本文實例講述了C#實現Winform無邊框移動的方法。分享給大家供大家參考。具體如下：
const int HTLEFT = 10;const int HTRIGHT = 11;const int HTTOP = 12;const int HTTOPLEFT = 13;const int HTTOPRIGHT = 14;const int HTBOTTOM = 15;const int HTBOTTOMLEFT = 0x10;const int HTBOTTOMRIGHT = 17;protected override void WndProc(ref Message m){ switch (m.Msg) { case 0x0084: base.WndProc(ref m); Point vPoint = new Point((int)m.LParam & 0xFFFF, (int)m.LParam >> 16 & 0xFFFF); vPoint = PointToClient(vPoint); if (vPoint.X <= 5) if (vPoint.Y <= 5) m.Result = (IntPtr)HTTOPLEFT; else if (vPoint.Y >= ClientSize.Height - 5) m.Result = (IntPtr)HTBOTTOMLEFT; else m.Result = (IntPtr)HTLEFT; else if (vPoint.X >= ClientSize.Width - 5) if (vPoint.Y <= 5) m.Result = (IntPtr)HTTOPRIGHT; else if (vPoint.Y >= ClientSize.Height - 5) m.Result = (IntPtr)HTBOTTOMRIGHT; else m.Result = (IntPtr)HTRIGHT; else if (vPoint.Y <= 5) m.Result = (IntPtr)HTTOP; else if (vPoint.Y >= ClientSize.Height - 5) m.Result = (IntPtr)HTBOTTOM; break; case 0x0201://鼠標左鍵按下的消息 m.Msg = 0x00A1;//更改消息為非客戶區按下鼠標 m.LParam = IntPtr.Zero;//默認值 m.WParam = new IntPtr(2);//鼠標放在標題欄內 base.WndProc(ref m); break; default: base.WndProc(ref m); break; }}希望本文所述對大家的C#程序設計有所幫助。
