IRandomAccessStreamWithContentType stream = null; void OpenSong() { Windows.Storage.KnownFolders.MusicLibrary.GetFileAsync("_.mp3").Completed = (async, status) => { if (async.Status == AsyncStatus.Completed) { StorageFile sf = async.GetResults(); sf.OpenReadAsync().Completed = (async2, status2) => { if (async2.Status == AsyncStatus.Completed) { stream = (IRandomAccessStreamWithContentType)async2.GetResults(); this.Dispatcher.RunAsync(Windows.UI.Core.CoreDispatcherPriority.High, PlaySong).Completed = (async3, status3) => { }; } }; } }; } void PlaySong() { //-Nastavit pouze vlastnost Source nestaci, pak mi to nechtelo hrat, musi se to pres metodu SetSource me.SetSource(stream, stream.ContentType); me.Play(); } |
5. Zavolejte metodu OpenSong() v prazdne metode OnNavigatedTo(). Pokud ji zavolate v konstruktoru, nevyhodi se vam zadna chyba ale zvuk vam proste nebude hrat
