Question

我试图使用NodaTime来计算两个日期之间的小时数，我得到了这个例外：

＆＃34;单位包含时间单位：小时。参数名称：units＆＃34;

此代码可以正常使用数年，数月和数天。

public ElapsedTimeNodaTime(DateTime StartDate, DateTime EndDate)
{
   var birthday = new LocalDate(StartDate.Year, StartDate.Month, Date.Day);
   var today = new LocalDate(EndDate.Year, EndDate.Month, EndDate.Day);

    Years = Period.Between(birthday, today, PeriodUnits.Years).Years;
    Months = Period.Between(birthday, today, PeriodUnits.Months).Months;
    Days = Period.Between(birthday, today, PeriodUnits.Days).Days;
    Hours = Period.Between(birthday, today, PeriodUnits.Hours).Hours;
}

Answer 1

如果您有日期，最简单的选择是将天数乘以24。

或者，改为创建LocalDateTime值：

Hours = Period.Between(birthday.AtMidnight(), today.AtMidnight(), PeriodUnits.Hours).Hours;

或者你可以坚持LocalDateTime所有事情：

public ElapsedTimeNodaTime(DateTime startDate, DateTime endDate)
{
   var birthday = startDate.ToLocalDateTime();
   var today = endDate.ToLocalDateTime();

    Years = Period.Between(birthday, today, PeriodUnits.Years).Years;
    Months = Period.Between(birthday, today, PeriodUnits.Months).Months;
    Days = Period.Between(birthday, today, PeriodUnits.Days).Days;
    Hours = Period.Between(birthday, today, PeriodUnits.Hours).Hours;
}

虽然看起来有点无意义 - 为什么要多余地计算你有几天的时间？
