C#聲音控制

不能用控件，防止播放的時候出現延時
或者能夠提供內存方法存放聲音數據
目的就是能夠十分准確的播放聲音，不會出現聲音的延遲現象

[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添加入工程並設置為嵌入的資源
//現在是將它讀入內存備用
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);
