示例1: Run
public void Run(IBackgroundTaskInstance taskInstance)
{
Debug.WriteLine("Background Audio Task " + taskInstance.Task.Name + " starting...");
mdcontrol = BackgroundMediaPlayer.Current.SystemMediaTransportControls;
mdcontrol.IsEnabled = true;
// 允许使用播放/暂停按钮
mdcontrol.IsPlayEnabled = true;
mdcontrol.IsPauseEnabled = true;
// 处理ButtonPressed事件
mdcontrol.ButtonPressed += mdcontrol_ButtonPressed;
// 获取MediaPlayer实例
currentPlayer = BackgroundMediaPlayer.Current;
// 处理事件，接收来自前台应用程序的消息
BackgroundMediaPlayer.MessageReceivedFromForeground += BackgroundMediaPlayer_MessageReceivedFromForeground;
// 关闭自动开始播放
currentPlayer.AutoPlay = false;
// 设置播放源
Uri audioUri = new Uri("ms-appx:///Assets/1.mp3");
currentPlayer.SetUriSource(audioUri);
deferral = taskInstance.GetDeferral();
// 当后台任务被取消时引发事件
taskInstance.Canceled += task_Canceled;
isRunning = true;
