每秒输出一个数字
数字在同一个位置
就像倒计时一样
大虾给讲讲

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();




搞定了

呵呵

不错
