Test case (already in SVN). Mono return String.Empty instead of null.

        [Test]
        [Category ("NotWorking")]
        public void ReadWriteNullObject ()
        {
            DataContractJsonSerializer dcjs = new DataContractJsonSerializer
(typeof (string));
            using (MemoryStream ms = new MemoryStream ()) {
                dcjs.WriteObject (ms, null);
                ms.Position = 0;
                using (StreamReader sr = new StreamReader (ms)) {
                    string data = sr.ReadToEnd ();
                    Assert.AreEqual ("null", data, "WriteObject(stream,null)");

                    ms.Position = 0;
                    Assert.IsNull (dcjs.ReadObject (ms), "ReadObject(stream)");
                }
            };
        }
