C# 60 秒倒计时怎么写

sleep(60000);配合一个timer进行显示

直接用Timer控件可以实现，在timer函数中可以设置一个变量来启动代码，可以把timer设为100毫秒，然后经过累加到60秒后触发别的事件

int i = 60;
private void button2_Click(object sender, EventArgs e)
{
    timer1.Interval = 1000;
    timer1.Start();}private void timer1_Tick(object sender, EventArgs e)
{
    textBox1.Text = i.ToString();
    if (i == 0) timer1.Stop();
    else i--;
}

private DateTime endTime;
void Form1_Load(object sender, EventArgs e)
{
endTime= DateTime.Now.AddMinutes(1);
timer1.Enabled = true;
}
private void timer1_Tick(object sender, EventArgs e)
{
DateTime show = endTime.Subtract(new TimeSpan(DateTime.Now.Ticks));
label1.Text = show.ToLongTimeString();
}

我的一个简单的用Timer控件的小例子，楼主可以参考一下private void button1_Click(object sender, EventArgs e)
{
   timer1.Enabled = true;
}int time =60;
private void timer1_Tick(object sender, EventArgs e)
{
   this.button1.Text = "请耐心等候(" + time.ToString() + "秒)";
   time = time - 1;
   if (time < 0)
    {
        this.Close();
        this.timer1.Enabled = false;
     }
}

        private void btnBegin_Click(object sender, EventArgs e) {
            Thread counter = new Thread(Counter);
            counter.Start();        }
        int i = 60;
        public void Counter() {
            while (i > 1) {
                i--;
                Console.WriteLine("倒计时:{0}秒", i.ToString());
                Thread.Sleep(1000);
            }        }

        /// <summary>
        /// 倒计时器
        /// </summary>
        /// <param name="seconds">秒</param>
        public void Counter(int seconds) {            if (seconds > 0) {
                Thread.Sleep(1000);
                Console.WriteLine("倒计时:{0}秒", seconds.ToString());
            }
            seconds--;
            Counter(seconds);
        }

我的这个例子再补充一下，把控件timer1的属性Interval设置成1000毫秒，也就是1秒，这个属性是控制Elapsed事件的频率的

用javascript實現，以下是代碼：
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
    <title>未命名頁面</title>    <script language="javascript">
      var i = 3
     function onload()
     {
         var time = document.getElementById('time');
         i--;
        time.innerHTML = i+'秒';
        setTimeout("onload()",1100);
       if(i==0)
       {
           window.location.href('../newmenu/homec.asp?msg_flag=1');
        }
    }    </script></head>
<body onload="onload()">
    <form id="form1" runat="server">
        <div>
            <table id="Table3" align="center" border="0" cellpadding="0" cellspacing="0" style="width: 780px;
                height: 306px">
                <tr>
                    <td align="center">
                        <span style="font-size: 14pt; color: #0000ff; font-family: SimSun"><span style="color: #ff0033">
                            已無數據可以進行提交!<br />
                        </span>
                            <br />
                            <span id="time"> </span>內將返回首頁!</span></td>
                </tr>
            </table>
        </div>
    </form>
</body>
</html>

  static void Main(string[] args)
        {
                      DateTime dt = DateTime.Now;
            while (true)
            {
                DateTime dt2 = DateTime.Now;
                TimeSpan ts = dt2 - dt;
                if (ts.Seconds <= 60)
                {
                    Console.Clear();
                    Console.Write(60 - ts.Seconds);
                    Thread.Sleep(100);
                }
                else
                {
                    break;
                }
            }
           // Console.Read();
        }
