控制台时间

Question

在控制台上同一个位置显示时间倒计时

Answer 1

static void Main(string[] args)
{
    DateTime d = DateTime.Now;
    while ((DateTime.Now - d).TotalSeconds < 10)
    {
        Console.SetCursorPosition(10, 10);
        Console.Write(DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss"));
        Thread.Sleep(1000);
    }
    Console.ReadKey();
}

Answer 2

      int dueInSeconds = 30; 
        DateTime dueTime = DateTime.Now + TimeSpan.FromSeconds(dueInSeconds); 
        int top = Console.CursorTop;
        int left = Console.CursorLeft; 
        System.Threading.ThreadPool.QueueUserWorkItem(delegate(object o) 
        { 
            while (true) 
            { 
                TimeSpan remaining = dueTime - DateTime.Now; 
                if (remaining.TotalSeconds <= 0) return; 
                Console.SetCursorPosition(left, top); 
                Console.Write(string.Format("Remaining seconds: {0,5}", (int)remaining.TotalSeconds)); 
                System.Threading.Thread.Sleep(1000); 
            } 
        }); 
        Console.ReadLine(); 

Answer 3

            int seconds = 100;
            while (seconds > 0)
            {
                Console.SetCursorPosition(0, 0);
                Console.Write("倒计时：{0,3}",seconds);
                seconds--;
                System.Threading.Thread.Sleep(1000);
            }
            Console.ReadKey();
