Deserialize JSON to known and unknown types in a class

Question

I´m using C# MVC and have the following JSON:

MessageType: "Type1"

MessageData: {{Name: "Jonas"}, Phones: [{ Fixed: "12345", Mobile: "45678" }], Addresses: [{ Home: "ababa"} ... ], { HasId: "Yes }, ... }

The MessageData will contain different data depending on MessageType.

What I need is to deserialize it into the following C# structure:

public class AjaxMsg 
{
    public string MessageType { get; set; }
    public object MesssageData { get; set; }
}

I´m using the native serialization during the POST from client, but I only get the MessageType data.

Also, the code:

var msgDataString = MessageData.ToString()

returns "System.Object"

How can I get the MessageData accordingly as an object format ?

You can use JSON.NET's ToObject method:

JObject Data = Message.MessageData; 
Type type = Message.MessageType;
object obj = Data.ToObject(type); // if you dont know the type in compile time

MyType obj2 = Data.ToObject<MyType>(); // if you know the type in compile time

Create a wrapper class to deserialize :

[Serializable]
public class AjaxMsg
{
    [DataMember]
    public string MessageType { get; set; }

    [DataMember]
    public object MessageData { get; set; }
}

public class Data
{
    public IList< AjaxMsg> list {get;set;}
}

var obj = JsonConvert<Data>(json);
