示例

下面的代码示例将GetDaysInMonth在每个纪元的五年中, 为第二个月调用。The following code example calls GetDaysInMonth for the second month in each of five years in each era.

using namespace System;
using namespace System::Globalization;
int main()
{
   
   // Creates and initializes a JapaneseCalendar.
   JapaneseCalendar^ myCal = gcnew JapaneseCalendar;
   
   // Displays the header.
   Console::Write( "YEAR\t" );
   for ( int y = 1; y <= 5; y++ )
      Console::Write( "\t {0}", y );
   Console::WriteLine();
   
   // Displays the value of the CurrentEra property.
   Console::Write( "CurrentEra:" );
   for ( int y = 1; y <= 5; y++ )
      Console::Write( "\t {0}", myCal->GetDaysInMonth( y, 2, JapaneseCalendar::CurrentEra ) );
   Console::WriteLine();
   
   // Displays the values in the Eras property.
   for ( int i = 0; i < myCal->Eras->Length; i++ )
   {
      Console::Write( "Era {0}:\t", myCal->Eras[ i ] );
      for ( int y = 1; y <= 5; y++ )
         Console::Write( "\t {0}", myCal->GetDaysInMonth( y, 2, myCal->Eras[ i ] ) );
      Console::WriteLine();

   }
}

注解

例如, 对于 Nigatsu (二月, month = 2), 此方法返回28或 29, 具体取决于是否year为闰年。For example, this method returns 28 or 29 for Nigatsu (February, month = 2), depending on whether year is a leap year.
