C#中播放背景音乐几种的方法
最经在写winform程序,其中有用到播放背景音乐
特此收集了一些网上的教程:
1、调用非托管的dll
using System.Runtime.InteropServices; //DllImport命名空间的引用
class test //提示音
{
[DllImport("winmm.dll")]
public static extern bool PlaySound(String Filename,int Mod,int Flags);
public void Main()
{
PlaySound(@"d:/qm.wav",0,1); //把1替换成9,可连续播放
}
}
2、播放系统自带声音
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、使用System.Media.SoundPlayer播放wav
System.Media.SoundPlayer sp = new SoundPlayer();
sp.SoundLocation = @"D:\10sec.wav";
sp.PlayLooping();
4、使用MCI Command String多媒体设备程序接口播放mp3,avi等
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\青花瓷.mp3"" alias temp_alias", null, 0, 0);
mciSendString("play temp_alias repeat", null, 0, 0);
}
关于mciSendString的详细参数说明,请参见MSDN,或是 http://blog.csdn.net/psongchao/archive/2007/01/19/1487788.aspx
5、使用axWindowsMediaPlayer的COM组件来播放
a.加载COM组件:ToolBox->Choose Items->COM Components->Windows Media Player如下图:
b.把Windows Media Player控件拖放到Winform窗体中,把axWindowsMediaPlayer1中URL属性设置为MP3或是AVI的文件路径,F5运行。
如何使用Windows Media Player循环播放列表中的媒体文件?
假设我们有一个播放列表,下面的代码可以实现自动循环播放
private void axWindowsMediaPlayer1_PlayStateChange(object sender, AxWMPLib._WMPOCXEvents_PlayStateChangeEvent e)
{
if (axWindowsMediaPlayer1.playState == WMPLib.WMPPlayState.wmppsMediaEnded)
{
Thread thread = new Thread(new ThreadStart(PlayThread));
thread.Start();
}
}
private void PlayThread()
{
axWindowsMediaPlayer1.URL = @"E:\Music\SomeOne.avi";
axWindowsMediaPlayer1.Ctlcontrols.play();
}
