Comentários
A parte do dia do resultado DateTime será afetada se o dia resultante não for um dia válido no mês resultante do ano resultante.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. Ele é alterado para o último dia válido no mês resultante do ano resultante.It is changed to the last valid day in the resulting month of the resulting year. A parte do mês do resultado DateTime permanece a mesma que a especificada DateTime .The month part of the resulting DateTime remains the same as the specified DateTime. Essa implementação dá suporte apenas à era atual.This implementation supports only the current era. Portanto, ArgumentException será gerado se o ano resultante estiver fora da era do especificado DateTime .Therefore, ArgumentException is thrown if the resulting year is outside the era of the specified DateTime. A parte de hora do dia do resultado DateTime permanece a mesma que a especificada DateTime .The time-of-day part of the resulting DateTime remains the same as the specified DateTime.
Por exemplo, Zulhijjah tem 29 dias, exceto durante anos bissextos quando tem 30 dias.For example, Zulhijjah has 29 days, except during leap years when it has 30 days. Se a data especificada for o dia 30 de Zulhijjah em um ano bissexto e o valor de years for 1, a data resultante será o dia 29 do Zulhijjah no ano seguinte.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.
Se years for negativo, o resultado DateTime será anterior ao especificado DateTime .If years is negative, the resulting DateTime is earlier than the specified DateTime.
A Kind Propriedade do valor retornado DateTime sempre é igual a DateTimeKind.Unspecified .The Kind property of the returned DateTime value always equals DateTimeKind.Unspecified. Você pode preservar a Kind Propriedade do time parâmetro chamando o DateTime.SpecifyKind método, como mostra o exemplo a seguir.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.AddYears(time, years), time.Kind);
returnTime = DateTime.SpecifyKind(cal.AddYears(time, years), time.Kind)
