写写

WPF使用多线程访问控件及打开新窗口：

private void button1_Click(object sender, RoutedEventArgs e)
        {
            Thread thread = new Thread(new ParameterizedThreadStart(AppendData));
            thread.SetApartmentState(ApartmentState.STA);//由新线程去开启新窗口时需要设置
            thread.IsBackground = true;
            thread.Start("ABC");
        }

        delegate void AppendText(string message);
        void AppendData(object msge)
        {
            Dispatcher.BeginInvoke(new AppendText(app), new object[] { msge.ToString() });//访问控件
            Th t = new Th();
            t.Show();
            System.Windows.Threading.Dispatcher.Run();//开启新窗口后要是没有加上这句，打开的窗口会很快被关闭掉

           
        }

      //控件赋值
        void app(string msg)
        {
            txtbox.Text = msg;
        }

WPF实现与winform的timer控件功能

使用

DispatcherTimer 类

DispatcherTimer timer = null;
        public MainWindow()
        {
            InitializeComponent();
            timer = new DispatcherTimer();
            timer.Tick += new EventHandler(timer_Tick);
            timer.Interval = TimeSpan.FromSeconds(1);
            timer.Start();
        }

        private void button1_Click(object sender, RoutedEventArgs e)
        {
            timer.Stop();//停止
        }
