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,请高手帮帮忙。

 

代码
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>
/// Construct the Sound object to play sound data from the specified file.
/// </summary>
public Sound(string fileName)
{
m_fileName
= fileName;
}
public Sound()
{ }
/// <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);
}

/// <summary>
/// Play the sound
/// </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));
}

}

 

 

另外,我在网上也看到了下面的方法,但是,只能在winform里面使用,我想在mobile上用改怎么办呢。

代码
