Initiates a request to resolve a latitude/longitude location to an address.
public:
void ResolveAddressAsync(System::Device::Location::GeoCoordinate ^ coordinate);
public void ResolveAddressAsync (System.Device.Location.GeoCoordinate coordinate);
abstract member ResolveAddressAsync : System.Device.Location.GeoCoordinate -> unit
Public Sub ResolveAddressAsync (coordinate As GeoCoordinate)
Parameters
- coordinate
- GeoCoordinate
The latitude/longitude location to resolve to an address.
Examples
The following example shows how to call ResolveAddressAsync.
static void ResolveAddressAsync()
{
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.");
}
}
Public Sub ResolveCivicAddressAsync()
Dim watcher As GeoCoordinateWatcher
watcher = New System.Device.Location.GeoCoordinateWatcher(GeoPositionAccuracy.High)
Dim started As Boolean = False
watcher.MovementThreshold = 1.0 'set to one meter
started = watcher.TryStart(False, TimeSpan.FromMilliseconds(1000))
If started Then
Dim resolver As CivicAddressResolver = New CivicAddressResolver()
AddHandler resolver.ResolveAddressCompleted, AddressOf resolver_ResolveAddressCompleted
If Not watcher.Position.Location.IsUnknown Then
resolver.ResolveAddressAsync(watcher.Position.Location)
End If
End If
watcher.Start()
End Sub
Sub resolver_ResolveAddressCompleted(ByVal sender As Object, ByVal e As ResolveAddressCompletedEventArgs)
If Not e.Address.IsUnknown Then
Console.WriteLine("Country: {0}, Zip: {1}",
e.Address.CountryRegion,
e.Address.PostalCode)
Else
Console.WriteLine("Unknown address.")
End If
End Sub
Remarks
This method stores in the task it returns all non-usage exceptions that the method's synchronous counterpart can throw. If an exception is stored into the returned task, that exception will be thrown when the task is awaited. Usage exceptions, such as ArgumentException, are still thrown synchronously. For the stored exceptions, see the exceptions thrown by ResolveAddress(GeoCoordinate).
