Synchronously resolves a civic address from a location based on latitude and longitude. This call will block execution of the calling thread while the address is being resolved.

public:
 virtual System::Device::Location::CivicAddress ^ ResolveAddress(System::Device::Location::GeoCoordinate ^ coordinate);

public System.Device.Location.CivicAddress ResolveAddress (System.Device.Location.GeoCoordinate coordinate);

abstract member ResolveAddress : System.Device.Location.GeoCoordinate -> System.Device.Location.CivicAddress
override this.ResolveAddress : System.Device.Location.GeoCoordinate -> System.Device.Location.CivicAddress

Public Function ResolveAddress (coordinate As GeoCoordinate) As CivicAddress

Parameters

coordinate: GeoCoordinate

The GeoCoordinate containing the location to resolve to a civic address.

Returns

CivicAddress

The civic address that is resolved from the coordinate parameter. Unknown is returned if the address cannot be resolved.

Implements

ResolveAddress(GeoCoordinate)

Exceptions

ArgumentNullException

coordinate is null.

ArgumentException

coordinate does not contain a valid latitude and longitude.

Examples

The following program demonstrates how to call ResolveAddress to resolve a civic address synchronously.

using System;
using System.Device.Location;
namespace ResolveAddressSync
{
    class Program
    {
        static void Main(string[] args)
        {
            ResolveAddressSync();
        }
        static void ResolveAddressSync()
        {
            GeoCoordinateWatcher watcher = new GeoCoordinateWatcher(GeoPositionAccuracy.High);
            watcher.MovementThreshold = 1.0; // set to one meter
            watcher.TryStart(false, TimeSpan.FromMilliseconds(1000));

            CivicAddressResolver resolver = new CivicAddressResolver();

            if (watcher.Position.Location.IsUnknown == false)
            {
                CivicAddress address = resolver.ResolveAddress(watcher.Position.Location);

                if (!address.IsUnknown)
                {
                    Console.WriteLine("Country: {0}, Zip: {1}",
                            address.CountryRegion,
                            address.PostalCode);
                }
                else
                {
                    Console.WriteLine("Address unknown.");
                }
            }
        }
    }
}

Imports System.Device.Location

Module ResolveAddressSync

    Public Sub ResolveAddressSync()
        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))

        Dim resolver As CivicAddressResolver = New CivicAddressResolver()
        If started Then
            If Not watcher.Position.Location.IsUnknown Then
                Dim address As CivicAddress = resolver.ResolveAddress(watcher.Position.Location)
                If Not address.IsUnknown Then
                    Console.WriteLine("Country: {0}, Zip: {1}",
                                address.CountryRegion,
                                address.PostalCode)
                Else
                    Console.WriteLine("Address unknown.")
                End If
            End If
        Else
            Console.WriteLine("GeoCoordinateWatcher timed out on start.")
        End If
    End Sub


    Public Sub Main()

        ResolveAddressSync()
        Console.WriteLine("Enter any key to quit.")
        Console.ReadLine()
    End Sub

End Module

Remarks

The ResolveAddressCompleted event is raised when the address resolve operation completes. The civic address that is resolved from the coordinate parameter is returned by the Address member of the ResolveAddressCompletedEventArgs object that is passed to the event handler.
