            int length = 0;
            int.TryParse(lengthBuf.ToString(), out length);

            return length;

Hello Ayush,

Check this thread out, this might help you.

Regards..

Edited => => => (Another Way)
Following works, check it out
(you'll need to add references to PresentationCore and WindowsBase, you can find them in .NET tab)

C#

MediaPlayer mplayer = new MediaPlayer();
public MainWindow()
{
    InitializeComponent();
}

private void btnPlay_Click(object sender, RoutedEventArgs e)
{
    Uri path = new Uri(@"BigBounce.wav");
    mplayer.Open(path);

    mplayer.Play();

    Thread.Sleep(1000);//if we ommit this, TimeSpan will be NULL, 
    //because for TimeSpan to have a value, file should be playing.
    if (mplayer.NaturalDuration.HasTimeSpan)
    {
        lblLength.Text = mplayer.NaturalDuration.TimeSpan.ToString();
    }           
}

private void btnStop_Click(object sender, RoutedEventArgs e)
{
    mplayer.Stop();
    mplayer.Close();
}
