C# 怎样通知另外一个线程该干什么了

[mrnian2008]

打个比方，我建一个窗体Form1，含两个按扭控件button1和button2，点击button1时，开启线程Thread1，该线程开始录音并写Wav文件，当我点击button2时，想让该线程停止录音并写Wav文件尾。问題：怎样让Thread1接收到button2的命令？

让每个线程有个自己的消息队列

点击button2是主线程命令，使用委托 操作thread1线程

关注中，我和楼主有同样的疑惑

设置一个标记位
bool flag = true
当Thread1中录音并写Wav文件必定是个迭代 那么在这个迭代中判断标记位是否为TURE，为TRUE就继续执行
为FALSE则推出循环 当然在退出时你可以记录当前的一些参数 一共你可以继续！

这样你要在点击utton2是停止他就很容易了，我想你也看出来了，把flag职位FALSE就可以了！

private bool flag = true吧

                Thread.Sleep(1000);
            }

            e.Result = 123;
        }
    }

用BackgroundWorker，参考Console程序,改成你要的WinForm即可

正确的做法是使用信号量http://www.cnblogs.com/luminji/archive/2010/09/17/1829360.html
