JsonConvert.DeserializeObject 對象屬性為空

解決方法:

給T類加上帶參的構造函數，為成員變量賦值

一開始我的T類如下：

 public class OrderQueryParam : QueryParam
    {
        public string TypeCode { get; set; }
        public string Type { get; set; }
        public string Status { get; set; }
        public string StartTime { get; set; }
        public string EndTime { get; set; }
        public string TraderId { get; set; }
        public string Token { get; set; }
    }

JsonConvert.DeserializeObject<OrderQueryParam>反序列化后結果部分屬性為Null,

后面加了個帶參構造函數（如下），就得到正確結果了

public class OrderQueryParam : QueryParam
    {
        public string TypeCode { get; set; }
        public string Type { get; set; }
        public string Status { get; set; }
        public string StartTime { get; set; }
        public string EndTime { get; set; }
        public string TraderId { get; set; }
        public string Token { get; set; }

        public OrderQueryParam(string typeCode,string type,string status,string startTime,string endTime,string traderId,string token)
        {
            this.TypeCode = typeCode;
            this.Type = type;
            this.Status = status;
            this.StartTime = startTime;
            this.EndTime = endTime;
            this.TraderId = traderId;
            this.Token = token;
            
        }
    }
