我正在尝试使用C#中的经度和纬度来获取2点之间的距离,现在我偶然发现了一些好的代码,并在我的代码中使用了它们,这是我得到的异常错误:
System.Net.WebException: 'Request Not Authorized or Over QueryLimit'
我的代码正在寻找:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using GoogleMaps.LocationServices;
using System.Device.Location;
namespace DistanceCalcConsole
{
class Program
{
static void Main(string[] args)
{
getDistancebetween2Points();
}
private static void getDistancebetween2Points()
{
var originAddress = "Lagos, Nigeria";
var locationService = new GoogleLocationService();
var point = locationService.GetLatLongFromAddress(originAddress);
var latitude1 = point.Latitude;
var longitude1 = point.Longitude;
var destinationAddress = "Ibadan, Nigeria";
var locationService2 = new GoogleLocationService();
var point2 = locationService2.GetLatLongFromAddress(destinationAddress);
var latitude2 = point.Latitude;
var longitude2 = point.Longitude;
var locA = new GeoCoordinate(latitude1, longitude1);
var locB = new GeoCoordinate(latitude2, longitude2);
double distance = locA.GetDistanceTo(locB);
double finalDistance = distance / 1000;
Console.Write(finalDistance +" Kilometers");
Console.Read();
}
}
}
看起来我缺少什么吗?是为了了解使用Googlemaps.Locationservice是免费的,所以我不应该期望这个错误...
答案 0 :(得分:1)
出现未授权或超出查询限制的错误的原因很少:
