问题
I am using TagLib (UltraID3Lib couldn't read every MP3 file). Maybe TagLib will do. And I couldn't find properties like Subtitle or Duration or Time?
How do I find this kind of tags?
Example: "Ondertitel" means Subtitle

回答1:
This way, you can get the duration:
var file = TagLib.File.Create(@"xyz.mp3");
Console.WriteLine(file.Properties.Duration);
