C# 无边框窗体的移动

无边框窗体的移动：

bool formMove = false;//窗体是否移动
        Point formPoint;//记录窗体的位置

        private void AddFriendForm2_MouseDown(object sender, MouseEventArgs e)
        {
            formPoint = new Point();
            int xOffset;
            int yOffset;
            if (e.Button == MouseButtons.Left)
            {
                xOffset = -e.X - SystemInformation.FrameBorderSize.Width;
                yOffset = -e.Y - SystemInformation.CaptionHeight - SystemInformation.FrameBorderSize.Height;
                formPoint = new Point(xOffset, yOffset);
                formMove = true;//开始移动
            }
        }

        private void AddFriendForm2_MouseMove(object sender, MouseEventArgs e)
        {
            if (formMove == true)
            {
                Point mousePos = Control.MousePosition;
                mousePos.Offset(formPoint.X, formPoint.Y);
                Location = mousePos;
            }
        }

        private void AddFriendForm2_MouseUp(object sender, MouseEventArgs e)
        {
            if (e.Button == MouseButtons.Left)//按下的是鼠标左键
            {
                formMove = false;//停止移动
            }
        }

 

最大化最小化那些其实都是自己加的，可以用image点击事件里面实现最大化最小化以及关闭

我用的是label：

 private void label1_Click(object sender, EventArgs e)
        {
            this.WindowState = FormWindowState.Minimized;
        }

        private void label2_Click(object sender, EventArgs e)
        {
            this.Close();
        }
