObject(Encoding.UTF8.GetString(ueaData), concreteType, jss);
return (Message)result;
}
}
public class Message
{
public int MessageID { get; set; }
public Queue<Task> Tasks { get; set; }
}
public class Task
{
public int TaskId { get; set; }
public string Message { get; set; }
public string Parameters { get; set; }
}
}

Version 5 solves your problem.

I stick to List<T> and Dictionary<string, T> when using JSON.NET serialization, where T is some JSON-serializable type. These correspond nicely to the JSON array and object types (see json.org).
If you serialize a List<T> and then deserialize it, JSON.NET will of course maintain the ordering. I would advise just translating between your Queue<T> and a List<T> for serialization, rather than trying to add behavior for directly serializing the Queue<T>.
