问题 I'll try to describe my situation: I have Windows Store App (C#), which receive data from remote data base ( DataBase1 ), and store it in local database in isolated storage ( DataBase2 ).

问题 I have an enum, for example: [JsonConverter(typeof(MyJSONConverter))] public enum MyEnum { a, b, c } I have put the JsonConverter attribute on it. I have defined the converter class: public class MyJSONConverter : JsonConverter<MyEnum> { public MyJSONConverter() { } public override void WriteJson(JsonWriter writer, MyEnum value, JsonSerializer serializer) { serializer.Serialize(writer, value); } public override MyEnum ReadJson(JsonReader reader, Type objectType, MyEnum existingValue, bool
