即使启用了 broadFileSystemAccess 也无法访问文件

Question

我有一个关联了文本和音频文件的 UWP 桌面应用程序，例如，当用户选择 Class1.txt 文件时，该应用程序会自动尝试打开 Class1.mp3 文件。即使配置了 broadFileSystemAccess，该操作始终 returns 访问被拒绝错误。欢迎任何帮助。谢谢

private async void nviOpen_Tapped(object sender, TappedRoutedEventArgs e)
{
    FileOpenPicker openPicker = new FileOpenPicker();
    openPicker.ViewMode = PickerViewMode.Thumbnail;
    openPicker.SuggestedStartLocation = PickerLocationId.DocumentsLibrary;
    openPicker.FileTypeFilter.Add(".txt");

    StorageFile file = await openPicker.PickSingleFileAsync();

    if (file != null)
    {
        try
        {
            using (var txtStream = await file.OpenStreamForReadAsync())
            {
                var encoding = FileEncoding.DetectFileEncoding(txtStream);
                txtStream.Seek(0, SeekOrigin.Begin);
                var stmReader = new StreamReader(txtStream, encoding);
                var txtContent = await stmReader.ReadToEndAsync();

                tbxOriginalText.Text = txtContent;
            }

            //Open associated audio file
            var audioFile = await StorageFile.GetFileFromPathAsync(file.Path + @"\" + file.DisplayName + ".mp3");

            if (audioFile != null)
            {
                MediaPlaybackItem mediaPlaybackItem = new MediaPlaybackItem(MediaSource.CreateFromStorageFile(audioFile));
            }
        }
        catch (Exception ex)
        {
            MessageDialog msgDlg = new MessageDialog(ex.Message);
            await msgDlg.ShowAsync();
        }
    }
}

请查看文件系统隐私设置，确保您已允许您的应用访问您的文件系统。
