How to play Music using Windows Media player in C #

You first need to add a WMP COM control to the VS2008, and then you can drag the control to the WinForm, and the last code to play is:
This.axWmp.URL = Application.startuppath + "//bg.mp3";
This.axWmp.Ctlcontrols.play ();
Very simple, in addition This.axWmp.Ctlcontrols.XXX there are many ways to control, you can refer to their own.
Of course, you can use This.axWmp.openPlayer (Application.startuppath + //bg.mp3), such code to turn on music playback, but this will pop up a separate WMP window to play.
