C#播放背景音乐通常有四种方式:
1.播放系统事件声音
2.使用System.Media.SoundPlayer播放wav------------------------仅仅是对波形音乐
3.使用MCI Command String多媒体设备程序接口播放mp3,avi等
4.使用axWindowsMediaPlayer的COM组件来播放
1.播放系统事件声音
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();
2.使用System.Media.SoundPlayer播放wav
System.Media.SoundPlayer sp = new SoundPlayer(); sp.SoundLocation = @"D:/10sec.wav"; sp.PlayLooping();
3.使用MCI Command String多媒体设备程序接口播放mp3,avi等
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Runtime.InteropServices; namespace MyWenxinTool { public class musicplay { 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 static void PlayNmusinc(string path) { mciSendString(@"close temp_alias", null, 0, 0); mciSendString(@"open """+path+@""" alias temp_alias", null, 0, 0); mciSendString("play temp_alias repeat", null, 0, 0); } /// <summary> /// 播放音乐文件(重复) /// </summary> /// <param name="p_FileName">音乐文件名称</param> public static void PlayMusic_Repeat(string p_FileName) { try { mciSendString(@"close temp_music", " ", 0, 0); mciSendString(@"open " + p_FileName + " alias temp_music", " ", 0, 0); mciSendString(@"play temp_music repeat", " ", 0, 0); } catch { } } /// <summary> /// 播放音乐文件 /// </summary> /// <param name="p_FileName">音乐文件名称</param> public static void PlayMusic(string p_FileName) { try { mciSendString(@"close temp_music", " ", 0, 0); //mciSendString(@"open " + p_FileName + " alias temp_music", " ", 0, 0); mciSendString(@"open """ + p_FileName + @""" alias temp_music", null, 0, 0); mciSendString(@"play temp_music", " ", 0, 0); } catch { } } /// <summary> /// 停止当前音乐播放 /// </summary> /// <param name="p_FileName">音乐文件名称</param> public static void StopMusic(string p_FileName) { try { mciSendString(@"close " + p_FileName, " ", 0, 0); } catch { } } } }
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
4.使用axWindowsMediaPlayer的COM组件来播放
a.加载COM组件:添加引用-->Com组件--> 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
MediaPlayer.MediaPlayer mr = new MediaPlayer.MediaPlayer(); mr.FileName = txpath.Text.Trim(); mr.Play();
MCI Command String和Windows Media Player都有非常丰富的功能接口,这里不能一一介绍,可以参考MSDN中的具体描述.
