WinForm控件拖拽类

前言：卖麻辣烫归来后实在太累，写代码来消遣，最近搞Winform，感觉标题栏太丑，就想拖拽窗体，自己写了个拖拽控件类，方便自己使用，没啥技术含量，就是想瞎写写，明天打印出来贴在店里，没事盯着，缅怀我逝去的程序员生涯。
public class DragControl { private Control _drag = null; private Control _move = null; private Cursor _oldCursor = null; private int initialX; private int initialY; private DragControl() { } public DragControl(Control drag,Control move) { _drag = drag; _move = move; } public DragControl(Control dragControl) : this(dragControl, dragControl) { } public void CloseDrag() { _drag.Cursor = _oldCursor; _drag.MouseDown -= MoveTipDown; } public void OpenDrag() { _oldCursor = _drag.Cursor; _drag.Cursor = Cursors.SizeAll; _drag.MouseDown += MoveTipDown; } private void MoveTipDown(object sender, MouseEventArgs e) { initialX = e.X; initialY = e.Y; _drag.MouseMove += MoveTipMove; _drag.MouseUp += MoveTipUp; } private void MoveTipUp(object sender, MouseEventArgs e) { _drag.MouseMove -= MoveTipMove; _drag.MouseUp -= MoveTipUp; } private void MoveTipMove(object sender, MouseEventArgs e) { if (e.Y != initialY) _move.Top = _move.Top + (e.Y - initialY); if (e.X != initialX) _move.Left = _move.Left + (e.X - initialX); } }
