在PPC上播放聲音不像在PC上可以直接使用vs2005給提供的System.media命名空間中的方法.而只能調(diào)用外部的coredll.dll庫(kù).只能播放.wav文件,并且還不是所有的都能播,但現(xiàn)在我也沒(méi)有發(fā)現(xiàn)還有其他的辦法.

以下是播放聲音的代碼:
?class Sound
??? {
??????? private byte[] m_soundBytes;
??????? private enum Flags
??????? {
??????????? SND_SYNC = 0x0000,? /* play synchronously (default) */
??????????? SND_ASYNC = 0x0001,? /* play asynchronously */
??????????? SND_NODEFAULT = 0x0002,? /* silence (!default) if sound not found */
??????????? SND_MEMORY = 0x0004,? /* pszSound points to a memory file */
??????????? SND_LOOP = 0x0008,? /* loop the sound until next sndPlaySound */
??????????? SND_NOSTOP = 0x0010,? /* don't stop any currently playing sound */
??????????? SND_NOWAIT = 0x00002000, /* don't wait if the driver is busy */
??????????? SND_ALIAS = 0x00010000, /* name is a registry alias */
??????????? SND_ALIAS_ID = 0x00110000, /* alias is a predefined ID */
??????????? SND_FILENAME = 0x00020000, /* name is file name */
??????????? SND_RESOURCE = 0x00040004? /* name is resource name or atom */
??????? }

??????? [DllImport("CoreDll.DLL", EntryPoint = "PlaySound", SetLastError = true)]
??????? private extern static int MobilePlaySound(string szSound, IntPtr hMod, int flags);//播放外部聲音文件

??????? [DllImport("CoreDll.DLL", EntryPoint = "PlaySound", SetLastError = true)]
??????? private extern static int MoiblePlaySoundBytes(byte[] szSound, IntPtr hMod, int flags);//播放嵌入聲音資源

??????
??????? /// <summary>
??????? /// Construct the Sound object to play sound data from the specified stream.
??????? /// </summary>
??????? public Sound(Stream stream)
??????? {
??????????? // read the data from the stream
??????????? m_soundBytes = new byte[stream.Length];
??????????? stream.Read(m_soundBytes, 0, (int)stream.Length);
??????? }

??????? public Sound(byte [] snd)
??????? {
??????????? m_soundBytes =snd;
??????? }

??????? /// <summary>
??????? /// Play the sound
??????? /// </summary>
??????? public void Play()
??????? {

??????????? MoiblePlaySoundBytes(Properties.Resources.notify, IntPtr.Zero, (int)(Flags.SND_ASYNC | Flags.SND_FILENAME));
??????? }
Properties.Resources.notify這個(gè)是我的嵌入聲音資源，源文件是notify.wav，這個(gè)也是我自己改的，用ＭＳＤＮ上提供的代碼，我怎么也播不出聲音來(lái)．
