不能用控件，防止播放的時候出現(xiàn)延時
或者能夠提供內(nèi)存方法存放聲音數(shù)據(jù)
目的就是能夠十分準(zhǔn)確的播放聲音，不會出現(xiàn)聲音的延遲現(xiàn)象

[dllimport("winmm.dll")]
public static extern long playsound(string name,long  module,long flag);
[dllimport("winmm.dll")]
private static extern long mcisendstring(string lpstrcommand,string lpstrreturnstring,long length,long hwndcallback);
private string m_musicname="";
private void playmusic()
{
 m_musicname="/""+tool.readinfo("promptmusicfile")+"/"";
 if(m_musicname.length==0)
 return;
 try
 {
 mcisendstring(@"close " + m_musicname,"",0,0);
 mcisendstring(@"open " + m_musicname,"",0,0);
 mcisendstring(@"play " + m_musicname ,"",0,0);
 }
 catch
 {
 }

}

private void stopmusic()
{
 try
 {
 mcisendstring(@"close " + m_musicname,"",0,0);
 }
 catch{}
}

播放內(nèi)存中的wav文件可以這樣：

//api定義
private const int snd_async  = 0x1;
private const int snd_memory = 0x4;

[dllimport("winmm.dll")]
private static extern int sndplaysounda(byte[] lpszsoundname, int uflags);

//將blip1.wav添加入工程并設(shè)置為嵌入的資源
//現(xiàn)在是將它讀入內(nèi)存?zhèn)溆?br>type t=this.gettype();
system.reflection.assembly a=t.assembly;
system.io.stream stream=a.getmanifestresourcestream(t.namespace+".blip1.wav");
byte[] ba=new byte[stream.length];
stream.read(ba,0, ba.length);
stream.close();

//播放緩存
sndplaysounda(ba, snd_memory);
