C#在主界面中创建了两个线程，如何在主界面的按钮按下时关闭线程1

Question

如题。

Answer 1

在线程对象上调用Abort()即可在线程中引发异常，然后在线程中捕获到该异常后做退出线程的处理。

1楼太糊弄人了吧！！ static volatile bool flag=false ;
        static void run() 
        {
            while (!flag) 
            {
                Console.WriteLine("run");
                Thread.Sleep(1000);
            }        }
   Thread t = new Thread(run);
            t.Start();
            int i=0;
            while (i<10)
            {
                Thread.Sleep(1000);
                i++;
            }
            flag = true;
            t.Join();
            Console.WriteLine("Complete");
            Console.Read();
