C# NAudio Trackbar

Question

I'm working with a player with NAudio, refer to http://naudio.codeplex.com/wikipage?title=MP3. Everything worked fine but when I'm coding a trackbar, which show the current time and duration, even can seek into any position of the song, so I used timer to update the current time with mainOutputStream.CurrentTime,but the format is bad to look, then I reformatted it like this:

string curTime = mainOutputStream.CurrentTime.ToString();
string[] format = curTime.Split(':');
format[2] = format[2].Remove(2);
curTime = format[1] + format[2];

but the format[2] = format[2].Remove(2); always return an error. And seems there's no way to get the duration even in timespan but bytes, but I don't like using averageBytePerSecond or anything like this so is there anyway to do these jobs simpler and better? All variable as in the reference above

Thanks.

EDIT: Problems solved~ I used this method:
Get Duration:

string duration = mainOutputStream.TotalTime.ToString("mm\\:ss");
trackPosition.Maximum = (int)mainOutputStream.TotalTime.TotalSeconds;

Get Current Time:

string curTime = mainOutputStream.CurrentTime.ToString("mm\\:ss");
trackPosition.Value = (int)mainOutputStream.CurrentTime.TotalSeconds;

Answer 1

Try this:

string curTimeString = mainOutputStream.CurrentTime.ToString("mm\\:ss");
int curTimeSeconds =  (int)mainOutputStream.CurrentTime.TotalSeconds;

the first one is only formated for minutes and seconds, if your audio tracks are larger you will have to add different formatting.
