[Mono-list] DataContractJsonSerializer Gives Different Results Depending OS

[fletcham]

I have written a small client - server application which passes JSON messages
back and forth.  The computer with the server application is running Windows
7 and the client application is on a Mac as well as on the iPhone using
MonoTouch.  When I serialize an object utilizing the
DataContractJsonSerializer it gives me two different JSON responses
depending on the OS I am using.  

On Windows 7 using mono/.net 3.5 it gives me this result:

[{"Suit":0},{"Suit":1},{"Suit":2}]

On OSX 10.6.5 using mono/.net 3.5 it gives me this result:

[{"__type":"Card:#JsonTest","Suit":0},{"__type":"Card:#JsonTest","Suit":1},{"__type":"Card:#JsonTest","Suit":2}]

Has anyone run into a similar problem or is this to be expected?

I have included a simple console application demonstrating the results
listed above.  For the console application to run you need to include two
reference: System.Runtime.Serialization and System.ServiceModel.Web.  If
anyone has any input on why this is and how to remedy it, it would be
greatly appreciated!

Thank you,
Adam


using System;
using System.Collections.Generic;
using System.Runtime.Serialization.Json;
using System.IO;
using System.Text;

namespace JsonTest
{
	class MainClass
	{
		public static void Main(string[] args)
		{
			Hand hand = new Hand();
			hand.Add(new Card { Suit = 0 });
			hand.Add(new Card { Suit = 1 });
			hand.Add(new Card { Suit = 2 });
			
			string json;
			
			DataContractJsonSerializer ser = new
DataContractJsonSerializer(hand.GetType());
			using (MemoryStream ms = new MemoryStream())
			{
				ser.WriteObject(ms, hand);
				json = Encoding.Default.GetString(ms.ToArray());
			} 
			
			Console.WriteLine(json); 
		}
	}

	public class Card
	{
		public int Suit { get; set; }
	}

	public class Hand : List
	{
		
	} 
}
