When using DataContractJsonSerializer to serialize a dictionary, like so:

[CollectionDataContract]
public class Clazz : Dictionary<String,String> {}

    ....

    var c1 = new Clazz();
    c1["Red"] = "Rosso";
    c1["Blue"] = "Blu";
    c1["Green"] = "Verde";

Serializing c1 with this code:

    var dcjs = new DataContractJsonSerializer(c1.GetType());
    var json = new Func<String>(() =>
        {
            using (var ms = new System.IO.MemoryStream())
            {
                    dcjs.WriteObject(ms, c1);
                    return Encoding.ASCII.GetString(ms.ToArray());
            }
        })();

...produces this JSON:

[{"Key":"Red","Value":"Rosso"},
 {"Key":"Blue","Value":"Blu"},
 {"Key":"Green","Value":"Verde"}]

But, this isn't a Javascript associative array. If I do the corresponding thing in javascript: produce a dictionary and then serialize it, like so:

var a = {};
a["Red"] = "Rosso";
a["Blue"] = "Blu";
a["Green"] = "Verde";

// use utility class from http://www.JSON.org/json2.js
var json = JSON.stringify(a);

The result is:

{"Red":"Rosso","Blue":"Blu","Green":"Verde"}

How can I get DCJS to produce or consume a serialized string for a dictionary, that is compatible with JSON2.js ?

I know about JavaScriptSerializer from ASP.NET. Not sure if it's very WCF friendly. Does it respect DataMember, DataContract attributes?
