C#.NET跨线程调用控件

//定义线程和线程操作方法的委托
        private delegate void FlushClient();
        private Thread _trStop;

//开启线程

        _trClose = new Thread(WinClose);

         _trClose.Start();

//线程对应的方法

        private void WinClose()
        {
            Thread.Sleep(8 * 1000);
            while (true)
            {
                Thread.Sleep(1 * 100);
                ThreadFunction();
            }
        }

//方法操作的内容。InvokeRequired和Invoke
        private void ThreadFunction()
        {
            if (panel1.InvokeRequired)
            {
                FlushClient fc = new FlushClient(ThreadFunction);
                Invoke(fc);
            }
            else
            {
                _opacity -= 0.05;
                Opacity = _opacity;
                if (_opacity < 0.1)
                {
                    WinApi.AnimateWindow(Handle, 500, WinApi.AW_SLIDE | WinApi.AW_VER_POSITIVE | WinApi.AW_HIDE);
                    Hide();
                    _trClose.Abort();
                }
            }
        }
