分不多了，求一个时间段算法
是一个停车场的算法，有一种停车卡：早7:00~23:00免费，其他时间2元一小时，每超过15分钟算一小时整。总停车费为all_fee,开始时间为start_time，离开时间为end_time。求这个算法。。。

if (DateTime.Now.Hour > 7 && DateTime.Now.Hour < 23)
stopCar.CarState = StopCarInfo.State.Free;
[解决办法]
你都没有看这两部内容呀
int parkDay = (int)((endTime - startTime) / 24);//每超过24小时意味着要收费8小时
+ parkDay * 8
[解决办法]
private void Timer_Elapsed(object sender, EventArgs e)
{
//收费时间段
if (DateTime.Now.Hour < 7 && DateTime.Now.Hour > 23)
{
foreach (var car in CarList)
{
if (car.CarState == StopCarInfo.State.Free)
{
car.CarState = StopCarInfo.State.In;
}
// 离开停车场
if (car.CarState == StopCarInfo.State.Out)
{
var hh = (car.PassTime - car.StopTime).Seconds;
var mm = (car.PassTime - car.StopTime).Milliseconds;
if (hh > 1)
{
car.All_Fee = hh * 2;
}
if (mm > 15)
{
car.All_Fee += 2;
}
// 停车费用
System.Console.WriteLine(car.All_Fee);
// 收费完成
car.CarState = StopCarInfo.State.Finish;
}
//收费的经过时间
car.PassTime = car.PassTime.AddSeconds(1);
}
}
}
[解决办法]
var hh = (car.PassTime - car.StopTime).Hours;
var mm = (car.PassTime - car.StopTime).Minutes;
