C# WPF 使用委托修改UI控件

近段时间在自学WPF，是一个完全不懂WPF的菜鸟，对于在线程中修改UI控件使用委托做一个记录，给自已以后查询也给需要的参考：

界面只放一个RichTextBox，在窗体启动时开起两个线程，调用两个函数，每隔1秒写一次当前时间

一界面XAML如下：

<Window x:Class="WpfApplication1.MainWindow"

        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

        Title="MainWindow" Height="" Width="" WindowStartupLocation="CenterScreen" Loaded="Window_Loaded">

    <Grid>

        <ScrollViewer>

            <RichTextBox HorizontalAlignment="Stretch" Margin="" Name="richTextBox1" VerticalAlignment="Stretch" />

        </ScrollViewer>

    </Grid>

</Window>

二在界面启动时开启两个线程：

         private void Window_Loaded(object sender, RoutedEventArgs e)

         {

             //创建线程1

             Thread t1 = new Thread(new ThreadStart(T1));

             t1.Start();

             //创建线程2

             Thread t2 = new Thread(new ThreadStart(T2));

             t2.Start();

         }

三线程调用函数：

        /// <summary>

        /// 线程1调用函数

        /// add by

        /// </summary>

        private void T1()

        {

            while (true)

            {

                Thread.Sleep(TimeSpan.FromSeconds());

                ShowMsg(string.Format("T1 {0}", System.DateTime.Now.ToString("yyyy-MM-dd hh:mm:ss:fff")));

            }

        }

        /// <summary>

        /// 线程2调用函数

        /// add by

        /// </summary>

        private void T2()

        {

            while (true)

            {

                Thread.Sleep(TimeSpan.FromSeconds());

                ShowMsg(string.Format("T2 {0}", System.DateTime.Now.ToString("yyyy-MM-dd hh:mm:ss:fff")));

            }

        }

三写前端函数：

        private void ShowMsg(string sMsg)

        {

            this.Dispatcher.BeginInvoke(DispatcherPriority.Normal, (ThreadStart)delegate() {

                richTextBox1.AppendText(string.Format("{0} \r\n",sMsg));

            });

        }
