winform怎么播放声音?我用了API来播放。当时他要的声音文件的全部地址。比如D:\jxc\bin\Debug\mayfall.wav"
但是我需要的是播放默认文件下的声音。比如~bin\Debug\mayfall.wav"..怎么设置啊。大哥大姐些。跪求。代码如下:
class PlaySoundinfo
{
public static void Play( string strFileName )
{
switch(strFileName)
{
case "back": strFileName = @"bin\Debug\system.wav"; break;
case "fall": strFileName=@"bin\Debug\mayfall.wav"; break;
}
//调用PlaySound方法,播放音乐
Helpers.PlaySound(strFileName, IntPtr.Zero, Helpers.PlaySoundFlags.SND_FILENAME | Helpers.PlaySoundFlags.SND_ASYNC);
}
}
internal class Helpers
{
[Flags]
public enum PlaySoundFlags : int
{
SND_SYNC = 0x0000, /* play synchronously (default) */ //同步
SND_ASYNC = 0x0001, /* play asynchronously */ //异步
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")]
public static extern bool PlaySound(string szSound, IntPtr hMod, PlaySoundFlags flags);
}

具体参数看MSDN
