c# - 反序列化 JSON 项目

Question

我有一个返回 JSON 的函数，如下所示:

jsonParsed = {
  "account-number": "xxxxxxxx",
  "symbol": "XLE   230120C00070000",
  "instrument-type": "Equity Option",
  "underlying-symbol": "XLE",
  "quantity": 3,
  "quantity-direction": "Short",
  "close-price": "7.64",
  "average-open-price": "7.95",
  "average-yearly-market-close-price": "7.95",
  "average-daily-market-close-price": "7.64",
  "multiplier": 100,
  "cost-effect": "Debit",
  "is-suppressed": false,
  "is-frozen": false,
  "restricted-quantity": 0,
  "expires-at": "2023-01-20T15:15:00-06:00",
  "realized-day-gain": "0.0",
  "realized-day-gain-effect": "None",
  "realized-day-gain-date": "2022-07-05",
  "realized-today": "0.0",
  "realized-today-effect": "None",
  "realized-today-date": "2022-07-05",
  "created-at": "xxxx-xx-xxxxx:xx:xx.xxx-xx:00",
  "updated-at": "xxxx-xx-xxxxx:xx:xx.xx-xx:00"
}

我正在尝试将其反序列化为 C# 类:

public class PositionResult
{
    public string AccountNumber { get; set; }
    public string Symbol { get; set; }
    public string InstrumentType { get; set; }
    public string UnderlyingSymbol { get; set; }
    public string Quantity { get; set; }
    public string QuantityDirection { get; set; }
    public string ClosePrice { get; set; }
    public string AverageOpenPrice { get; set; }
    public string AverageYearlyMarketClosePrice { get; set; }
    public string AverageDailyMarketClosePrice { get; set; }
    public string multiplier { get; set; }
    public string CostEffect { get; set; }
    public string IsSuppressed { get; set; }
    public string IsFrozen { get; set; }
    public string RestrictedQuantity { get; set; }
    public string ExpiresAt { get; set; }
    public string RealizedDayGain { get; set; }
    public string RealizedDayGainEffect { get; set; }
    public string RealizedDayGainDate { get; set; }
    public string RealizedToday { get; set; }
    public string RealizedTodayEffect { get; set; }
    public string RealizedTodayDate { get; set; }
    public string CreatedAt { get; set;}
    public string UpdatedAt { get; set;}

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

dataDeSerialized = JsonConvert.DeserializeObject<PositionResult>(jsonParsed, new 
JsonSerializerSettings()
{
     NullValueHandling = NullValueHandling.Ignore
});

但是，dataDeSerialized 中的大多数字段都为空，但有一些异常(exception)。我怀疑 "xxxx": "xxxx" 格式有问题，但我不确定我做错了什么？

C# 类属性名称应与 json 属性名称相同。同步它们的常用方法是使用 Newtonsoft.Json 的 [JsonProperty] 属性。试试这个类(class)

    public class PositionResult
   {
        [JsonProperty("account-number")]
        public string AccountNumber { get; set; }

        [JsonProperty("symbol")]
        public string Symbol { get; set; }

        [JsonProperty("instrument-type")]
        public string InstrumentType { get; set; }

        [JsonProperty("underlying-symbol")]
        public string UnderlyingSymbol { get; set; }

        [JsonProperty("quantity")]
        public long Quantity { get; set; }

        [JsonProperty("quantity-direction")]
        public string QuantityDirection { get; set; }

        [JsonProperty("close-price")]
        public string ClosePrice { get; set; }

        [JsonProperty("average-open-price")]
        public string AverageOpenPrice { get; set; }

        [JsonProperty("average-yearly-market-close-price")]
        public string AverageYearlyMarketClosePrice { get; set; }

        [JsonProperty("average-daily-market-close-price")]
        public string AverageDailyMarketClosePrice { get; set; }

        [JsonProperty("multiplier")]
        public long Multiplier { get; set; }

        [JsonProperty("cost-effect")]
        public string CostEffect { get; set; }

        [JsonProperty("is-suppressed")]
        public bool IsSuppressed { get; set; }

        [JsonProperty("is-frozen")]
        public bool IsFrozen { get; set; }

        [JsonProperty("restricted-quantity")]
        public long RestrictedQuantity { get; set; }

        [JsonProperty("expires-at")]
        public DateTimeOffset ExpiresAt { get; set; }

        [JsonProperty("realized-day-gain")]
        public string RealizedDayGain { get; set; }

        [JsonProperty("realized-day-gain-effect")]
        public string RealizedDayGainEffect { get; set; }

        [JsonProperty("realized-day-gain-date")]
        public DateTimeOffset RealizedDayGainDate { get; set; }

        [JsonProperty("realized-today")]
        public string RealizedToday { get; set; }

        [JsonProperty("realized-today-effect")]
        public string RealizedTodayEffect { get; set; }

        [JsonProperty("realized-today-date")]
        public DateTimeOffset RealizedTodayDate { get; set; }

        [JsonProperty("created-at")]
        public string CreatedAt { get; set; }

        [JsonProperty("updated-at")]
        public string UpdatedAt { get; set; }

   
    }
