关于线程的参数（2.0）、“返回值”、及线程的中止

1.线程的参数：
有时候会想向辅助线程传递些信息，这里需要用到ParameterizedThreadStart 委托

示例：

        private void btRunThread_Click(object sender, EventArgs e)

        {

            Thread t = new Thread(new ParameterizedThreadStart(this.ThreadRun));

            t.Start(100);

        }

        private void ThreadRun(object o)

        {

            this.lbCompleted.Invoke((MethodInvoker)delegate { this.lbCompleted.Text = System.Convert.ToString(o); });

        }

2.通过代理可以大致实现类似功能，示例：

    class Program

    {

        static void Main(string[] args)

        {

            ThreadClass tc = new ThreadClass(new MyDlg(DlgMethod));

            Thread thread = new Thread(new ThreadStart(tc.ThreadRun));

            Console.WriteLine("second thread start");

            thread.Start();

            thread.Join();

            Console.WriteLine("second thread completed");

            Console.Read();       

        }

        private static void DlgMethod(int i)

        {

            Console.WriteLine("Second Thread Result:{0}", i);

        }

    }

    public delegate void MyDlg(int i);

    class ThreadClass

    {

        private MyDlg myDlg;

        public ThreadClass(MyDlg pDlg)

        {

            this.myDlg = pDlg;

        }

        public void ThreadRun()

        {

            int total = 0;

            for (int i = 0; i < 100; i++)[next]

            {

                total += i;

            }

            if (myDlg != null)

            {

                myDlg(total);

            }

        }
