C# WPF 线程中更改textbox内容

创建线程

	Thread th = new Thread(new ThreadStart(test)); //也可简写为new Thread(ThreadMethod);                
        th.Start(); //启动线程  

线程

	private void test()
        {
            for (; ; Thread.Sleep(1000))
            {
                SetTextCallback d = new SetTextCallback(SetText);   // 托管调用
                this.Dispatcher.Invoke(d, new object[] { "需要写进去的内容" }); 
                
            }
        }

托管调用

        delegate void SetTextCallback(string text); 
        private void SetText(string text)
        {
            textBox1.Text = text;
        }
