Occurs when the address resolution that was initiated by a call to ResolveAddressAsync(GeoCoordinate) completes.
public:
virtual event EventHandler<System::Device::Location::ResolveAddressCompletedEventArgs ^> ^ ResolveAddressCompleted;
public event EventHandler<System.Device.Location.ResolveAddressCompletedEventArgs> ResolveAddressCompleted;

The following program shows how to call ResolveAddressAsync to resolve a civic address asynchronously.

using System.Device.Location;
namespace ResolveAddressSync

public static void Main(string[] args)
{

}

{
GeoCoordinateWatcher watcher = new GeoCoordinateWatcher(GeoPositionAccuracy.High);
bool started = false;
watcher.MovementThreshold = 1.0; // set to one meter
started = watcher.TryStart(false, TimeSpan.FromMilliseconds(1000));
if (started)
{
CivicAddressResolver resolver = new CivicAddressResolver();
resolver.ResolveAddressCompleted += new EventHandler<ResolveAddressCompletedEventArgs>(resolver_ResolveAddressCompleted);
if (watcher.Position.Location.IsUnknown == false)
{
resolver.ResolveAddressAsync(watcher.Position.Location);
}
}
}
static void resolver_ResolveAddressCompleted(object sender, ResolveAddressCompletedEventArgs e)
{
if (!e.Address.IsUnknown)
{
Console.WriteLine("Country: {0}, Zip: {1}",
e.Address.CountryRegion,
e.Address.PostalCode);
}
else
{
Console.WriteLine("Unknown address.");
}
}
}
}
