C# getting mp3 file length

C# getting mp3 file length

I am currently trying to write an Audio Player in C#. I am using BASS
liblary to deal with playing music but now i have small problem with
getting length of the song.
Well i have read BASS doc and found a way: "All" i need to do is
int stream = Bass.BASS_StreamCreateFile(filepath,....);
int length = Bass.BASS_ChannelBytes2Seconds(stream,
Bass.BASS_ChannelGetLength(stream));
And in most of cases i get valid length of song. And here the problem
starts. As far as i know the stream creation operation is quite expensive
(correct me if i am mistaken) and creating a stream only to get length of
the song looks a little silly.
So my question is: Is there any other way to get it without creating steam
file (not being so expensive). I will be thinking later about reading id3
tags. Is creating that stream "evil that must be done no matter what" and
even if i would try to get it with other liblary it would do exactly the
same thing?
