lambda表达式的出现基本上取代了delegate操做符的使用this

  public MainWindow()
        {
            InitializeComponent();
            this.button1.Click += button1_Click;
        }

        void button1_Click(object sender, RoutedEventArgs e)
        {
            this.textbox1.Text = "hello world";
        }

使用delegate转变为匿名方法spa

 public MainWindow()
        {
            InitializeComponent();
            this.button1.Click += delegate(object sender, RoutedEventArgs e)
            {
                this.textbox1.Text = "hello world";
            };
        }

使用lambda表达式转变为code

  public MainWindow()
        {
            InitializeComponent();
            this.button1.Click += ( sender,  e)=>
            {
                this.textbox1.Text = "hello world";
            };
        }
