学习笔记线程的几个常用方法实例

网上找到的一段代码，经过自己的些微修改，方便理解线程中常用的sleep，join，abort用法

class Program
    {
        public static void doSomething()
        {
            for (int i = 0; i < 100; i++)
            {

　　　　　　//当前进程每打印一个数字就等待100毫秒钟
                Console.WriteLine("doSomething thread:{0}.", i);
                Thread.Sleep(100);

　　　　　　//如果i=50，则当前进程终止
                if (i == 50)
                {
                    Thread.CurrentThread.Abort();
                }
            }
        }

        static void Main(string[] args)
        {
            //thread.sleep,join,abort执行
           //开始主进程

　　　　try
            {
                //Thread.CurrentThread.Abort();//此句当前主进程终止，退出程序
                ThreadStart startThread = new ThreadStart(doSomething);
                Thread newThread = new Thread(startThread);
                newThread.Start();//子进程开始
                for (int i = 0; i < 50; i++)
                {

　　　　　　　　//主进程每打印一个数字就等待100毫秒钟
                    Console.WriteLine("mainThread:{0}.", i);
                    Thread.Sleep(100);

　　　　　　　　//当i=25的时候，子进程加入到主进程中来，子进程此时输出到25这个数字
                    if (i == 25)
                    {
                        newThread.Join();
                    }

　　　　　　　　//主进程等待子进程执行完毕，才会接着向下执行

　　　　　　　　//当i=40的时候，主线程终止，此时进入到catch块
                    if (i == 40)
                    {
                        Thread.CurrentThread.Abort();
                    }
                }
            }
            catch (ThreadAbortException e)
            {
                Console.WriteLine("abort thread state:{0}", Thread.CurrentThread.ThreadState.ToString());
                Console.WriteLine("abort message:{0}", e.Message);

　　　　　　//主进程不终止，继续执行
                Thread.ResetAbort();//如果注释此句，线程将执行完finall后中止
            }
            finally
            {
                Console.WriteLine("finally thread state:{0}", Thread.CurrentThread.ThreadState.ToString());
            }
            Console.WriteLine("thread state:{0}", Thread.CurrentThread.ThreadState.ToString());

            Console.ReadLine();
        }
    }
