在 Windows Phone 7 中设置闹钟

问题描述

在我的应用程序 Application_Exit 事件中，我尝试使用 ScheduledActionService 设置警报.这在其他代码中工作正常，但在这里它不断抛出带有消息 E_INVALIDARG

In my application Application_Exit event i am trying to set an alarm using the ScheduledActionService. This works fine in other code but here it keeps throwing an argumentexception with message E_INVALIDARG

这是代码

 string alarmName = Guid.NewGuid().ToString();
 const string cookingClockAlarm = "Cooking clock alarm";
 DateTime dueTime = DateTime.Now.AddSeconds(10);
 var alarm = new Alarm(alarmName)
                    {
                        Content = cookingClockAlarm,
                        BeginTime = dueTime,
                        ExpirationTime = dueTime.AddSeconds(3),
                        RecurrenceType = RecurrenceInterval.None
                    };
 // Register the alarm with the system.
 ScheduledActionService.Add(alarm);//here I get an exception

知道我在这里做错了什么吗?

Any ideas what I am doing wrong here?

推荐答案

我在 Application_Closing 方法中添加了这段代码，但它没有抛出错误.似乎在退出事件中安排闹钟为时已晚.

I added this code in the Application_Closing method and it didn't throw an error. Seems like in the Exit event it is too late to do schedule an alarm.
