在图标的MouseMove事件中加入，用来确定图标位置信息

        GetIconInfo();<pre name="code" class="csharp">        //获取图标位置信息private void GetIconInfo(){Point p = Cursor.Position;MyIcon.hWnd = WindowFromPoint(p);int BtnSize = SendMessage(MyIcon.hWnd, TB_GETBUTTONSIZE, IntPtr.Zero, IntPtr.Zero);MyIcon.Width = BtnSize & 0xFFFF;MyIcon.Height = (BtnSize / 0x10000) & 0xFFFF;Rect rect = new Rect();if (GetWindowRect(MyIcon.hWnd, out rect)){if (MyIcon.Width != 0 && MyIcon.Height != 0){MyIcon.X = (p.X - rect.Left - py) / MyIcon.Width * MyIcon.Width + rect.Left + py;MyIcon.Y = (p.Y - rect.Top - py) / MyIcon.Height * MyIcon.Height + rect.Top + py;}}}
