C# 如何从Windows Phone 8.1获取当前国家/地区位置以及可能的国家/地区代码

如何从Windows Phone 8.1获取当前国家/地区位置以及可能的国家/地区代码？我这样做了，但是FindLocationAsync抛出了一个异常“值不在预期范围内”

这就是所谓的反向地理定位

 var geolocator = new Geolocator();
            geolocator.DesiredAccuracyInMeters = 100;
            Geoposition position = await geolocator.GetGeopositionAsync();

             //reverse geocoding
            BasicGeoposition myLocation = new BasicGeoposition
            {
                Longitude = position.Coordinate.Longitude,
                Latitude = position.Coordinate.Latitude
            };
            Geopoint pointToReverseGeocode = new Geopoint(myLocation);

            MapLocationFinderResult result = await MapLocationFinder.FindLocationsAtAsync(pointToReverseGeocode);

             //here also it should be checked if there result isn't null and what to do in such a case
            string country = result.Locations[0].Address.Region;

你应该试试这个。。我宣布Map_事件 私有异步无效

private async void mapNearByUser\u mapptapped（Windows.UI.Xaml.Controls.Maps.MapControl发送方，Windows.UI.Xaml.Controls.Maps.MapInputEventArgs args args）
{
//你的地图被点击了
Geopoint pointToReverseGeocode=新的地质点（参数位置位置）；
//对指定的地理位置进行反向地理编码。
MapLocationFinderResult结果=
等待MapLocationFinder.FindLocationStatasync（指针反向代码）；
var resultText=新的StringBuilder（）；
尝试
{
if（result.Status==MapLocationFinderStatus.Success）
{
resultText.AppendLine（result.Locations[0].Address.District+“，“+result.Locations[0].Address.Town+”，“+result.Locations[0].Address.Country）；
}
MessageBox（resultText.ToString（））；
}
抓住
{
//MessageBox（resultText.ToString（））；
MessageBox（“请稍候…”）；
}
}

 var geolocator = new Geolocator();
            geolocator.DesiredAccuracyInMeters = 100;
            Geoposition position = await geolocator.GetGeopositionAsync();

             //reverse geocoding
            BasicGeoposition myLocation = new BasicGeoposition
            {
                Longitude = position.Coordinate.Longitude,
                Latitude = position.Coordinate.Latitude
            };
            Geopoint pointToReverseGeocode = new Geopoint(myLocation);

            MapLocationFinderResult result = await MapLocationFinder.FindLocationsAtAsync(pointToReverseGeocode);

             //here also it should be checked if there result isn't null and what to do in such a case
            string country = result.Locations[0].Address.Region;
