ThaiBuddhistCalendar::AddYears Method

Returns a DateTime that is the specified number of years away from the specified DateTime.

Namespace:  System.Globalization
Assembly:  mscorlib (in mscorlib.dll)

public:
virtual DateTime AddYears(
	DateTime time, 
	int years
) override

Parameters

time
Type: System::DateTime
The DateTime to which to add years.
years
Type: System::Int32
The number of years to add.

Return Value

Type: System::DateTime
The DateTime that results from adding the specified number of years to the specified DateTime.

ExceptionCondition
ArgumentException

The resulting DateTime is outside the supported range.

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, February has 28 days except during leap years, when it has 29 days. If the specified date is the 29th day of February in a leap year and the value of years is 1, the resulting date is the 28th day of February in the following year.

If years is negative, the resulting DateTime is earlier than the specified DateTime.

The Kind 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.

No code example is currently available or this language may not be supported.

The following example demonstrates the use of the AddYears method.


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 ThaiBuddhistCalendar.
   ThaiBuddhistCalendar^ myCal = gcnew ThaiBuddhistCalendar;

   // Displays the values of the DateTime.
   Console::WriteLine( "April 3, 2002 of the Gregorian calendar equals the following in the ThaiBuddhist 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 );
}

/*
This code produces the following output.

April 3, 2002 of the Gregorian calendar equals the following in the ThaiBuddhist calendar:
   Era:        1
   Year:       2545
   Month:      4
   DayOfYear:  93
   DayOfMonth: 3
   DayOfWeek:  Wednesday

After adding two years and ten months:
   Era:        1
   Year:       2548
   Month:      2
   DayOfYear:  34
