建立後臺執行緒重新整理UI：

        //建立代理
        private delegate void DelegateRefreshUI();

        //真正執行重新整理UI的函式
        private void freshUI()
        {
            //重新整理UI
        }

        //重新整理UI函式
        private void RefreshUI()
        {
            //每隔5秒重新整理UI
            while(true)
            {
                Thread.Sleep(5000);
                Dispatcher.Invoke(DispatcherPriority.Normal,new DelegateRefreshUI(freshUI));
            }
        }

        //建立後臺重新整理UI執行緒
        Thread t = new Thread(new ThreadStart(RefreshUI));
        t.IsBackground = true;
        t.Start();
 

    多執行緒中實時重新整理UI：

        //建立代理
        public delegate void delegateSetLabelTxt(string strTxt);
        public delegateSetLabelTxt setLabelTxt;

        //設定Label的text
        private void SetTxt(string strTxt)
        {
            if(this.label1.InvokeRequired)
            {
                this.setLabelTxt += new delegateSetLabelTxt(SetTxt);
                this.Invoke(setLabelTxt, new object[] { strTxt });
            }
            else
            {
                this.label1.Text = strTxt;
            }
        }
