Winform 多线程问题

Question

早上写了一个线程，可以实现每隔1秒，在Label上动态更新数据的功能。具体代码如下：
 //定义线程
        private Thread threadProd;
        //private Thread threadGetProd;         //定义委托
        delegate void set_Text(string s);
        set_Text setText;        delegate void set_Time(string s);
        set_Time setTime;        //定义计数器
       // private static int Count = 0;        public ThreadForm()
        {
            InitializeComponent();
        }        private void ThreadForm_Load(object sender, EventArgs e)
        {
            //委托实例化
            setText = new set_Text(set_LabelText);
            setTime = new set_Time(set_LabelTime);
        }        private void set_LabelText(string s)//主程序调用的函数
        {
            lblCount.Text = s;//测试数据
        }        private void set_LabelTime(string s)
        {
            lblTime.Text = s;//测试时间
        }        public void run()
        {
            for (int i = 0; i < 86400; i++)
            {
                VerifyCode verifyCode = new VerifyCode();
                lblCount.Invoke(setText, new object[] { verifyCode.CreateVerifyCode() });
                lblTime.Invoke(setTime, new object[] { DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss.fff") });
                Thread.Sleep(1000);
            }
        }        private void ThreadForm_FormClosing(object sender, FormClosingEventArgs e)
        {
            if (threadProd.IsAlive)//判断线程是否存在
            {
                threadProd.Abort();//撤销线程
            }
        }        private void btnClick_Click(object sender, EventArgs e)
        {
            threadProd = new Thread(new ThreadStart(run));
            threadProd.Start();
        }
上面的线程就是不停的产生新数据，但是，我现在想再写一个线程 用于获取1分钟内Label变化的值。假如说1分钟60个，就是把这60个值显示出来,每分钟显示一次。

Answer 1

定时的操作不要用Thread.Sleep，这不是正常的使用方式，就好像用西瓜刀去切猪肉一样，能不能切？能，但是很容易切到手哦。还有，如果不是必要，少开线程。不是说线程用的多就牛逼，而是合理。

Answer 2

一开始用的timer控件，马马虎虎可以实现功能，现在改成线程，遇见困难了，等待高手指点。
