Question

我有一个mp3文件，我想添加专辑封面。艺术品已被保存到临时文件夹中，我已经检查了这个并且它就在那里并且是一个jpeg。这是我给出的代码：

        public void AddMp3Tags()
        {
            TagLib.File file = TagLib.File.Create(OutputPath + OutputName + "." + Format);
            SetAlbumArt(Art, file);
            file.Tag.Title = SongTitle;
            file.Tag.Performers = Artists.Split(',');
            file.Tag.Album = Album;           
            file.Tag.Track = (uint)TrackNumber;
            file.Tag.Year = (uint)Convert.ToInt32(Regex.Match(Year, @"(\d)(\d)(\d)(\d)").Value);            
            file.Save();
        }

        public void SetAlbumArt(string url, TagLib.File file)
        {     
            string path = string.Format(@"{0}temp\{1}.jpg", OutputPath, Guid.NewGuid().ToString());
            using (WebClient client = new WebClient())
            {

                client.DownloadFile(new Uri(url), path);
            }


            TagLib.Picture pic = new TagLib.Picture
            {
                Type = TagLib.PictureType.FrontCover,
                Description = "Cover",
                MimeType = System.Net.Mime.MediaTypeNames.Image.Jpeg
            };
            MemoryStream ms = new MemoryStream();
            Image image = Image.FromFile(path);
            image.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg);
            ms.Position = 0;
            pic.Data = TagLib.ByteVector.FromStream(ms);
            file.Tag.Pictures = new TagLib.IPicture[] { pic };
            file.Save();
            ms.Close();

        }

除了显示黑匣子的艺术作品外，所有标签都设置正确： Black box cover art in windows media player.

我尝试了很多东西，我做错了什么？

确保您的文件已成功下载并尝试此操作：

public void SetAlbumArt(string url, TagLib.File file)
{     
    string path = string.Format(@"{0}temp\{1}.jpg", OutputPath, Guid.NewGuid().ToString());
    using (WebClient client = new WebClient())
    {

        client.DownloadFile(new Uri(url), path);
    }

    file.Tag.Pictures = new TagLib.IPicture[]
    {
        new TagLib.Picture(new TagLib.ByteVector((byte[])new System.Drawing.ImageConverter().ConvertTo(System.Drawing.Image.FromFile(path), typeof(byte[]))))
        {
            Type = TagLib.PictureType.FrontCover,
            Description = "Cover",
            MimeType = System.Net.Mime.MediaTypeNames.Image.Jpeg
        }
    };

    file.Save();
}
