简单多线程与锁

多线程与锁：

namespace Threads
{
    class Program
    {
        static void Main(string[] args)
        {
            Thread[] ths = new Thread[5];
            for (int i = 0; i < ths.Length; i++)
            {
                ths[i] = new Thread(new ThreadStart(Print));
                ths[i].Name = "Thread" + i;
            }

            foreach (Thread th in ths)
            {
                th.Start();
                Thread.Sleep(5);
            }
            Console.ReadLine();
        }

        private static object locked = new object();
        public static void Print()
        {
            lock (locked)
            {
                //显示线程信息。
                Console.WriteLine(Thread.CurrentThread.Name);
                Console.Write("你的号码是：");
                for (int i = 0; i < 5; i++)
                {
                    Thread.Sleep(100 * new Random().Next(5));
                    Console.Write(i+",");
                }
                Console.WriteLine();
            }
        }
    }
}

 

 

简单线程池：

namespace ThreadPool2
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("Main Thread:" + Thread.CurrentThread.ManagedThreadId);

            Print p = new Print();
            WaitCallback back = new WaitCallback(PrintTheNumbers);
            for (int i = 0; i < 5; i++)
            {
                ThreadPool.QueueUserWorkItem(back, p);
            }
            Console.WriteLine("All tasks queued");
            Console.ReadLine();
        }
        public static void PrintTheNumbers(object state)
        {
            Print p = (Print)state;
            p.PrintNumber();
        }

        class Print
        {
            private object locked = new object();
            public void PrintNumber()
            {
                lock (locked)
                {
                    Console.WriteLine("ThreadName:" + Thread.CurrentThread.ManagedThreadId);
                    Console.Write("你的号码是：");
                    for (int i = 0; i < 5; i++)
                    {
                        Console.Write(i + ",");
                        Thread.Sleep(500);
                    }
                    Console.WriteLine();
                }
            }
        }
    }
}
