关于地理坐标经纬度Josn解析位数问题解决方案

接口返回Josn数据{"Lat":30.18096950954861,"Lng":120.15840467664931,"speed":-1,"accuracy":13.7807184866474,"Type":2,"Province":"","City":"","Town":"","ProvinceName":"","CityName":"","TownName":"","Street":"","DetailAddress":"","worktype":1}

我们的一般解析方案：

 var dataobj = (JObject)JsonConvert.DeserializeObject(data);

然后我们获取到的lat和lng数据位数减少了，变成16位：

 Lat=30.1809695095486  Lng=120.
