C#中编写多线程（1）——起步

    
            for (int i = 0; i < 4; i++) {
                Console.WriteLine("Main thread: Do some work.");
                Thread.Sleep(0);
            }
   
            Console.WriteLine("Main thread: Call Join(), to wait until ThreadProc ends.");
            t.Join();
            Console.WriteLine("Main thread: ThreadProc.Join has returned.  Press Enter to end program.");
            Console.ReadLine();
        }
    }

   
       此代码产生的输出类似如下内容：

    Main thread: Start a second thread.
    Main thread: Do some work.
    ThreadProc: 0
    Main thread: Do some work.
    ThreadProc: 1
    Main thread: Do some work.
    ThreadProc: 2
    Main thread: Do some work.
    ThreadProc: 3
    Main thread: Call Join(), to wait until ThreadProc ends.
    ThreadProc: 4
    ThreadProc: 5
    ThreadProc: 6
    ThreadProc: 7
    ThreadProc: 8
    ThreadProc: 9
    Main thread: ThreadProc.Join has returned.  Press Enter to end program.
