移动窗体

在winform中可以拖动窗体移动！

 

bool canMove = true;
private Point mouseOffset; //记录鼠标指针的坐标
private bool isMouseDown = false;

    #region 移动窗体
             
        private void panel1_MouseDown(object sender, MouseEventArgs e)
        {
            int xOffset;
            int yOffset;

            if (e.Button == MouseButtons.Left)
            {
                xOffset = -e.X /*- SystemInformation.FrameBorderSize.Width*/;
                yOffset = -e.Y /*- SystemInformation.CaptionHeight - SystemInformation.FrameBorderSize.Height*/;
                mouseOffset = new Point(xOffset, yOffset);
                isMouseDown = true;
            }
        }

        private void panel1_MouseMove(object sender, MouseEventArgs e)
        {
            if (canMove)
            {
                if (isMouseDown)
                {
                    Point mousePos = Control.MousePosition;
                    mousePos.Offset(mouseOffset.X, mouseOffset.Y);
                    Location = mousePos;
                }
            }
        }

        private void panel1_MouseUp(object sender, MouseEventArgs e)
        {
            // 修改鼠标状态isMouseDown的值
            // 确保只有鼠标左键按下并移动时，才移动窗体
            if (e.Button == MouseButtons.Left)
            {
                isMouseDown = false;
            }
        }
