前面Json如何能反序列呀?

我写了一个MODEL
 class ObjectKG
    {
        [DataMember(Order = 0)]
        public string name { get; set; }
        [DataMember(Order = 1)]
        public string phase { get; set; }
        [DataMember(Order = 2)]
        public string open { get; set; }
        [DataMember(Order = 3)]
        public string[] detail { get; set; }
        [DataMember(Order = 4)]
        public string bonus { get; set; }
        [DataMember(Order = 5)]
        public string fn { get; set; }
        [DataMember(Order = 6)]
        public string trend { get; set; }
        [DataMember(Order = 7)]
        public string rule { get; set; }
        [DataMember(Order = 8)]
        public string color { get; set; }
        [DataMember(Order = 9)]
        public string url { get; set; }
        [DataMember(Order = 10)]
        public string news_url { get; set; }
        [DataMember(Order = 11)]
        public string buy_url { get; set; }
        [DataMember(Order = 12)]
        public string time_exchange { get; set; }
        [DataMember(Order = 13)]
        public string bet { get; set; }
        [DataMember(Order = 14)]
        public string prize { get; set; }
        [DataMember(Order = 15)]
        public string official_sort { get; set; }
        [DataMember(Order = 16)]
    }
但这个字串每个开始都是不同的数字,不知道该如何处理
------解决方案--------------------
不同的数字 有关系吗？？
