HijriCalendar.IsLeapYear Method (Int32, Int32)

Determines whether the specified year in the specified era is a leap year.

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

public override bool IsLeapYear(
	int year,
	int era
)

Parameters

year
Type: System.Int32
An integer that represents the year.
era
Type: System.Int32
An integer that represents the era.

Return Value

Type: System.Boolean
true if the specified year is a leap year; otherwise, false.

ExceptionCondition
ArgumentOutOfRangeException

era is outside the range supported by this calendar.

-or-

year is outside the range supported by this calendar.

In every 30-year cycle that ends with a year that is evenly divisible by 30, the 2nd, 5th, 7th, 10th, 13th, 16th, 18th, 21st, 24th, 26th, and 29th years are leap years. A common year has 354 days and a leap year has 355 days.

The following code example calls the IsLeapYear method for five years in each of the eras.


using System;
using System.Globalization;


public class Example
{

   public static void Demo(System.Windows.Controls.TextBlock outputBlock)
   {

      // Creates and initializes a HijriCalendar.
      HijriCalendar myCal = new HijriCalendar();

      // Displays the header.
      outputBlock.Text += "YEAR\t";
      for (int y = 1421; y <= 1425; y++)
         outputBlock.Text += String.Format("\t{0}", y);
      outputBlock.Text += "\n";

      // Checks five years in the current era.
      outputBlock.Text += "CurrentEra:";
      for (int y = 1421; y <= 1425; y++)
         outputBlock.Text += String.Format("\t{0}", myCal.IsLeapYear(y, HijriCalendar.CurrentEra));
      outputBlock.Text += "\n";

      // Checks five years in each of the eras.
      for (int i = 0; i < myCal.Eras.Length; i++)
      {
         outputBlock.Text += String.Format("Era {0}:\t", myCal.Eras[i]);
         for (int y = 1421; y <= 1425; y++)
            outputBlock.Text += String.Format("\t{0}", myCal.IsLeapYear(y, myCal.Eras[i]));
         outputBlock.Text += "\n";
      }

   }

}
