C# 用API函数调入声音文件

先添加命名空间。using System.Runtime.InteropServices 调用时候用 Sound.Play(文件路径); 文件路径也可以把声音文件放在DEBUG目录下，然后string sound=System.Windows.Forms.Application.StartupPath +@"sound.wav";  调用 Sound.Play(sound);

internal     class    Helpers     {       [Flags]        public     enum    PlaySoundFlags   :    int          {           SND_SYNC    =     0x0000 ,             SND_ASYNC    =     0x0001 ,             SND_NODEFAULT    =     0x0002 ,             SND_MEMORY    =     0x0004 ,             SND_LOOP    =     0x0008 ,            SND_NOSTOP    =     0x0010 ,             SND_NOWAIT    =     0x00002000 ,           SND_ALIAS    =     0x00010000 ,           SND_ALIAS_ID    =     0x00110000 ,           SND_FILENAME    =     0x00020000 ,           SND_RESOURCE    =     0x00040004          }           [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   );       }   }
