You can use WMPLib > Windows Media Player Library

add Windows Media Player reference (References > Add Reference > COM)

and use this code:

using WMPLib;

WindowsMediaPlayer wmp = new WindowsMediaPlayer();
wmp.URL = url; //filepath

wmp.controls.play();

wmp.settings.volume = volume; //(int between 0 to 50)

//get duration as double
WindowsMediaPlayerClass wmpi = new WindowsMediaPlayerClass();
IWMPMedia wmpinfo = wmpi.newMedia(url);
int duration = wmpinfo.duration
//end

wmp.controls.stop();
