6.使用directX

1.播放系統事件聲音 

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();
 

SoundPlayer player = new SoundPlayer();
player.SoundLocation = @"D:\test.wav";
player.Load(); //同步載入聲音
player.Play(); //啟用新執行緒播放
//player.PlayLooping(); //迴圈播放模式
//player.PlaySync(); //UI執行緒同步播放

using System.Runtime.InteropServices;

public static class WavPlayer
{
    [DllImport("winmm.dll", SetLastError = true)]
    static extern bool PlaySound(string pszSound, UIntPtr hmod, uint fdwSound);
    [DllImport("winmm.dll", SetLastError = true)]
    static extern long mciSendString(string strCommand, 
        StringBuilder strReturn,int iReturnLength, IntPtr hwndCallback);
    [DllImport("winmm.dll")]
    private static extern long sndPlaySound(string lpszSoundName, long uFlags);

    [Flags]
    public enum SoundFlags
    {
        /// <summary>play synchronously (default)</summary>
        SND_SYNC = 0x0000,
        /// <summary>play asynchronously</summary>
        SND_ASYNC = 0x0001,
        /// <summary>silence (!default) if sound not found</summary>
        SND_NODEFAULT = 0x0002,
        /// <summary>pszSound points to a memory file</summary>
        SND_MEMORY = 0x0004,
        /// <summary>loop the sound until next sndPlaySound</summary>
        SND_LOOP = 0x0008,
        /// <summary>don’t stop any currently playing sound</summary>
        SND_NOSTOP = 0x0010,
        /// <summary>Stop Playing Wave</summary>
        SND_PURGE = 0x40,
        /// <summary>don’t wait if the driver is busy</summary>
        SND_NOWAIT = 0x00002000,
        /// <summary>name is a registry alias</summary>
        SND_ALIAS = 0x00010000,
        /// <summary>alias is a predefined id</summary>
        SND_ALIAS_ID = 0x00110000,
        /// <summary>name is file name</summary>
        SND_FILENAME = 0x00020000,
        /// <summary>name is resource name or atom</summary>
        SND_RESOURCE = 0x00040004
    }

    public static void Play(string strFileName)
    {
        PlaySound(strFileName, UIntPtr.Zero, 
           (uint)(SoundFlags.SND_FILENAME | SoundFlags.SND_SYNC | SoundFlags.SND_NOSTOP));
    }
    public static void mciPlay(string strFileName)
    {
        string playCommand = "open " + strFileName + " type WAVEAudio alias MyWav";
        mciSendString(playCommand, null, 0, IntPtr.Zero);
        mciSendString("play MyWav", null, 0, IntPtr.Zero);

    }
    public static void sndPlay(string strFileName)
    {
        sndPlaySound(strFileName, (long)SoundFlags.SND_SYNC);
    }
}
 

4.使用axWindowsMediaPlayer的COM元件來播放

選擇選單中的“工具”中的“自定義工具箱(新增/移除工具箱項)”，在自定義工具箱的視窗中，點選展開“COM 元件”項，選中“WindowMedia Player”選項。確定後在“工具箱”中便會出現“Windows Media Player”這一項，然後再將其拖至Form上，調整大小，系統在“引用”中自動加入了對此dll的引用，AxMediaPlayer就是我們使用的 Namespace與class。

把Windows Media Player控制元件拖放到Winform窗體中，把axWindowsMediaPlayer1中URL屬性設定為MP3或是AVI的檔案路徑。

private voidmenuItem1_Click(object sender, System.EventArgs e)
{
OpenFileDialogofDialog = new OpenFileDialog();
ofDialog.AddExtension= true;
ofDialog.CheckFileExists= true;
ofDialog.CheckPathExists= true;
//the nextsentence must be in single line
ofDialog.Filter= "VCD檔案(*.dat)|*.dat|Audio檔案(*.avi)|*.avi
  |WAV檔案(*.wav)|*.wav|MP3檔案(*.mp3)|*.mp3|所有檔案 (*.*)|*.*";
ofDialog.DefaultExt= "*.mp3";
if(ofDialog.ShowDialog()== DialogResult.OK)
{
	// 2003一下版本 方法this.axMediaPlayer1.FileName = ofDialog.FileName;
	this.axMediaPlayer1.URL=ofDialog.FileName;//2005用法
}
}

///<summary
/// 播放聲音檔案
/// </summary>
/// <paramname="FileName">檔案全名</param>
public voidPlaySound(string FileName)
{//要載入COM元件: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.SpeechStreamFileMode.SSFMOpenForRead,true);
           SpeechLib.ISpeechBaseStream Istream = spFs as SpeechLib.ISpeechBaseStream;
           pp.SpeakStream(Istream, SpeechLib.SpeechVoiceSpeakFlags.SVSFIsFilename);
           spFs.Close();
}

準備工作：

　　1.安裝了DirectX SDK（有9個DLL檔案）。這裡我們只用到MicroSoft.DirectX.dll 和 Microsoft.Directx.DirectSound.dll

　　2.一個W***檔案。（這樣的檔案比較好找，在QQ的目錄裡就不少啊。這裡就不多說了。）名字叫SND.W***，放在最後目標程式的同個目錄下面

　　開始寫程式啦。隨便用個UltraEdit就好了。

　　1.引入DirectX 的DLL檔案的名字空間：
