在控制台，做一个元旦倒计时

[hanzhaoever]

用timer

[cuike519]

            DateTime newYear = new DateTime(2009, 12, 31, 23, 59, 59);

            TimeSpan sub = newYear.Subtract(DateTime.Now);
            while (sub > new TimeSpan(0)) {
                Console.WriteLine("距离元旦还有：" + sub.Hours + "小时");
            }

楼上已结

[Shift2010]

DateTime newYear = new DateTime(2009, 12, 31, 23, 59, 59);

TimeSpan sub = newYear.Subtract(DateTime.Now);
while (sub > new TimeSpan(0)) {
Console.WriteLine("距离元旦还有：" + sub.Hours + "小时");
}

[Shift2010]

time_t t = time(0);
char tmp[64];
strftime( tmp, sizeof(tmp), "%Y/%m/%d %X %A 本年第%j天 %z",localtime(&t) );
puts( tmp );
return 0;

C# code DateTime newYear=new DateTime(2009,12,31,23,59,59);

TimeSpan sub= newYear.Subtract(DateTime.Now);while (sub>new TimeSpan(0)) {
Console.WriteLine("距离元旦还有?-

偶新手，麻烦能说明哈：
为什么是个死循环；
有注释最好！谢谢。

三楼的是死循环....

3楼的代码有严重的逻辑错误，输出控制也不好...改成如下...

DateTime newYear = new DateTime(2010, 1, 1);
TimeSpan sub = newYear.Subtract(DateTime.Now);
while (sub.Ticks > 0)
{
    sub = newYear.Subtract(DateTime.Now);
    Console.Clear();
    Console.Write("距离元旦还有：{0}天{1}小时{2}分{3}秒", sub.Days, sub.Hours, sub.Minutes, sub.Seconds);
    Thread.Sleep(1000);
}

楼上代码很简洁实用~

[xuedonglei0396]

刚来，跟高手学习一下

[Shift2010]

领教了

[kensouterry]

自己计算 2010.1.1离 DateTime.Now的时间差，然后将数据表示出来。
