Could not find token at index 0

[frankinstien]

The Json below is valid and was serialized by FastJson but I get a "Could not find token at index 0" error when I try to de-serialize it. Any ideas as to what can cause this? { "$types": { "CategoryModels.WordEntry, CategoryModels, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null": "1" }, "$type": "1", "Class": ["K2JFO+FwG0CfeuTFE283AQ=="], "EdgePaths": [-1537686140], "RelatedWords": [], "Word": "Tum-ti-tum", "Plural": false, "TenseState": "present", "RootForm": "AAAAAAAAAAAAAAAAAAAAAA==", "ID": "78LPEHC0wkiQQu6DvX9wzQ==", "UseFrequency": 0, "PartsofSpeech": [] }

` [DataContract] [Serializable] public class WordEntry { [DataMember] public List Class { set; get; } [DataMember] public List EdgePaths { set; get; } [DataMember] public List RelatedWords { set; get; } [DataMember] public String Word { set; get; } [DataMember] public bool Plural { set; get; } [DataMember] public Tense TenseState { set; get; } [DataMember] public Guid RootForm { set; get; } [DataMember] public Guid ID { set; get; } [DataMember] public Single UseFrequency { set; get; } [DataMember] public List PartsofSpeech { set; get; }

   public WordEntry()
  {
  }

} `

Is Class a List<Guid>?

[frankinstien]

Yes, it is.

The following works fine:

    public class WordEntry
    {
        public List<Guid> Class { set; get; }
        public List<int> EdgePaths { set; get; }
        public List<int> RelatedWords { set; get; }
        public String Word { set; get; }
        public bool Plural { set; get; }
        //public Tense TenseState { set; get; }
        public Guid RootForm { set; get; }
        public Guid ID { set; get; }
        public Single UseFrequency { set; get; }
        public List<int> PartsofSpeech { set; get; }
    }

    [Test]
    public static void emptylist()
    {
        var s = "{ 'Class': ['K2JFO+FwG0CfeuTFE283AQ=='], 'EdgePaths': [-1537686140], 'RelatedWords': [], 'Word': 'Tum-ti-tum', 'Plural': false, 'TenseState': 'present', 'RootForm': 'AAAAAAAAAAAAAAAAAAAAAA==', 'ID': '78LPEHC0wkiQQu6DvX9wzQ==', 'UseFrequency': 0, 'PartsofSpeech': [] }";

        var o = JSON.ToObject<WordEntry>(s.Replace("\'","\""));

    }
