如何将序列化的匿名对象转换回object？

using System;
using System.IO;
using System.Runtime.Serialization;
using System.Xml;

public class Program
{
    public static void Main()
    {
        // 序列化匿名对象
        var anonymousObject = new { Name = "John", Age = 30 };
        var serializer = new DataContractSerializer(anonymousObject.GetType());
        var stream = new MemoryStream();
        serializer.WriteObject(stream, anonymousObject);
        stream.Position = 0;

        // 反序列化为object
        var deserializer = new DataContractSerializer(typeof(object));
        var deserializedObject = deserializer.ReadObject(stream);

        Console.WriteLine(deserializedObject);
    }
}

using System;
using System.IO;
using System.Runtime.Serialization.Json;

public class Program
{
    public static void Main()
    {
        // 序列化匿名对象
        var anonymousObject = new { Name = "John", Age = 30 };
        var serializer = new DataContractJsonSerializer(anonymousObject.GetType());
        var stream = new MemoryStream();
        serializer.WriteObject(stream, anonymousObject);
        stream.Position = 0;

        // 反序列化为object
        var deserializer = new DataContractJsonSerializer(typeof(object));
        var deserializedObject = deserializer.ReadObject(stream);

        Console.WriteLine(deserializedObject);
    }
}
