私は2つのことだけをする必要があるアプリケーションを開発しています:

1)プッシュ通知を使用します。

2)起動時に特定の URLを開きます。

唯一のメインページ内にプッシュ通知コードを書きました。次のようになります。

namespace WindowsPush
{
    public partial class MainPage : PhoneApplicationPage
    {
        // Constructor
        public MainPage()
        {
            /// Holds the push channel that is created or found.
            HttpNotificationChannel pushChannel;

            // The name of our push channel.
            string channelName = "ToastSampleChannel";

            InitializeComponent();

            // Try to find the push channel.
            pushChannel = HttpNotificationChannel.Find(channelName);

            // If the channel was not found, then create a new connection to the push service.
            if (pushChannel == null)
            {
                pushChannel = new HttpNotificationChannel(channelName);

                // Register for all the events before attempting to open the channel.
                pushChannel.ChannelUriUpdated += new EventHandler<NotificationChannelUriEventArgs>(PushChannel_ChannelUriUpdated);
                pushChannel.ErrorOccurred += new EventHandler<NotificationChannelErrorEventArgs>(PushChannel_ErrorOccurred);

                // Register for this notification only if you need to receive the notifications while your application is running.
                //pushChannel.ShellToastNotificationReceived += new EventHandler<NotificationEventArgs>(PushChannel_ShellToastNotificationReceived);

                pushChannel.Open();

                // Bind this new channel for toast events.
                pushChannel.BindToShellToast();

            }
            else
            {
                // The channel was already open, so just register for all the events.
                pushChannel.ChannelUriUpdated += new EventHandler<NotificationChannelUriEventArgs>(PushChannel_ChannelUriUpdated);
                pushChannel.ErrorOccurred += new EventHandler<NotificationChannelErrorEventArgs>(PushChannel_ErrorOccurred);

                // Register for this notification only if you need to receive the notifications while your application is running.
                //pushChannel.ShellToastNotificationReceived += new EventHandler<NotificationEventArgs>(PushChannel_ShellToastNotificationReceived);

                // Display the URI for testing purposes. Normally, the URI would be passed back to your web service at this point.
                System.Diagnostics.Debug.WriteLine(pushChannel.ChannelUri.ToString());
                // MessageBox.Show(String.Format("Channel Uri is {0}", pushChannel.ChannelUri.ToString()));

            }


        }


        void PushChannel_ChannelUriUpdated(object sender, NotificationChannelUriEventArgs e)
        {
            Dispatcher.BeginInvoke(() =>
            {
                // Display the new URI for testing purposes.   Normally, the URI would be passed back to your web service at this point.
                System.Diagnostics.Debug.WriteLine(e.ChannelUri.ToString());
                MessageBox.Show(String.Format("Channel Uri is {0}", e.ChannelUri.ToString()));
            });
        }


        void PushChannel_ErrorOccurred(object sender, NotificationChannelErrorEventArgs e)
        {
            // Error handling logic for your particular application would be here.
            Dispatcher.BeginInvoke(() =>
                MessageBox.Show(String.Format("A push notification {0} error occurred.  {1} ({2}) {3}", e.ErrorType, e.Message, e.ErrorCode, e.ErrorAdditionalData)));
        }


    }
}

このコードは MainPage.xaml.cs 内にあります。ここで特定の URL を開くにはどうすればよいですか?

Windows Phone で URLを開くには、2 つの方法があります。

  • WebBrowserTaskを使用する
  • WebBrowser コントロールを使用する

    要件に応じて、上記のアプローチのいずれかを使用してURLのコンテンツを表示できます。
