1、 C#播放声音的四种方法 C#播放声音的四种方法 C#播放声音的四种方法 介绍之前首先推荐一个程序员专用搜索引擎-http:/ 第一种是利用 DirectX 1.安装了 DirectX SDK（有 9 个 DLL 文件）。这里 我 们 只 用 到MicroSoft.DirectX.dll 和 Microsoft.Directx.DirectSound.dll 2.引入 DirectX 的 DLL 文件的名字空间：using Microsoft.DirectX;using Microsoft.DirectX.DirectSound;3.建立设备 Device dv=new Device();4.

2、设置 CooperativeLevel。因为 windows 是多任务的系统，设备不是独占的 SecondaryBuffer buf=new SecondaryBuffer(snd.wav,dv);5.开 辟 缓 冲 区SecondaryBuffer buf=new SecondaryBuffer(snd.wav,dv);6.接下来就可以播放啦。第一个参数表示优先级别，0 是最低的。第 2 个参数是播放方式，这里是循环播放。buf.Play(0,BufferPlayFlags.Looping);第 二 种 是 利 用Microsoft speech object Library /summar

3、y /播放声音文件 /文件全名 public void PlaySound(string FileName)/要加载COM 组件:Microsoft speech object Library if(!System.IO.File.Exists(FileName)return;SpeechLib.SpVoiceClass pp=new SpeechLib.SpVoiceClass();SpeechLib.SpFileStreamClass spFs=new SpeechLib.SpFileStreamClass();spFs.Open(FileName,SpeechLib.SpeechStre

4、amFileMode.SSFMOpenFo rRead,true);SpeechLib.ISpeechBaseStream Istream=spFs as SpeechLib.ISpeechBaseStream;pp.SpeakStream(Istream,SpeechLib.SpeechVoiceSpeakFlags.SVSFIsFilename);spFs.Close();第三种：引用 SoundPlayer System.Media.SoundPlayer sndPlayer=new System.Media.SoundPlayer(Application.StartupPath+/pm

5、3.wav);sndPlayer.PlayLooping();第 4 种：利用 Windows Media Player 新建一个 C#的 Windows Form 工程(Windows 应用程 序)，并 且 定 义 两 个 菜 单 按 钮（menuItem1,menuItem2）。选择菜单中的“工具”中的“自定义工具箱(添加/移除工具箱项)”，在自定义工具箱的窗口中，点击展开“COM 组件”项，选中“Window Media Player”选项。确定后在“工具箱”中便会出现“Windows Media Player”这一项，然后再将其拖至 Form 上，调整大小，系统在“引用”中自动加入了对

6、此 dll 的引用，AxMediaPlayer 就是我们使用的 Namespace 与 class。在属性栏中设置好此控件的一些属性，为了方便，这里我把 AutoStart 设置成为 true（其实默认是 true），只要 FileName 被设置(打开了文件)，则文件将会自动播放。完整代码如下：private void menuItem1_Click(object sender,System.EventArgs e)OpenFileDialog ofDialog=new OpenFileDialog();ofDialog.AddExtension=true;ofDialog.CheckFil

7、eExists=true;ofDialog.CheckPathExists=true;/the next sentence must be in single line ofDialog.Filter=VCD文件(*.dat)|*.dat|Audio 文件(*.avi)|*.avi|WAV文件(*.wav)|*.wav|MP3文件(*.mp3)|*.mp3|所有文件(*.*)|*.*;ofDialog.DefaultExt=*.mp3;if(ofDialog.ShowDialog()=DialogResult.OK)/2003一下版本 方法 this.axMediaPlayer1.FileNa

8、me=ofDialog.FileName;this.axMediaPlayer1.URL=ofDialog.FileName;/2005 用法 这里使用的是微软的播放器，大家也可以试试Winamp 的控件，如果你只需要播放声音而不需要显示，你只要把 AxMediaPlayer 的 Visible 属性设置为 false 就可以了。/Sound.cs /(c)Copyright Jason Clark 2003 /Shows a variety of basic marshalling concepts by making sounds using System;using Wintellect
