public const Int32 AW_HOR_POSITIVE = 0x00000001;
        public const Int32 AW_HOR_NEGATIVE = 0x00000002;
        public const Int32 AW_VER_POSITIVE = 0x00000004;
        public const Int32 AW_VER_NEGATIVE = 0x00000008;
        public const Int32 AW_CENTER = 0x00000010;
        public const Int32 AW_HIDE = 0x00010000;
        public const Int32 AW_ACTIVATE = 0x00020000;
        public const Int32 AW_SLIDE = 0x00040000;

        [DllImportAttribute("user32.dll")]
        private static extern bool AnimateWindow(IntPtr hwnd, int dwTime, int dwFlags);
  

在關閉事件下寫如下代碼：

  private void FrmLogin_FormClosed(object sender, FormClosedEventArgs e)
        {

                             //表單關閉時表單向上收縮消失！
                           AnimateWindow(this.Handle, 300, AW_SLIDE + AW_VER_NEGATIVE + AW_HIDE);
          
           }
