Windows phone 8 Windows Phone 8频道更新未触发

我在开发Windows Phone推送通知时遇到问题。根本没有触发

ChannelUriUpdated

事件。当我注册

ConnectionStatusChanged

事件时，如下所示：

  void pushChannel_ConnectionStatusChanged(object sender, NotificationChannelConnectionEventArgs e)
    {
        var state = e.ConnectionStatus;
    }

并且，

连接状态更改

会持续触发。“状态”值交替连接和断开

我使用代码：

任何帮助都将不胜感激。

使用下面的代码为我工作

 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()));

            }
        }

HttpNotificationChannel推送通道；
//我们推送频道的名称。
字符串channelName=“ToastSampleChannel”；
初始化组件（）；
//试着找到推送通道。
pushChannel=HttpNotificationChannel.Find（channelName）；
//如果未找到通道，则创建到推送服务的新连接。
if（pushChannel==null）
{
pushChannel=新的HttpNotificationChannel（通道名称）；
//在尝试打开通道之前注册所有事件。
pushChannel.ChannelUriUpdated+=新事件处理程序（pushChannel\u ChannelUriUpdated）；
pushChannel.ErrorOccursed+=新的事件处理程序（pushChannel\u ErrorOccursed）；
//仅当您需要在应用程序运行时接收通知时，才注册此通知。
pushChannel.ShellToastNotificationReceived+=新事件处理程序（pushChannel\u ShellToastNotificationReceived）；
pushChannel.Open（）；
//为toast事件绑定此新频道。
pushChannel.BindToShellToast（）；
}
其他的
{
//频道已经打开，所以只需注册所有事件。
pushChannel.ChannelUriUpdated+=新事件处理程序（pushChannel\u ChannelUriUpdated）；
pushChannel.ErrorOccursed+=新的事件处理程序（pushChannel\u ErrorOccursed）；
//仅当您需要在应用程序运行时接收通知时，才注册此通知。
pushChannel.ShellToastNotificationReceived+=新事件处理程序（pushChannel\u ShellToastNotificationReceived）；
//出于测试目的显示URI。通常，URI会在此时传递回web服务。
System.Diagnostics.Debug.WriteLine（pushChannel.ChannelUri.ToString（））；
Show（String.Format（“通道Uri为{0}”），
pushChannel.ChannelUri.ToString（））；
}
}

希望它对您有用…如果这里有任何查询而不是评论…

您发布的代码与我使用的MSDN推送通知示例代码相同。
