定義

指定した日付が閏日かどうかを確認します。Determines whether the specified date is a leap day.

public:
 override bool IsLeapDay(int year, int month, int day, int era);
public override bool IsLeapDay (int year, int month, int day, int era);
override this.IsLeapDay : int * int * int * int -> bool
Public Overrides Function IsLeapDay (year As Integer, month As Integer, day As Integer, era As Integer) As Boolean

パラメーター

year
Int32 Int32 Int32 Int32

年。A year.

month
Int32 Int32 Int32 Int32

月を表す 1 ~ 12 の整数。An integer from 1 through 12 that represents a month.

day
Int32 Int32 Int32 Int32

日を表す 1 ~ 30 の整数。An integer from 1 through 30 that represents a day.

era
Int32 Int32 Int32 Int32

時代 (年号)。An era. UmAlQuraCalendar.Eras[UmAlQuraCalendar.CurrentEra] または UmAlQuraEra を指定します。Specify UmAlQuraCalendar.Eras[UmAlQuraCalendar.CurrentEra] or UmAlQuraEra.

戻り値

指定した日が閏日である場合は true。それ以外の場合は falsetrue if the specified day is a leap day; otherwise, false. UmAlQuraCalendar クラスでは閏日がサポートされないため、戻り値は常に false です。The return value is always false because the UmAlQuraCalendar class does not support leap days.

例外

yearmonthday、または era がこの UmAlQuraCalendar クラスでサポートされている範囲外の値です。year, month, day, or era is outside the range supported by the UmAlQuraCalendar class.

次の例では、IsLeapDay時代 (年号) のそれぞれに 5 年の 2 番目の月 (2 月) の最後の日のメソッド。The following example calls the IsLeapDay method for the last day of the second month (February) for five years in each of the eras.

using namespace System;
using namespace System::Globalization;
int main()
{
   
   // Creates and initializes a HijriCalendar.
   HijriCalendar^ myCal = gcnew HijriCalendar;
   
   // Creates a holder for the last day of the second month (February).
   int iLastDay;
   
   // Displays the header.
   Console::Write( "YEAR\t" );
   for ( int y = 1421; y <= 1425; y++ )
      Console::Write( "\t {0}", y );
   Console::WriteLine();
   
   // Checks five years in the current era.
   Console::Write( "CurrentEra:" );
   for ( int y = 1421; y <= 1425; y++ )
   {
      iLastDay = myCal->GetDaysInMonth( y, 2, HijriCalendar::CurrentEra );
      Console::Write( "\t {0}", myCal->IsLeapDay( y, 2, iLastDay, HijriCalendar::CurrentEra ) );

   }
   Console::WriteLine();
   
   // Checks five years in each of the eras.
   for ( int i = 0; i < myCal->Eras->Length; i++ )
   {
      Console::Write( "Era {0}:\t", myCal->Eras[ i ] );
      for ( int y = 1421; y <= 1425; y++ )
      {
         iLastDay = myCal->GetDaysInMonth( y, 2, myCal->Eras[ i ] );
         Console::Write( "\t {0}", myCal->IsLeapDay( y, 2, iLastDay, myCal->Eras[ i ] ) );

      }
      Console::WriteLine();

   }
}
