El hours
valor se agrega al especificado DateTime.The hours
value is added to the specified DateTime. Si hours
es negativo, el resultado DateTime es anterior a la especificada DateTime.If hours
is negative, the resulting DateTime is earlier than the specified DateTime.
La parte del día del resultado DateTime se ve afectada si el tiempo resultante está fuera del día del especificado DateTime.The day part of the resulting DateTime is affected if the resulting time is outside the day of the specified DateTime. La parte del mes del resultado DateTime se ve afectada si el día resultante está fuera del mes del especificado DateTime.The month part of the resulting DateTime is affected if the resulting day is outside the month of the specified DateTime. La parte del año del resultado DateTime se ve afectada si el mes resultante está fuera del año del especificado DateTime.The year part of the resulting DateTime is affected if the resulting month is outside the year of the specified DateTime. La parte de la era del DateTime resultado se ve afectada si el año resultante está fuera de la era DateTimedel especificado.The era part of the resulting DateTime is affected if the resulting year is outside the era of the specified DateTime.
La Kind propiedad del valor devuelto DateTime siempre es igual DateTimeKind.Unspecifieda.The Kind property of the returned DateTime value always equals DateTimeKind.Unspecified. Puede conservar la Kind propiedad time
del parámetro llamando al DateTime.SpecifyKind método, como se muestra en el ejemplo siguiente.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)
