json服务强制转换错误

Question

我有下面的代码纬度，纬度它显示0如何获取值请帮忙。

http://private-anon-397aeee05-karhoofleetintegration.apiary-mock.com/trip?version=2&karhoo_ref=karhoo_ref

       private void button1_Click(object sender, EventArgs e)
    {
        using (var client = new WebClient())
        {
            var json = client.DownloadString("http://private-anon-397aeee05-karhoofleetintegration.apiary-mock.com/trip?version=2&karhoo_ref=karhoo_ref.asmx");
            var serializer = new JavaScriptSerializer();
             BookingInformation bo = serializer.Deserialize<BookingInformation>(json.ToString());
        }
    }

public class BookingInformation
{
      public string karhoo_ref { get; set; }
public string booking_id { get; set; }

public string datetime_scheduled_utc { get; set; }
public string status { get; set; }
public bool is_asap { get; set; }
public decimal latitude { get; set; }
public decimal longitude { get; set; }

}

为了反序列化JSON，您需要提供反映JSON本身的对象，上面的内容甚至还没有完成。一个快速的JSON>C#类转换给出了以下结果：

public class Address
{
public string display_address { get; set; }
public string building_number { get; set; }
public string street_name { get; set; }
public string city { get; set; }
public string region { get; set; }
public string postal_code { get; set; }
public string country { get; set; }
}
public class Airport
{
public string airport_code { get; set; }
public string airline_code { get; set; }
public string terminal { get; set; }
public string flight_number { get; set; }
public int meet_greet { get; set; }
}
public class FromLocation
{
public double latitude { get; set; }
public double longitude { get; set; }
public Address address { get; set; }
public string comment { get; set; }
public Airport airport { get; set; }
}
public class Address2
{
public string display_address { get; set; }
public string building_number { get; set; }
public string street_name { get; set; }
public string city { get; set; }
public string region { get; set; }
public string postal_code { get; set; }
public string country { get; set; }
}
public class ToLocation
{
public double latitude { get; set; }
public double longitude { get; set; }
public Address2 address { get; set; }
public object comment { get; set; }
public object airport { get; set; }
}
public class Passenger
{
public string first_name { get; set; }
public string last_name { get; set; }
public string phone_number { get; set; }
public bool is_primary_contact { get; set; }
}
public class Direction
{
public int kph { get; set; }
public int heading { get; set; }
}
public class Vehicle
{
public string vehicle_type { get; set; }
public string vehicle_id { get; set; }
public string vehicle_plate { get; set; }
public double latitude { get; set; }
public double longitude { get; set; }
public object eta_minutes { get; set; }
public string make { get; set; }
public string model { get; set; }
public string color { get; set; }
public string status { get; set; }
public string driver_id { get; set; }
public string driver_phone { get; set; }
public string driver_first_name { get; set; }
public string driver_last_name { get; set; }
public Direction direction { get; set; }
}
public class RootObject
{
public string karhoo_ref { get; set; }
public string booking_id { get; set; }
public int datetime_scheduled_utc { get; set; }
public string status { get; set; }
public bool is_asap { get; set; }
public bool as_directed { get; set; }
public FromLocation from_location { get; set; }
public ToLocation to_location { get; set; }
public string notes { get; set; }
public int passenger_count { get; set; }
public int luggage_count { get; set; }
public List<Passenger> passengers { get; set; }
public Vehicle vehicle { get; set; }
}

因此，尝试将数据反序列化到这些类对象中。它至少应该给你数据。
