O exemplo de código a seguir exibe os valores de vários componentes de um DateTime em termos do calendário japonês.The following code example displays the values of several components of a DateTime in terms of the Japanese calendar.
using namespace System;
using namespace System::Globalization;
void DisplayValues( Calendar^ myCal, DateTime myDT )
{
Console::WriteLine( " Era: {0}", myCal->GetEra( myDT ) );
Console::WriteLine( " Year: {0}", myCal->GetYear( myDT ) );
Console::WriteLine( " Month: {0}", myCal->GetMonth( myDT ) );
Console::WriteLine( " DayOfYear: {0}", myCal->GetDayOfYear( myDT ) );
Console::WriteLine( " DayOfMonth: {0}", myCal->GetDayOfMonth( myDT ) );
Console::WriteLine( " DayOfWeek: {0}", myCal->GetDayOfWeek( myDT ) );
Console::WriteLine();
}
int main()
{
// Sets a DateTime to April 3, 2002 of the Gregorian calendar.
DateTime myDT = DateTime(2002,4,3,gcnew GregorianCalendar);
// Creates an instance of the JapaneseCalendar.
JapaneseCalendar^ myCal = gcnew JapaneseCalendar;
// Displays the values of the DateTime.
Console::WriteLine( "April 3, 2002 of the Gregorian calendar equals the following in the Japanese calendar:" );
DisplayValues( myCal, myDT );
// Adds two years and ten months.
myDT = myCal->AddYears( myDT, 2 );
myDT = myCal->AddMonths( myDT, 10 );
// Displays the values of the DateTime.
Console::WriteLine( "After adding two years and ten months:" );
DisplayValues( myCal, myDT );
}

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. A parte era do resultado DateTime será afetada se o ano resultante estiver fora da era do especificado DateTime .The era part of the resulting DateTime is affected 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, Nigatsu (fevereiro) tem 28 dias, exceto durante anos bissextos quando tem 29 dias.For example, Nigatsu (February) has 28 days except during leap years when it has 29 days. Se a data especificada for o dia 29 de Nigatsu (fevereiro) em um ano bissexto e o valor de years for 1, a data resultante será o dia 28 de Nigatsu (fevereiro) no ano seguinte.If the specified date is the 29th day of Nigatsu (February) in a leap year and the value of years is 1, the resulting date will be the 28th day of Nigatsu (February) 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)
