调用的参数和VB中一样[DllImport("user32.dll")] private static extern int MessageBeep(int type) ;
这个可以播WAV,调用时Sound.Play(FILE_NAME);internal class Helpers { [Flags] public enum PlaySoundFlags : int { 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("winmm.dll")] public static extern bool PlaySound( string szSound, IntPtr hMod, PlaySoundFlags flags ); } public class Sound { public static void Play( string strFileName ) { Helpers.PlaySound( strFileName, IntPtr.Zero, Helpers.PlaySoundFlags.SND_FILENAME | Helpers.PlaySoundFlags.SND_ASYNC ); } }
