windows-phone-7 - Windows Phone API 有地理编码器吗？

Question

如何在 Windows Phone 中将地理坐标转换为地址？ 在 Android 中，可以通过 android.location.Geocoder 实现。

获取包含地理编码 API 的 System.Device.dll。

//Instantiate 
GeoCoordinateWatcher watcher = null;
watcher = new GeoCoordinateWatcher(GeoPositionAccuracy.Default);
watcher.PositionChanged += 
    new EventHandler<GeoPositionChangedEventArgs<GeoCoordinate>>(OnPositionChanged);
watcher.Start();

//Use
void OnPositionChanged(object sender, GeoPositionChangedEventArgs<GeoCoordinate> e)    
{
    //stop & clean up, we don’t need it anymore
    watcher.Stop();
    watcher.Dispose();
    watcher = null;   
    location = e.Position.Location;
}

和地理编码:

var reverseGeocodeRequest = new ReverseGeocodeRequest();

// Set the credentials using a valid Bing Maps key
reverseGeocodeRequest.Credentials = new BingMaps.Credentials();    
reverseGeocodeRequest.Credentials.ApplicationId = "ENTER YOUR BING MAPS KEY HERE";

// Set the point to use to find a matching address    
BingMaps.Location point = new BingMaps.Location();
point.Latitude = location.Latitude;
point.Longitude = location.Longitude;

reverseGeocodeRequest.Location = point;

// Make the reverse geocode request
GeocodeServiceClient geocodeService = new  
    GeocodeServiceClient("BasicHttpBinding_IGeocodeService");

geocodeService.ReverseGeocodeCompleted += new
    EventHandler<ReverseGeocodeCompletedEventArgs>
        (geocodeService_ReverseGeocodeCompleted);

geocodeService.ReverseGeocodeAsync(reverseGeocodeRequest);
