WPF 多线程与委托

public MainWindow()
        {
            InitializeComponent();
            GetData();
            _mydele = new MyDelegate(SetValue);
        }
        delegate void MyDelegate(string msg);
        MyDelegate _mydele;
        Thread t;
        private void button1_Click(object sender, RoutedEventArgs e)
        {
            //MessageBoxResult key = MessageBox.Show("确定退出？", "温馨提示", MessageBoxButton.YesNo, MessageBoxImage.Question, MessageBoxResult.No);
            //if (MessageBox.Show("确定退出？", "温馨提示", MessageBoxButton.YesNo, MessageBoxImage.Question, MessageBoxResult.No) == MessageBoxResult.Yes)
            //{
            //    MessageBox.Show("点了yes");
            //}
            t = new Thread(new ThreadStart(Run));
            t.Start();
        }

        private void Run()
        {
            while (true)
            {
                string msg = DateTime.Now.ToString() + " " + DateTime.Now.Millisecond.ToString();
                
                this.Dispatcher.Invoke(_mydele, new object[] { msg });
                Thread.Sleep(1000);
            }
        }
        
        private void SetValue(string msg)
        {
            this.lbl.Content = msg;
        }

在WPF中Window类并没有Invoke方法,但是WPF提供了专门负责线程调度工作的Window.Dispatcher类,每个线程都有一个,我们在一个线程中要让另一个线程做事情,其实就是调用目标Dispatcher调度完成.
