vs自动生成的代码,我就不再这里重复了。

        Button button1;
        public Form1()
        {
            InitializeComponent();
            this.Text = "我的第一个游戏程序";
            button1 = new Button();
            button1.Location = new Point(25, 25);
            button1.Text = "按钮一";
            //button1.Click += new System.EventHandler(button1_Click);  // 以前的写法,不好理解,
            button1.Click +=button1_Click;  //现在的写法,同样有效,感觉像是借鉴了JavaScript的匿名函数
            this.Controls.Add(button1);
        }

        void button1_Click(object sender, EventArgs e)
        {
            this.button1.Text = "单击了我";
        }
    }
}
