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一http://www・ openso・ net 第一种是利用DirectX1.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.设置CooperativeLevel o 因为windows 是多任务的系统，设备不是独占的SecondaryBufferbuf=new SecondaryBuffer(@"snd・ wav", dv);5.开辟缓冲区SecondaryBuffer buf=newSecondaryBuffer (@/z 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, BufferP1ayFlags・ Looping); 第二种是利用Microsoft speech objectLibrary/// <summaryIII播放声音文件III </summary〉III <param name二"FileName">文件全名</param>public void PlaySound(string FileName){//要加载COM 组件:Microsoft speech object Library(!System. I0・ File・ Exists(FileName))return;SpeechLib・ SpVoiceClass pp 二new SpeechLib・ SpVoiceClass();SpeechLib・ SpFileStreamClass spFs = new SpeechLib・SpFileStreamClass();spFs・ Open(FileName,SpeechLib・ SpeechStreamFileMode・ SSFMOpenFo rRead, true);SpeechLib・ISpeechBaseStream1stream = spFs as SpeechLib・ISpeechBaseStream;pp・ SpeakStream(lstream, SpeechLib・ SpeechVoiceSpeakFlags・ SVSFIsFil ename);spFs・ Close ();第三种：引用SoundPlayerSystem・ Media・ SoundPlayer sndPlayer = new System・ Media・ SoundPlayer(Application. Star tupPath+@/z/pm3. 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（menu It eml, menult em2）。
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a 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 menulteml_Click(object sender, System・ EventArgs e)OpenFileDialog ofDialog OpenFileDialog();new ofDialog. AddExtension 二true; ofDialog・CheckF订eExists = true; ofDialog・CheckP且thExists = true;//the next sentence must be in single line ofDialog.

OK)方法// 2003 一下版本t his. axMe d i aP 1 ay er 1 • FilofDialog・ FileName;this・ axMediaPlayer1・ URL二ofDialog. FileName: //2005 用法这里使用的是微软的播放器，大家也可以试试要显示，你只要把AxMediaPlayer的Visible属性设置为false就可以了。
