我想用线程开起音乐，但怎么能让它停止呢

[yinjianjing]

我现在的问题就是无论如何，只要用线程开起的音乐，就关闭不了音乐播放，应该怎么办呢，

以下是测试代码
Audio a;
Thread t;
private void button1_Click(object sender, EventArgs e)
{
t = new Thread(new ThreadStart(abc));

t.Start();
a = new Audio();

}
private void abc()
{
while (true)
{
a.Play(@"F:\TT\ZhiLi\ZhiLi\ZhiLi\bin\Debug\wav\2-5.wav");

Thread.Sleep(50);
}
}

private void button3_Click(object sender, EventArgs e)
{
a.Stop();

}

音乐类
public class Audio
{
[DllImport("winmm.dll")]
private static extern int mciSendString
(
string lpstrCommand,
string lpstrReturnString,
int uReturnLength,
int hwndCallback
);

[DllImport("kernel32.dll", CharSet = CharSet.Auto)]
public static extern int GetShortPathName
(
[MarshalAs(UnmanagedType.LPTStr)] string path,
[MarshalAs(UnmanagedType.LPTStr)] StringBuilder shortPath,
int shortPathLength
);

public Audio()
{

}

public void Play(string FileName)
{
StringBuilder shortPathTemp = new StringBuilder(255);
int result = GetShortPathName(FileName, shortPathTemp, shortPathTemp.Capacity);
string ShortPath = shortPathTemp.ToString();

mciSendString("open " + ShortPath + " alias song", "", 0, 0);

mciSendString("play song", "", 0, 0);
}

public void Stop()
{
mciSendString("stop song", "", 0, 0);
mciSendString("close song", "", 0, 0);
}

public void Pause()
{
mciSendString("pause song", "", 0, 0);
}

public void Close()
{
mciSendString("close song", "", 0, 0);
}
}



我现在的需求是我想FORM窗口初始化的时候，边创建控件边播放音乐，如果不用线程的话它只会播放完音乐后才能显示界面

如何我必须要用线程怎么办呢

给 死循环 加个 bool 变量 来判断时候停止
stop 里面改变变量

[yinjianjing]

while (true)
你是说这个用变量吗，没用，我试过了

关掉那个线程a .Abort();

[li45214521]

while (true)
{
if(isPlay)
{
a.Play(@"F:\TT\ZhiLi\ZhiLi\ZhiLi\bin\Debug\wav\2-5.wav");
}
if(isStop)
{
a.Stop();
break;
}
Thread.Sleep(50);
}

3楼正解，关掉线程，在适当的地方加t.Abort(),建议把线程创建及线程对象都封装到音乐类里面

真的学习了。...~~~

[bloodish]

        AutoResetEvent stopEvent = new AutoResetEvent(false);
        private void abc()
        {
            while (!stopEvent.WaitOne(50))
            {
                a.Play(@"F:\TT\ZhiLi\ZhiLi\ZhiLi\bin\Debug\wav\2-5.wav");            
            }
        }   
         public void Close()
         {
             stopEvent.Set();
         }

直接把线程关了

我也遇到这个问题了，到底要怎么解决啊？
