C# Thread.Join();Thread.Abort();

Join() 等待当前线程运行完成后，才继续执行主线程后续代码；

Abort() 结束当前线程，继续执行主线程后续代码；

 Thread.Join();

static void Main(string[] args)
        {
            Console.WriteLine("Starting program...");
            Thread t = new Thread(PrintNumbersWithDelay);
            t.Start();
            t.Join();//在继续执行标准的 COM 和 SendMessage 消息泵处理期间，阻塞调用线程，直到某个线程终止为止。
            Console.WriteLine("Thread completed");
            Console.Read();
        }

        static void PrintNumbersWithDelay()
        {
            Console.WriteLine("Starting...");
            for (int i = 1; i < 10; i++)
            {
                Thread.Sleep(TimeSpan.FromSeconds(2));
                Console.WriteLine(i);
            }

            t.Abort();//在调用此方法的线程上引发 System.Threading.ThreadAbortException，以开始终止此线程的过程。调用此方法通常会终止线程。
