看C#源码笔记

笔记1

退出程序的方法用这个：

        private void button3_Click(object sender, EventArgs e)        {            Application.Exit();        }

使用组件拖动窗体

private int startX, startY;        private void button1_MouseDown(object sender, MouseEventArgs e)        {            if (e.Button == MouseButtons.Left)            {                startX = e.X;                startY = e.Y;            }        }        private void button1_MouseMove(object sender, MouseEventArgs e)        {            if (e.Button == MouseButtons.Left)            {                this.Left += e.X - startX;                this.Top += e.Y - startY;            }        }
