newtonsoft JSON序列化程序无法使用c＃属性初始化程序反序列化集合

Question

假设你有一个简单的对象如下：

    public class PaymentLineItem
{
    public DateTime TimeStamp { get; set; }

    public decimal Amount { get; set; }

    public string Description { get; set; }

    public PayCodeDto PayCode { get; set; } //= PayCodeDto.Invalid;

    public override string ToString()
    {
        return StringUtils.ToString(this);
    }

    public override bool Equals(object obj)
    {
        return Equals(obj as PaymentLineItem);
    }

    public override int GetHashCode()
    {
        unchecked
        {
            var hashCode = TimeStamp.GetHashCode();
            hashCode = (hashCode * 397) ^ Amount.GetHashCode();
            hashCode = (hashCode * 397) ^ (Description != null ? Description.GetHashCode() : 0);
            hashCode = (hashCode * 397) ^ (PayCode != null ? PayCode.GetHashCode() : 0);
            return hashCode;
        }
    }

    public bool Equals(PaymentLineItem other)
    {
        if (other == null) return false;
        if (ReferenceEquals(this, other)) return true;

        return TimeStamp.Equals(other.TimeStamp)
               && Amount.Equals(other.Amount)
               && string.Equals(Description, other.Description)
               && Object.Equals(PayCode, other.PayCode);
    }
}

除了使用C＃6.0中引入的新C＃auto-property initialize之外，这个类没有什么特别之处。 PayCodeDto 很简单，有三个属性并实现了IEquatable。

如果您创建这些付款项目的集合并使用

序列化

   var serialized = JsonConvert.SerializeObject(sut);

然后使用正确的序列化字符串并使用

反序列化

  var deserialized = JsonConvert.DeserializeObject<List<PaymentLineItemLight>>(serialized);

您最终得到的是具有相同PayCode的所有订单项实例的集合。

这是样本测试：

 [Test]
        public void Should_Serialize_Collection_In_Package_Correctly()
        {
            var sut = new List<PaymentLineItemLight>
            {
                new PaymentLineItemLight
                {
                    Amount = new decimal(153.0000),
                    Description = "48385 - Multiple items payment",
                    TimeStamp = DateTime.Parse("2018-01-30T10:40:47.477"),
                    PayCode = new PayCodeDto("105", "dont-care") {DictionaryId = 2}
                },
                new PaymentLineItemLight
                {
                    Amount = new decimal(53.0000),
                    Description = "483816 - Multiple items payment",
                    TimeStamp = DateTime.Parse("2018-01-30T10:40:47.477"),
                    PayCode = new PayCodeDto("104", "dont-care") {DictionaryId = 2}
                },
                new PaymentLineItemLight
                {
                    Amount = new decimal(200.0000),
                    Description = "483817 - Multiple items payment",
                    TimeStamp = DateTime.Parse("2018-01-30T10:40:47.477"),
                    PayCode = new PayCodeDto("102", "dont-care-102") {DictionaryId = 2}
                }
            };

            var serialized = JsonConvert.SerializeObject(sut);
            var deserialized = JsonConvert.DeserializeObject<List<PaymentLineItemLight>>(serialized);

            CollectionAssert.AreEqual(sut, deserialized);
        }

如果我删除了自动属性初始化，则测试通过。我必须在这里遗漏一些东西。有谁见过这个？
