Примеры

В следующем примере показано, ResolveAddressCompletedEventArgsкак использовать.The following example shows how to use the ResolveAddressCompletedEventArgs.

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

Конструкторы

ResolveAddressCompletedEventArgs(CivicAddress, Exception, Boolean, Object)

Инициализирует новый экземпляр ResolveAddressCompletedEventArgs.Initializes a new instance of ResolveAddressCompletedEventArgs.

Свойства

Address

Получает объект CivicAddress, связанный с событием ResolveAddressCompleted.Gets the CivicAddress associated with the ResolveAddressCompleted event.

Cancelled

Возвращает значение, показывающее, была ли отменена асинхронная операция.Gets a value indicating whether an asynchronous operation has been canceled.

(Унаследовано от AsyncCompletedEventArgs)
Error

Возвращает значение, показывающее, какая ошибка произошла в течение асинхронной операции.Gets a value indicating which error occurred during an asynchronous operation.

(Унаследовано от AsyncCompletedEventArgs)
UserState

Возвращает уникальный идентификатор для асинхронной задачи.Gets the unique identifier for the asynchronous task.

(Унаследовано от AsyncCompletedEventArgs)

Методы

Equals(Object)

Определяет, равен ли заданный объект текущему объекту.Determines whether the specified object is equal to the current object.

(Унаследовано от Object)
GetHashCode()

Служит хэш-функцией по умолчанию.Serves as the default hash function.

(Унаследовано от Object)
GetType()

Возвращает объект Type для текущего экземпляра.Gets the Type of the current instance.

(Унаследовано от Object)
MemberwiseClone()

Создает неполную копию текущего объекта Object.Creates a shallow copy of the current Object.

(Унаследовано от Object)
RaiseExceptionIfNecessary()

Вызывает предоставленное пользователем исключение в случае неудачного выполнения асинхронной операции.Raises a user-supplied exception if an asynchronous operation failed.

(Унаследовано от AsyncCompletedEventArgs)
ToString()

Возвращает строку, представляющую текущий объект.Returns a string that represents the current object.
