c# - 如何在 Win8 C# 应用程序中设置专辑插图？

Question

我希望能够拍摄现有照片并将其设置为专辑插图。

我可以使用 GetThumbnailAsync 给我一个缩略图，并使用 GetOutputStream 获取缩略图输出流。不幸的是，它不可写。

如何在 Win8 C# 应用程序中为项目设置专辑封面(或任何缩略图)？

当前(非工作)代码。当 outStream 因拒绝访问错误而刷新时它会死掉

    FileOpenPicker fileopenpicker = new FileOpenPicker();

    fileopenpicker.FileTypeFilter.Add(".jpg");
    fileopenpicker.FileTypeFilter.Add(".png");

    fileopenpicker.SuggestedStartLocation = PickerLocationId.PicturesLibrary;// | PickerLocationId.DocumentsLibrary | PickerLocationId.PicturesLibrary | PickerLocationId.MusicLibrary;

    var singlefileoperation = await fileopenpicker.PickSingleFileAsync();
    var read = await singlefileoperation.OpenAsync(FileAccessMode.Read);

    StorageFile replay = currentlyPlaying;
    TimeSpan pos = ME.Position;
    ME.Stop();

    //curren
    StorageItemThumbnail storageItemThumbnail = await currentlyPlaying.GetThumbnailAsync(ThumbnailMode.SingleItem);




    IOutputStream inputStreamAt = storageItemThumbnail.GetOutputStreamAt(0);
    Stream outStream = inputStreamAt.AsStreamForWrite();

    var inStreamAt = read.GetInputStreamAt(0);
    var inStream = inStreamAt.AsStreamForRead();
    await inStream.CopyToAsync(outStream);
    await outStream.FlushAsync();
    outStream.Dispose();
    inStream.Dispose();
    inStreamAt.Dispose();

TagLib Sharp应该对您正在寻找的内容有所帮助。

TagLib.File tagFile = TagLib.File.Create(c:/yourpath/yoursong.mp3);
IPicture newArt = new Picture(c:/yourimagepath/youralbumart.jpg);
tagFile.Tag.Pictures = new IPicture[1] {newArt};
tagFile.Save();
