C#Thread的Interrupt方法

Interrupt方法，只可以中断处于WaitSleepJoin状态的线程，当线程不为WaitSleepJoin时，线程将恢复执行。

调用Interrupt方法会产生ThreadInterruptException异常

class Program
        {
            static void Main(string[] args)
            {
                StayAwake stayAwake = new StayAwake();
                Thread newThread = new Thread(new ThreadStart(stayAwake.ThreadMethod));
                newThread.Start();
                newThread.Name = "new thread";
                newThread.Interrupt();
                Console.WriteLine("main thread calls interrupt on new thread");
    
                stayAwake.SleepSwitch = true;
                Console.WriteLine("1stat " + Thread.CurrentThread.ThreadState);
                newThread.Join();
            }
        }
    
        class StayAwake
        {
            bool sleepSwitch = false;
    
            public bool SleepSwitch
            {
                set
                {
                    sleepSwitch = value;
                }
            }
    
            public void ThreadMethod()
            {
                Console.WriteLine("new thread is executing thread method");
                while (!sleepSwitch)
                {
                    Thread.SpinWait(10000000);
                }
                try
                {
                    Console.WriteLine("2name " + Thread.CurrentThread.Name);
                    Console.WriteLine("2stat " + Thread.CurrentThread.ThreadState);
                    Console.WriteLine("new thread going to sleep");
                    Thread.Sleep(Timeout.Infinite);
                }
                catch (ThreadInterruptedException e)
                {
                    Console.WriteLine("new thread can not go to sleep -" + "interrupted by main thread");
                }
            }
        }
