使用NodaTime計算兩個日期之間的小時數

Question

我正在嘗試使用NodaTime來計算兩個日期之間的小時數，我得到了這個例外：

“單位包含時間單位：小時。參數名稱：單位”

此代碼可以正常工作數年，數月和數天。

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

如果您剛剛獲得日期，最簡單的選擇是將天數乘以24。

或者，創建LocalDateTime值：

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

或者你可以堅持使用LocalDateTime ：

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;
}

這似乎有點無意義 - 為什么多余的時間計算你有幾天的時間？
