C#winform界面中如何显示当前时间，是用lable控件实现

private void Form1_Load(object sender, EventArgs e)

        {

            Thread t = new Thread(delegate()

                {

                    while (true)

                    {

                        Invoke(new EventHandler( delegate

                        {

                            label1.Text = DateTime.Now.ToLongTimeString();

                        }));

                        Thread.Sleep(500);

                    }

                });

            t.IsBackground = false;

            t.Start();

        }

放在load事件中，自己添加一个label1，就可以了。
