一个可移动的无Border父窗体类

在Winform编程中可能我们会觉得windows自己的窗体样式有点丑，想要好看一些的，可是我们将窗体边框隐藏之后又发现窗体没办法移动，这时我们就需要自己做一些操作，让鼠标不管点着窗体什么地方都可以移动窗体。

我的做法时做一个父窗体，其他需要无边框可移动的窗体都继承它，请看代码

    /// <summary>
    /// 一个可移动窗体无Border父窗体类
    /// 
    /// </summary>
    public partial class FormParent : Form
    {
        public FormParent()
        {
            InitializeComponent();
        }

        //鼠标拖动变量
        protected bool isMouseDown = false;
        protected Point FormLocation;
        protected Point mouseOffset;



        //鼠标按下时记录窗体位置
        protected void FormParent_MouseDown(object sender, MouseEventArgs e)
        {
            if (e.Button == MouseButtons.Left)
            {
                isMouseDown = true;
                FormLocation = this.Location;
                mouseOffset = Control.MousePosition;

            }
        }

        //鼠标移动时改变窗体位置
        protected void FormParent_MouseMove(object sender, MouseEventArgs e)
        {
            int x = 0;
            int y = 0;
            if (isMouseDown)
            {
                Point pt = Control.MousePosition;
                x = mouseOffset.X - pt.X;
                y = mouseOffset.Y - pt.Y;
                this.Location = new Point(FormLocation.X - x, FormLocation.Y - y);
            }
        }

        //鼠标松开后释放窗体跟随
        protected void FormParent_MouseUp(object sender, MouseEventArgs e)
        {
            isMouseDown = false;
        }

        private void pictureBox1_Click(object sender, EventArgs e)
        {
            this.Close();
        }
    }
