WinPhone 媒体播放器

Question

我正在尝试创建一些媒体播放器，但此时已堆叠。需要将一些文件添加到我的播放列表，但它抛出异常...这是代码

private async void Open_OnClick(object sender, RoutedEventArgs e)
        {
            var openPicker = new FileOpenPicker
            {
                ViewMode = PickerViewMode.Thumbnail,
                SuggestedStartLocation = PickerLocationId.PicturesLibrary
            };
            openPicker.FileTypeFilter.Add(".mp3");
            var selectedFiles = await openPicker.PickMultipleFilesAsync();
            if (selectedFiles != null)
            {
                foreach (StorageFile file in selectedFiles)
                {
                    Playlist.Add(file.Path);
                }
            }

        }

异常

An exception of type 'System.Exception' occurred in MediaPlayer.exe but was not handled in user code Additional information: The request is not supported. (Exception from HRESULT: 0x80070032)

Answer 1

根据文档 FileOpenPicker.PickMultipleFilesAsync() 未在 Windows Phone 8 API 中实现，您至少需要 Windows 10 才能使用它。
