给你贴出后台代码

 

给噶个实例！

  public partial class Form1 : Form
    {
        private static bool stopStatus = false;
        private static int finishTime = 0;
        private static int numIndex = 0;
        private static string passNum = string.Empty;
        public Form1()
        {
            InitializeComponent();
            CheckForIllegalCrossThreadCalls = false;
        }
        private void btnBegin_Click(object sender, EventArgs e)
        {
            stopStatus = false;
            Thread changeTimeThread = new Thread(ChangeTime);
            changeTimeThread.IsBackground = true;
            changeTimeThread.Start();
        }
        private void ChangeTime()
        {
            while (!stopStatus)
            {
                string hasFinishedTime = "";
                if (finishTime / 60 >= 10)
                {
                    hasFinishedTime = (finishTime / 60).ToString();
                }
                else
                {
                    hasFinishedTime = "0" + finishTime / 60;
                }
                hasFinishedTime += ":";
                int secondTime = finishTime - (finishTime / 60) * 60;
                if (secondTime / 10 >= 1)
                {
                    hasFinishedTime += secondTime;
                }
                else
                {
                    hasFinishedTime += "0" + secondTime;
                }
                finishTime++;
                this.time.Text = "时间已过:" + hasFinishedTime;
                Thread.Sleep(1000);
            }
 
        }
        private void btnStop_Click(object sender, EventArgs e)
        {
                stopStatus = true;
                btnBegin.Enabled = true;
                btnNext.Enabled = false;
                           
    }

 前台控件自己定义就可以了！
