c# – 序列化类似的类

[Serializable]
    public class ExtendedAddressData
    {
        public String AddressLine1 { get; set; }
        public String AddressLine2 { get; set; }
        public String Country { get; set; }
        public String City { get; set; }
        public String Firstname { get; set; }
        public String Surname { get; set; }
        public String FakeField { get; set; }
    }

    [Serializable]
    public class AddressData
    {
        public String AddressLine1 { get; set; }
        public String AddressLine2 { get; set; }
        public String Country { get; set; }
        public String City { get; set; }
        public String ZipCode { get; set; }
        public String Firstname { get; set; }
        public String Surname { get; set; }
    }

我试图确保旧的AddressData在将来仍然可以反序列化,尽管序列化略有不同的类.

基本上应该清空空的(不存在的)字段,并且应该忘记那些被删除的字段.

我正在从Object到Byte [](以及后面)进行序列化.不是XML或JSON

private static byte[] ObjectToByteArray(object _Object)
    {
        try
        {
            var memoryStream = new MemoryStream();
            new BinaryFormatter().Serialize(memoryStream,_Object);
            return memoryStream.ToArray();
        }
        catch (Exception e)
        {
            Console.WriteLine("Exception caught in process: {0}",e);
        }
        return null;
    }

    private static object ByteArrayToObject(byte[] aBytes)
    {
        try
        {
            var memoryStream = new MemoryStream(aBytes);
            var serializedObject = new BinaryFormatter().Deserialize(memoryStream);
            return serializedObject;

        }
        catch (Exception e)
        {
            Console.WriteLine("Exception caught in process: {0}",e);
        }
        return null;
    }

这是一个简化的UnitTest,可能解释了我的尝试比我更好

public void LegacySerializationSupportTest()
    {
        var realData = new AddressData()
        {
            AddressLine1 = "AddressLine1",AddressLine2 = "AddressLine2",City = "City",Country = "Country",Firstname = "Firstname",Surname = "Surname",ZipCode = "ZipCode"
        };
        var bytearray = AddressRepository_Accessor.ObjectToByteArray(realData);

        AddressData realObject = (AddressData) AddressRepository_Accessor.ByteArrayToObject(bytearray);
        ExtendedAddressData fakeObject = (ExtendedAddressData) AddressRepository_Accessor.ByteArrayToObject(bytearray);
        Assert.AreEqual(realObject.AddressLine1,fakeObject.AddressLine1);
    }

有什么方法可以做到这一点,仍然使用bytearray而不是JSON或XML？
