如何将json对象反序列化为复杂对象？

Question

I'm trying to deserialize a JSON object into an Object with some "object" attribute that may be different each time. I have a serializer/deserializer function that works fine when using simple variable types or defined ones.

I tried to cast the object into the correct class, tried to get the object as dynamic, etc. However, I always get an exception: "Object Reference not established..."

Deserialization func:

        public static T deserializeJSON<T>(string json)
        {
            T obj = Activator.CreateInstance<T>();
            using (MemoryStream ms = new MemoryStream(Encoding.Unicode.GetBytes(json)))
            {
                DataContractJsonSerializer serializer = new DataContractJsonSerializer(obj.GetType($
                obj = (T)serializer.ReadObject(ms);
            }
            return obj;
        }

Example object:

 [DataContract]
    class Client
    {
        [DataMember] private string name;
        [DataMember] private string address;
        [DataMember] private string bio;
        [DataMember] private object specific; //WHERE SPECIFIC MAY BE ANY OTHER OBJECT THAT I CAST AFTER DESERIALIZATION
    }

Example object2:

 [DataContract]
    class Server
    {
        [DataMember] private string name;
        [DataMember] private int value;
    }

The specific attribute may be any other object. Imagine "specific" attribute is a Server type object; The deserialization function loads all attributes well instead of specific that is loaded as an object, but cannot convert it to Server.

PD: At deserialization moment, I know what class type is the "specific" attribute.

Thanks!

using latest json.net you can use

dynamic data = Json.Decode(json);

or

dynamic data = JObject.Parse(json);

and can access data with following code :

data.Date; 
data.Items.Count; 
data.Items[0].Name; 
data.Items[0].Price; 
data.Items[1].Name;
