无框窗体移动

为什么80%的码农都做不了架构师？>>>   

在窗体中定义两个变量

Point mouseOff;//鼠标移动位置变量
 bool leftFlag;//标签是否为左键

窗体的三个鼠标事件

this.MouseMove += new MouseEventHandler(MainWindow_MouseMove);

            this.MouseDown += new MouseEventHandler(MainWindow_MouseDown);

            this.MouseUp += new MouseEventHandler(LoginForm_MouseUp);

事件代码：

private void MainWindow_MouseDown(object sender, MouseEventArgs e)
        {
            if (e.Button == MouseButtons.Left)
            {
                mouseOff = new Point(-e.X, -e.Y); //得到变量的值
                leftFlag = true;                  //点击左键按下时标注为true;
            }
        }

        private void MainWindow_MouseMove(object sender, MouseEventArgs e)
        {
            if (leftFlag)
            {
                Point mouseSet = Control.MousePosition;
                mouseSet.Offset(mouseOff.X, mouseOff.Y);  //设置移动后的位置
                Location = mouseSet;

            }
        }

        private void LoginForm_MouseUp(object sender, MouseEventArgs e)
        {
            if (leftFlag)
            {
                leftFlag = false;//释放鼠标后标注为false;
            }
        }

有了这三个事件就能支持无边框窗体移动了
