Question

如何在Windows CE 6.0 R3上调用/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);

它适用于Window XP，7但会抛出一条消息＆＃34;不能P / Invoke winmm.dll＆＃34;在Wnidows CE 6.0上。

我做错了什么？ WaveOut API是移动到其他dll还是其他内容？

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

将winmm.dll更改为coredll.dll，您就完成了！
