The most written WinForm program, which is useful to play background music

Here are some online tutorials:

1. Calling unmanaged DLLs

?

1 2 3 4 5 6 7 8 9 10 11-12

Using System.Runtime.InteropServices; DllImport namespace Reference class Test//Beep {[DllImport ("Winmm.dll")] public static extern bool PlaySound (String filename,int Mod , int Flags); public void Main () {PlaySound (@ "D:/qm.wav", 0, 1);///replace 1 with 9 for continuous playback}}

2. Playback system with sound

?

1 2 3 4 5

System.Media.SystemSounds.Asterisk.Play (); System.Media.SystemSounds.Beep.Play (); System.Media.SystemSounds.Exclamation.Play (); System.Media.SystemSounds.Hand.Play (); System.Media.SystemSounds.Question.Play ();

3. Use System.Media.SoundPlayer to play WAV

?

1 2 3

System.Media.SoundPlayer sp = new SoundPlayer (); Sp. Soundlocation = @ "D:10sec.wav"; Sp. Playlooping ();

4. Use MCI Command string Multimedia Device program interface to play Mp3,avi, etc.

Using System.Runtime.InteropServices; public static UINT Snd_async = 0x0001; public static UINT snd_filename = 0x00020000; [DllImport ("Winmm.dll")] public static extern uint mciSendString (string lpstrcommand, String lpstrreturnstring, uint Ureturnlength, uint hwndcallback); public void Play () {mcisendstring (@ "Close Temp_alias", NULL, 0, 0); mciSendString (@ "open" "E:music blue and White porcelain. mp3" "Alias Temp_al IAS ", null,0,0); mciSendString ("Play Temp_alias repeat", NULL, 0, 0); }

For detailed parameter descriptions on mcisendstring, see MSDN, or Http://blog.csdn.net/psongchao/archive/2007/01/19/1487788.aspx

5, using the AxWindowsMediaPlayer COM components to play

Let's say we have a playlist and the following code can be used to loop automatically

?

private void Axwindowsmediaplayer1_playstatechange (object sender, Axwmplib._wmpocxevents_playstatechangeevent e) {if (axwindowsmediaplayer1.playstate = = WMPLib.WMPPlayState.wmppsMediaEnded) {Thread thread = new Thread (new ThreadStart (Playthread)); Start (); } private void Playthread () {Axwindowsmediaplayer1.url = @ "E:musicsomeone.avi"; AxWindowsMediaPlayer1.Ctlcontrols.play (); }

I hope this article will help you with the C # program.
