1. JsonConvert

JsonConvert.DeserializeObject()

  //参数data      "[{"VehicleId":"10247","GpsInstruction":1}]"   
      public List<InstructionData> RequestData(string data)
        {
            var instructionList = JsonConvert.DeserializeObject<List<InstructionData>>(data);
            return instructionList;
        }

  public class InstructionData
    {
        public string VehicleId { get; set; }
        public string DeviceId { get; set; }
        public string GpsInstruction { get; set; }
        public string GpsParamId { get; set; }
        public string GpsParamValue { get; set; }
        //1、终端参数设置 2、工作参数二 3、追踪设置 4、版本控制
        public string ParamType { get; set; }
    }

2. js 中  object   array   json 相互转化

                var codeValList = new Array();
                var obj = new Object();
                obj.VehicleId = $("#VehicleId").val();
                obj.GpsInstruction = type;
                //obj    Object { VehicleId="10247", GpsInstruction=1}
                codeValList = codeValList.concat(obj);
                //codeValList   [Object { VehicleId="10247", GpsInstruction=1}]
                var tempPar = JSON.stringify(codeValList);
                //tempPar  "[{"VehicleId":"10247","GpsInstruction":1}]"
