windows mobile 下,如何使系统发声?声音文件!

Question

用Miediaplayer控件行吗？至少用API是可以的，不过太麻烦

Answer 1

要是调用.wav 声音文件呢? 也没有这个CoreDll.DLL 呀!
怎么办?

Answer 2

我现在用的是CoreDll.DLL，但是只能播放wav格式的，我想实现的功能是读取到短信铃声，并播放出来.
 
下面的代码完全可以直接使用 
public class Sound
    {
        private byte[] m_soundBytes;
        private string m_fileName;        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 WCE_PlaySound(string szSound, IntPtr hMod, int flags);        [DllImport("CoreDll.DLL", EntryPoint = "PlaySound", SetLastError = true)]
        private extern static int WCE_PlaySoundBytes(byte[] szSound, IntPtr hMod, int flags);        /// <summary>

        /// </summary>
        public Sound(string fileName)
        {
            m_fileName = fileName;
        }
        public Sound()
        { }

            m_soundBytes = new byte[stream.Length];
            stream.Read(m_soundBytes, 0, (int)stream.Length);
        }        /// <summary>

        /// </summary>
        public void Play()
        {
            // if a file name has been registered, call WCE_PlaySound,
            //  otherwise call WCE_PlaySoundBytes
            if (m_fileName != null)
                WCE_PlaySound(m_fileName, IntPtr.Zero, (int)(Flags.SND_ASYNC | Flags.SND_FILENAME));
            else
                WCE_PlaySoundBytes(m_soundBytes, IntPtr.Zero, (int)(Flags.SND_ASYNC | Flags.SND_MEMORY));
        }                public void Stop()
        {
            if (m_fileName != null)
                WCE_PlaySound(null, IntPtr.Zero, (int)(Flags.SND_ASYNC | Flags.SND_FILENAME));
            else
                WCE_PlaySoundBytes(null, IntPtr.Zero, (int)(Flags.SND_ASYNC | Flags.SND_MEMORY));
        }    }
