1.下载并应用LitJson,DLL文件

2.建两个类；

public class JsonData    {        public string result { get; set; }        public List info { get; set; }    }
      public GameData()        { }        #region Model        private int _id;        private string _dept;        private string _sid;        private string _oldsid;        private string _userid;        private string _roleid;        private string _rolename;        private string _rolelevel;        private string _gold;        private string _money;        private string _inittime;        private string _lastlogin;        private string _querytime;        /// 
        ///         /// 
        public int ID        {            set { _id = value; }            get { return _id; }        }        ///

        public string dept        {            set { _dept = value; }            get { return _dept; }        }        /// 
        /// 服务器编号        /// 
        public string sid        {            set { _sid = value; }            get { return _sid; }        }        /// 
        /// 原始服务器编号        /// 
        public string oldsid        {            set { _oldsid = value; }            get { return _oldsid; }        }        /// 
        /// 用户平台ID        /// 
        public string userid        {            set { _userid = value; }            get { return _userid; }        }        ///

        public string roleid        {            set { _roleid = value; }            get { return _roleid; }        }        /// 
        /// 角色名        /// 
        public string rolename        {            set { _rolename = value; }            get { return _rolename; }        }        /// 
        /// 角色等级        /// 
        public string rolelevel        {            set { _rolelevel = value; }            get { return _rolelevel; }        }        ///

        public string inittime        {            set { _inittime = value; }            get { return _inittime; }        }        /// 
        /// 最后登录时间        /// 
        public string lastlogin        {            set { _lastlogin = value; }            get { return _lastlogin; }        }        /// 
        /// 查询时间        /// 
        public string querytime        {            set { _querytime = value; }            get { return _querytime; }        }        #endregion Model

3.读取数据

string json_str = @"{""result"":""1"",""info"":[{""sid"":""2"",""rolename"":""蒲翠柏"",""roleid"":""900001"",""lastlogin"":""2014-01-08 10:54:52"",""inittime"":""2013-11-15 12:01:05.0"",""money"":""867"",""rolelevel"":""55"",""userid"":""athena"",""oldsid"":""1"",""gold"":""9992837"",""dept"":""67"",""querytime"":""2014-01-08 11:56:38""},{""sid"":""2"",""rolename"":""噗"",""roleid"":""5700001"",""lastlogin"":""2013-11-16 18:38:54"",""inittime"":""2013-11-16 18:25:45.0"",""money"":""0"",""rolelevel"":""27"",""userid"":""athena"",""oldsid"":""1"",""gold"":""0"",""dept"":""67"",""querytime"":""2014-01-08 11:56:38""},{""sid"":""2"",""rolename"":""惠光赫"",""roleid"":""2800001"",""lastlogin"":""2013-11-15 15:00:07"",""inittime"":""2013-11-15 14:59:25.0"",""money"":""0"",""rolelevel"":""1"",""userid"":""athena"",""oldsid"":""1"",""gold"":""0"",""dept"":""67"",""querytime"":""2014-01-08 11:56:38""}]}";
               GameWindowsService.Common.JsonData jsonData = LitJson.JsonMapper.ToObject(json_str);
                List gameDataList = jsonData.info;                foreach (var gameData in gameDataList)                {                    Common.Common.WriteFile(gameData.Add().ToString());                }
