HijriCalendar.AddYears Method (DateTime, Int32)
Assembly: mscorlib (in mscorlib.dll)
The number of years to add.
The day part of the resulting DateTime is affected if the resulting day is not a valid day in the resulting month of the resulting year. It is changed to the last valid day in the resulting month of the resulting year. The month part of the resulting DateTime remains the same as the specified DateTime. This implementation supports only the current era. Therefore, ArgumentException is thrown if the resulting year is outside the era of the specified DateTime. The time-of-day part of the resulting DateTime remains the same as the specified DateTime.
For example, Zulhijjah has 29 days, except during leap years when it has 30 days. If the specified date is the 30th day of Zulhijjah in a leap year and the value of years is 1, the resulting date will be the 29th day of Zulhijjah in the following year.
TheKind property of the returned DateTime value always equals DateTimeKind.Unspecified. You can preserve the Kind property of the time parameter by calling the DateTime.SpecifyKind method, as the following example shows.
