winform技巧—没有边框移动窗体的方法

        #region 可移动

        [DllImport("user32.dll")]

        public static extern bool ReleaseCapture();

        [DllImport("user32.dll")]

        public static extern bool SendMessage(IntPtr hwnd, int wMsg, int wParam, int lParam);

        public const int WM_SYSCOMMAND = 0x0112;

        public const int SC_MOVE = 0xF010;

        public const int HTCAPTION = 0x0002;

        //在窗体的MouseDown事件里加上代码

        private void FrmCheer_MouseDown(object sender, MouseEventArgs e)

        {

            ReleaseCapture();

            SendMessage(this.Handle, WM_SYSCOMMAND, SC_MOVE + HTCAPTION, 0);

        }
