委托事件 简写与原来写法 (临时函数)转

 public MainPage()
        {
            this.InitializeComponent();

            //简写
            this.Loaded += (sender, e) => { MessageBox.Show("d"); MessageBox.Show("ss"); };
            //原来写法
            this.Loaded +=new RoutedEventHandler(MainPage_Loaded);
        }

        void MainPage_Loaded(object sender, RoutedEventArgs e)
        {
            //简写
            this.Dispatcher.BeginInvoke(() => MessageBox.Show("dd"));
            //原来写法
            this.Dispatcher.BeginInvoke(test);
        }

        void test()
        {
            MessageBox.Show("dd");
        }
