audio - 如何在Windows CE 6.0 R3上P/调用WaveOut API

Question

如何在Windows CE 6.0 R3上P /调用WaveOut API？

当我把这个

[DllImport("winmm.dll", SetLastError = true, CharSet = CharSet.Auto)]
public static extern MMRESULT waveOutOpen(ref IntPtr hWaveOut, int uDeviceID, ref WAVEFORMATEX lpFormat, DelegateWaveOutProc dwCallBack, int dwInstance, int dwFlags);

[DllImport("winmm.dll")]
public static extern MMRESULT waveInOpen(ref IntPtr hWaveIn, int deviceId, ref WAVEFORMATEX wfx, DelegateWaveInProc dwCallBack, int dwInstance, int dwFlags);

[DllImport("winmm.dll", SetLastError = true)]
public static extern MMRESULT waveInStart(IntPtr hWaveIn);

[DllImport("winmm.dll", SetLastError = true, CharSet = CharSet.Auto)]
public static extern uint waveInGetDevCaps(int index, ref WAVEINCAPS pwic, int cbwic);

[DllImport("winmm.dll", SetLastError = true)]
public static extern uint waveInGetNumDevs();

[DllImport("winmm.dll", SetLastError = true, CharSet = CharSet.Auto)]
public static extern uint waveOutGetDevCaps(int index, ref WAVEOUTCAPS pwoc, int cbwoc);

[DllImport("winmm.dll", SetLastError = true)]
public static extern uint waveOutGetNumDevs();

[DllImport("winmm.dll", SetLastError = true, CharSet = CharSet.Auto)]
public static extern MMRESULT waveOutWrite(IntPtr hWaveOut, ref WAVEHDR pwh, int cbwh);

[DllImport("winmm.dll", SetLastError = true, CharSet = CharSet.Auto)]
public static extern MMRESULT waveOutPrepareHeader(IntPtr hWaveOut, ref WAVEHDR lpWaveOutHdr, int uSize);

它可以在Windows XP 7上运行，但在Wnidows CE 6.0上抛出一条消息“无法P /调用winmm.dll”。

我究竟做错了什么？ WaveOut API是否已移至其他dll或其他？

无论如何，SoundPlayer(来自.NET Compact Framework 3.5)都可以正常工作。

将winmm.dll更改为coredll.dll，您就完成了!
