C# 如何在空间运行时调整控件位置和大小

最近需要实现这个功能，结合网上搜索代码，实现了该功能。

 

代码如下：

 

private void L*****_MouseMove(object sender, MouseEventArgs e)
        {
            //((Control)sender).Cursor = Cursors.Hand;
            //bChangeSizeMode = false;
            if (!bMouseDown)
            {
                int right = ((Control)sender).Width;
                int bottom = ((Control)sender).Height;
                if (e.X > (right - 10) && e.Y > (bottom - 10))
                {
                    ((Control)sender).Cursor = Cursors.SizeNWSE;
                    bChangeSizeMode = true;
                }
                else if (e.X > (right - 10))
                {
                    ((Control)sender).Cursor = Cursors.VSplit;
                    bChangeSizeMode = true;
                }
                else if (e.Y > (bottom - 10))
                {
                    ((Control)sender).Cursor = Cursors.HSplit;
                    bChangeSizeMode = true;
                }
                else
                {
                    ((Control)sender).Cursor = Cursors.SizeAll;
                    bChangeSizeMode = false;
                }
            }

            if (bMouseDown && bMoveMode)
            {
                if (bChangeSizeMode)
                {
                    if (e.Button == MouseButtons.Left)
                    {
                        if (((Control)sender).Cursor == Cursors.VSplit)
                        {
                            ((Control)sender).Width = e.X;
                        }
                        else if (((Control)sender).Cursor == Cursors.HSplit)
                        {
                            ((Control)sender).Height = e.Y;
                        }
                        else
                        {
                            ((Control)sender).Width = e.X;
                            ((Control)sender).Height = e.Y;
                        }
                        ((Control)sender).Tag = ((Control)sender).Width + ":" + ((Control)sender).Height + ":" + ((Control)sender).Left + ":" + ((Control)sender).Top + ":" + ((Control)sender).Font.Size;
                    }
                    bLocationChanged = true;
                }
                else 
                {
                    //((Control)sender).Cursor = Cursors.Hand;//设置拖动时鼠标箭头
                    if (e.Button == MouseButtons.Left)
                    {
                        Point mousePos = Control.MousePosition;
                        mousePos.Offset(mouseOffset.X, mouseOffset.Y);//设置偏移
                        ((Control)sender).Location = ((Control)sender).Parent.PointToClient(mousePos);
                        ((Control)sender).Tag = ((Control)sender).Width + ":" + ((Control)sender).Height + ":" + ((Control)sender).Left + ":" + ((Control)sender).Top + ":" + ((Control)sender).Font.Size;
                    }
                    bLocationChanged = true;
                }
            }
        }
