c# winform 让lable的值不断变化，可不可以不用时间控件?

C# code

 for(int i=0;i<10;i++)            {                this.label1.Text = i.ToString();            }  

C# code

        private delegate void SetLabelDelegate(DateTime dt);        private void button2_Click(object sender, EventArgs e)        {            Thread th = new Thread(ShowCurrentTime);            th.Start();        }        private void ShowCurrentTime()        {            while (true)            {                SetLabelValue(DateTime.Now);                Thread.Sleep(1000);            }        }        private void SetLabelValue(DateTime dt)        {            if (this.InvokeRequired)            {                this.Invoke(new SetLabelDelegate(SetLabelValue), new object[] { dt });            }            else            {                this.label1.Text = dt.ToString();            }        }
