在主函数中

string serverUrl_g = "http://qs.cnpms.cn:6050/getparkingfee/?from=&plate=%E4%BA%ACA99999";            //上传的数据                 string Data = DingDanHao.Text;                string response_g = Service.HttpGetConnectToServer(serverUrl_g, Data);                            SiWoData result = new SiWoData();                Dictionary<string, object> dic=result.SiWodatas(serverUrl_g, Data);                Label.Content = "车牌号：" + DingDanHao.Text + "\r\n" + "支付方式：微信支付" + "\r\n " +"驶入时间："+ result.dic["InTime"] + "\r\n " +"驶出时间"+ result.dic["OutTime"];

result.dic["InTime"]

如此调用即可显示，即先将json数据转换为字典，返回字典，再实例化对象调用。
