c# - 如何在 Web 服务中更新 Windows Phone 8 的磁贴通知？

Question

我开发了一个在 web 服务中获取发票数量的应用程序，它将每 2 分钟在磁贴通知中更新一次。发票编号将在 scheduleAgent.cs 的计数变量中更新。任何想法？

在主页面

ServiceReference1.WebServiceSoapClient test = new ServiceReference1.WebServiceSoapClient();

test.ReadTotalOutstandingInvoiceCompleted += new EventHandler<ServiceReference1.ReadTotalOutstandingInvoiceCompletedEventArgs>(serviceClient);

test.ReadTotalOutstandingInvoiceAsync();


private void serviceClient(object sender, ReadTotalOutstandingInvoiceCompletedEventArgs e)
{
     try
     {
         PeriodicTask p = new PeriodicTask("jj");

         p.Description = "Don't push the red button";

         ScheduledActionService.Add(p);

         ScheduledActionService.LaunchForTest(p.Name, TimeSpan.FromSeconds(10));
     }

     catch(Exception ex)
     {

     }
}

在 ScheduledAgent.cs

 protected override void OnInvoke(ScheduledTask task)
    {
         //TODO: Add code to perform your task in background
         ShellTile t = ShellTile.ActiveTiles.First();

         StandardTileData d = new StandardTileData()
         {
             Title = "asdasdad",

             BackTitle = "cxvxvxvxcv",

             Count = 42,

             BackBackgroundImage = new Uri("dog.jpg", UriKind.Relative),

             BackgroundImage = new Uri("untitled.png", UriKind.Relative)
         };
             t.Update(d);

             NotifyComplete();

    }
