C#中播放背景音樂幾種的方法
最經在寫winform程序,其中有用到播放背景音樂
特此收集了一些網上的教程:
1、調用非托管的dll
using System.Runtime.InteropServices; //DllImport命名空間的引用
class test //提示音
{
[DllImport("winmm.dll")]
public static extern bool PlaySound(String Filename,int Mod,int Flags);
public void Main()
{
PlaySound(@"d:/hewenqi.wav",0,1); //把1替換成9,可連續播放
}
}
2、播放系統自帶聲音
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:\hovertree.wav";
sp.PlayLooping();
4、使用MCI Command String多媒體設備程序接口播放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\何問起.mp3"" alias temp_alias", null, 0, 0);
mciSendString("play temp_alias repeat", null, 0, 0);
}
關於mciSendString的詳細參數說明,請參考何問起網
5、使用axWindowsMediaPlayer的COM組件來播放
a.加載COM組件:ToolBox->Choose Items->COM Components->Windows Media Player如下圖:
b.把Windows Media Player控件拖放到Winform窗體中,把axWindowsMediaPlayer1中URL屬性設置為MP3或是AVI的文件路徑,F5運行。
如何使用Windows Media Player循環播放列表中的媒體文件?
假設我們有一個播放列表,下面的代碼可以實現自動循環播放
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\keleyi.avi";
axWindowsMediaPlayer1.Ctlcontrols.play();
}
