CivicAddressResolver.ResolveAddress(GeoCoordinate) Metode

Definisi

Secara sinkron menyelesaikan alamat syariah dari lokasi berdasarkan garis lintang dan bujur. Panggilan ini akan memblokir eksekusi utas panggilan saat alamat sedang diselesaikan.

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

Parameter

coordinate
GeoCoordinate

yang GeoCoordinate berisi lokasi untuk diselesaikan ke alamat syariah.

Mengembalikan

Alamat sekvic yang diselesaikan dari coordinate parameter . Unknown dikembalikan jika alamat tidak dapat diselesaikan.

Penerapan

Pengecualian

coordinateadalah null.

coordinate tidak berisi garis lintang dan bujur yang valid.

Contoh

Program berikut menunjukkan cara memanggil ResolveAddress untuk menyelesaikan alamat sinkron.

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

Keterangan

Peristiwa ResolveAddressCompleted dinaikkan ketika operasi penyelesaian alamat selesai. Alamat sekvic yang diselesaikan dari coordinate parameter dikembalikan oleh Address anggota ResolveAddressCompletedEventArgs objek yang diteruskan ke penanganan aktivitas.
