설명

hours 값이 추가 되는 지정 된 DateTime합니다.The hours value is added to the specified DateTime. 하는 경우 hours 음수인 경우 결과 DateTime 지정 된 이전의 DateTime합니다.If hours is negative, the resulting DateTime is earlier than the specified DateTime.

결과의 일 부분 DateTime 결과 지정 된 날짜 범위를 벗어나는 경우 영향을 받는 DateTime합니다.The day part of the resulting DateTime is affected if the resulting time is outside the day of the specified DateTime. 결과의 월 부분 DateTime 결과 일 월을 지정 된 범위를 벗어나는 경우 영향을 받는 DateTime합니다.The month part of the resulting DateTime is affected if the resulting day is outside the month of the specified DateTime. 결과의 연도 부분 DateTime 월의 지정 된 연도 범위를 벗어나는 경우 영향을 받는 DateTime합니다.The year part of the resulting DateTime is affected if the resulting month is outside the year of the specified DateTime. 결과의 연대 부분이 DateTime 지정 된 연대를 벗어나는 결과 연도 DateTime합니다.The era part of the resulting DateTime is affected if the resulting year is outside the era of the specified DateTime.

합니다 Kind 반환 된 속성 DateTime 값이 항상 DateTimeKind.Unspecified합니다.The Kind property of the returned DateTime value always equals DateTimeKind.Unspecified. 유지할 수 있습니다는 Kind 의 속성을 time 호출 하 여 매개 변수는 DateTime.SpecifyKind 메서드를 다음 예제와 같이 합니다.You can preserve the Kind property of the time parameter by calling the DateTime.SpecifyKind method, as the following example shows.

returnTime = DateTime.SpecifyKind(cal.AddHours(time, hours), time.Kind);
returnTime = DateTime.SpecifyKind(cal.AddHours(time, hours), time.Kind)
