uwp 和 c# 中的反向地理编码
Reverse Geocoding in uwp and c#
好的,我正在阅读有关反向地理编码的 Microsoft 文档
所以我正在尝试获取我的城市和国家/地区代码,我正在关注此
// The location to reverse geocode.
BasicGeoposition location = new BasicGeoposition();
location.Latitude = 47.643;
location.Longitude = -122.131;
Geopoint pointToReverseGeocode = new Geopoint(location);
// Reverse geocode the specified geographic location.
MapLocationFinderResult result =
await MapLocationFinder.FindLocationsAtAsync(pointToReverseGeocode);
// If the query returns results, display the name of the town
// contained in the address of the first result.
if (result.Status == MapLocationFinderStatus.Success)
{
tbOutputText.Text = "town = " +
result.Locations[0].Address.Town;
我正在尝试在我的应用程序中删除它,我知道地址具有我需要的那 2 个属性 (https://docs.microsoft.com/en-us/uwp/api/Windows.Services.Maps.MapAddress)
目前我的应用程序获取我的位置和坐标,但我怎样才能使反向地理编码工作。
public MainPage()
{
this.InitializeComponent();
var pos = GetCityData();
}
private async Task<string> GetCityData() {
var citydata = await LocationManager.GetGeopositionAsync();
BasicGeoposition geoposition = new BasicGeoposition() {
Latitude = citydata.Coordinate.Point.Position.Latitude, Longitude = citydata.Coordinate.Point.Position.Longitude
};
Geopoint geopoint = new Geopoint(geoposition);
MapLocationFinderResult finderResult = await MapLocationFinder.FindLocationsAtAsync(geopoint);
return $"{finderResult.Locations[0].Address.Town},{finderResult.Locations[0].Address.CountryCode}";
