CivicAddressResolver.ResolveAddress(GeoCoordinate) Metod

Definition

Namnområde:
System.Device.Location
Sammansättning:
System.Device.dll

Löser synkront en medborgerlig adress från en plats baserat på latitud och longitud. Det här anropet blockerar körningen av den anropande tråden medan adressen löses.

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

Parametrar

coordinate
GeoCoordinate

Den GeoCoordinate innehållande platsen som ska lösas till en medborgaradress.

Returer

CivicAddress

Den medborgerliga adress som löses från parametern coordinate . Unknown returneras om adressen inte kan matchas.

Implementeringar

ResolveAddress(GeoCoordinate)

Undantag

ArgumentNullException

coordinate är null.

ArgumentException

coordinate innehåller inte en giltig latitud och longitud.

Exempel

Följande program visar hur du anropar ResolveAddress för att lösa en medborgerlig adress synkront.

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

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

Kommentarer

Händelsen ResolveAddressCompleted utlöses när adressåtgärden slutförs. Den medborgerliga adress som löses från parametern coordinate returneras av Address medlemmen ResolveAddressCompletedEventArgs i objektet som skickas till händelsehanteraren.
