Question

我有一个Windows Phone市场营销应用。用户报告应用程序有时会在Windows Phone 8崩溃。以下是来自Windows Phone开发中心报告的数据：

问题功能：

Microsoft.Phone.Scheduler.SystemNotificationInterop.CheckHr

异常类型

system.reflection.targetinvocationexception

堆栈追踪：

Frame    Image                 Function                                                                  Offset

2        microsoft_phone_ni    Microsoft.Phone.Scheduler.ScheduledActionService.Add                      0x00000056

问题可能出在后台代理上。我使用过these tutorial。

我的代码：

public MainPage()
    {
        InitializeComponent();

        /* Periodic agents*/
            // A unique name for your task. It is used to  
            // locate it in from the service. 
            var taskName = "MyTask";

            // If the task exists 
            var oldTask = ScheduledActionService.Find(taskName) as PeriodicTask;
            if (oldTask != null)
            {
                ScheduledActionService.Remove(taskName);
            }

            // Create the Task 
            PeriodicTask task = new PeriodicTask(taskName);

            // Description is required 
            task.Description = "This saves some data to Isolated Storage";

            // Add it to the service to execute 
            ScheduledActionService.Add(task);

          /* Testing my agent*/
         //   ScheduledActionService.LaunchForTest(taskName, TimeSpan.FromMilliseconds(1500));
           /* Testing my agent*/

        /* Periodic agents */
...

我恳求ScheduledActionService.Find throws ArgumentException，但背后没有想法

您必须将定期代理代码放在Application_Closing

中的方法内的App.xaml.cs中
