Can not get value after parse in the version 2.3.3 upper

[hikaripro]

Dear support,

With example dungvu-qe in issuess : https://github.com/mgholam/fastJSON/issues/132

I have a issue when try to update your lib from 2.3.1 to the latest version. My code is run in .net core 3.1/5.0

Here my test, if I use the 2.3.1 the function is OK, but upgrade it to newer versions, it always fail. Could you check it for me?

Example :

static class Program { private static bool _isTestJson = true; ///

/// The main entry point for the application. ///

static void Main() { var directory = Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location); string pathToExe = directory + "\fastJSON.dll"; //var fileInfo = new FileInfo(pathToExe); var versionInfo = FileVersionInfo.GetVersionInfo(pathToExe); string version = versionInfo.FileVersion; Console.WriteLine("Start test FastJson: " + version); TestEnumJson.RunTestCase(); Console.ReadLine(); } }

namespace QuantEdge.Worker.TestFastJsonNetCore.Runner { public class TestEnumJson { public static void RunTestCase() { Console.WriteLine("Start run test case"); var obj = new ExtendMessage() { Layer1 = LayerEnum.L1, Layer2 = LayerEnum.L2, Layer3 = LayerEnum.L3, Layer4 = LayerEnum.L4, }; var lstObj = new List(); lstObj.Add(obj); lstObj.Add(obj);

        Console.WriteLine("----------------TEST CASE 1--------------------------");
        var stringJson = JSON.ToJSON(obj);
        Console.WriteLine("stringJson: " + stringJson);
        ParseTo_BaseMessage(stringJson);
        ParseTo_AbstractMessage(stringJson);

        Console.WriteLine("----------------TEST CASE 2--------------------------");
        var stringJsonList = JSON.ToJSON(lstObj);
        Console.WriteLine("stringJsonList: " + stringJsonList);
        ParseTo_ListBaseMessage(stringJsonList);
        ParseTo_ListAbstractMessage(stringJsonList);
        ParseTo_DefaultList(stringJsonList);

        Console.ReadLine();
    }

    private static void ParseTo_BaseMessage(string stringJson)
    {
        Console.WriteLine("-------TEST : ");
        Console.WriteLine("Deserialize msg to : BaseMessage");
        var objParse = JSON.ToObject<BaseMessage>(stringJson);
        CheckMsg(objParse);
    }

    private static void ParseTo_AbstractMessage(string stringJson)
    {
        Console.WriteLine("-------TEST : ");

public enum LayerEnum

public class ExtendMessage : Message

public class Message : BaseMessage

}

public class BaseMessage : AbstractMessage

public abstract class AbstractMessage

public interface IMessage

}

Result use fastjson ver 2.3.1 :
