你在使用Stream做什么？似乎没什么。您正在尝试两次创建该文件。尝试删除流：

private void UpdateTagEditor_RegisterActionEventHandler(object sender, RoutedEventArgs e)
{
    var tags = sender as UpdateTags;
    string path = tags.targetPath;
    string comments = tags.txtTagComment.Text;
    string lyrics = tags.txtTagLyrics.Text;
    try
    {
        TagLib.Id3v2.Tag.DefaultVersion = 3;
        TagLib.Id3v2.Tag.ForceDefaultVersion = true;
        TagLib.File tagFile = TagLib.File.Create(path);
        tagFile.Tag.Comment = comments;
        tagFile.Tag.Lyrics = lyrics;
        tagFile.Save();
    }
    catch (Exception exception)
    {

    }
}
