//线程同步与多线程程序中的隐患
namespace Multithreading_hazard
{
    class Program
    {
        private static int stickets = 100;
        static void Main(string[] args)
        {
            Thread thread1 = new Thread(SaleTicketThread1);
            Thread thread2 = new Thread(SaleTicketThread2);
            thread1.Start();
            thread2.Start();
            Thread.Sleep(4000);
        }

        private static void SaleTicketThread1()
        {
            while (true)
            {
                if (stickets>0)
                {
                    Console.WriteLine("线程一出票{0}:", stickets--);
                }
                else
                {
                    break;
                }
            }
        }
        private static void SaleTicketThread2()
        {
            while (true)
            {
                if (stickets > 0)
                {
                    Console.WriteLine("线程二出票{0}:", stickets--);
                }
                else
                {
                    break;
                }
            }
        }
    }

}

因为两个线程访问了同一个静态变量stickets,线程出票的顺序发生了变化,将会引起数据出现错误.

为了避免这种情况的发生，保证同一时间类只有一个线程访问共享资源;

使用:线程同步:C# Monitor与线程同步
