創建線程

	Thread th = new Thread(new ThreadStart(test)); //也可簡寫為new Thread(ThreadMethod);                        th.Start(); //啟動線程  
線程
	PRivate void test()        {            for (; ; Thread.Sleep(1000))            {                SetTextCallback d = new SetTextCallback(SetText);   // 托管調用                this.Dispatcher.Invoke(d, new object[] { "需要寫進去的內容" });                             }        }
托管調用
        delegate void SetTextCallback(string text);         private void SetText(string text)        {            textBox1.Text = text;        }
