        //首先要说明的是与TopMost的效果不同，TopMost是属性定义，而且设置True后，如果不设为Flase则一直置顶，效果很差，
        //以下方法解决了TopMost使用上的不足
        //调用API
        [System.Runtime.InteropServices.DllImport("user32.dll", CharSet = System.Runtime.InteropServices.CharSet.Auto, ExactSpelling = true)]
        public static extern IntPtr GetForegroundWindow(); //获得本窗体的句柄
        [System.Runtime.InteropServices.DllImport("user32.dll", EntryPoint = "SetForegroundWindow")]
        public static extern bool SetForegroundWindow(IntPtr hWnd);//设置此窗体为活动窗体
                                                                   //定义变量,句柄类型
        public IntPtr Handle1;

        #endregion

        #region ..................窗体加载.............

        private void frmMain_Load(object sender, EventArgs e)
        {
            Handle1= this.Handle;
        }

        #endregion

                FlashWindow(this.Handle, true);//闪烁
                SetForegroundWindow(Handle1);//置顶

闪烁和置顶没有关联性，可单独使用！

另：Handle1 不能改，改成别的名，就不能在最顶层显示。
