# 加一天tomorrow=today+datetime.timedelta(days=1)# 减一天yesterday=today-datetime.timedelta(days=1)# 加一个小时next_hour=now+datetime.timedelta(hours=1)# 减一个小时prev_hour=now-datetime.timedelta(hours=1)print('明天:',tomorrow)print('昨天:',yesterday)print('下一个小时:',next_hour)print('...
DateTime now = DateTime.Now; DateTime nextSecond = now.add(TimeSpan.FromSeconds(1)); 这个例子中,我们使用TimeSpan.FromSeconds()方法创建一个表示一秒的时间间隔,并将其添加到当前日期和时间上,得到下一秒的日期和时间。 DateTime.add()方法在许多应用场景中都非常有用,例如计算未来的日期和时间、计算...
