Json.NET: Serialization Callbacks in base object

问题

Using Json.NET are Serialization Callbacks supported when the OnDeserializedAttribute is placed on a base class method? For example using this object graph:

[DataContract]
public class StubData:StubBase {}

[DataContract]
public class StubBase {
    public string Id { get; set; }

    [OnDeserialized]
    public void OnDeserialized(StreamingContext context) {
        Id = "1";
    }
}

var stubData = JsonConvert.DeserializeObject<StubData>(@"{""anyData"":""Foo""}");

stubData.Id //returns 1

Yes. OnDeserialized is supported. See the documentation

Here's a working cs-script example. Needs Newtonsoft.Json.dll is the same directory

//css_ref Newtonsoft.Json.dll

using System;
using System.Windows.Forms;
using Newtonsoft.Json;
using System.Runtime.Serialization;

public class StubData:StubBase {}

public class StubBase {
    public string Id { get; set; }

    [OnDeserialized]
    public void OnDeserialized(StreamingContext context) {
        Id = "1";
    }
}

class Script
{
    [STAThread]
    static public void Main(string[] args)
    {
      var stubData = JsonConvert.DeserializeObject<StubData>(@"{""anyData"":""Foo""}");
      Console.WriteLine(stubData.Id); //returns 1
    }
}

This prints
