year As Integer, _
era As Integer _

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.
Exceptions
| Exception | Condition |
|---|---|

Remarks
Leap years in the Korean calendar correspond to the same leap years in the Gregorian calendar. A leap year in the Gregorian calendar is defined as a Gregorian year that is evenly divisible by four, except if it is divisible by 100. However, Gregorian years that are divisible by 400 are leap years. A common year has 365 days and a leap year has 366 days.
Examples
The following code example calls the IsLeapYear method for five years in each of the eras.
Imports System.Globalization
Public Class Example
Public Shared Sub Demo(ByVal outputBlock As System.Windows.Controls.TextBlock)
' Creates and initializes a KoreanCalendar.
Dim myCal As New KoreanCalendar()
' Displays the header.
outputBlock.Text &= "YEAR" + ControlChars.Tab
Dim y As Integer
For y = 4334 To 4338
outputBlock.Text += String.Format(ControlChars.Tab + "{0}", y)
Next
outputBlock.Text &= vbCrLf
' Checks five years in the current era.
outputBlock.Text &= "CurrentEra:"
For y = 4334 To 4338
outputBlock.Text += String.Format(ControlChars.Tab + "{0}", myCal.IsLeapYear(y, KoreanCalendar.CurrentEra))
Next
outputBlock.Text &= vbCrLf
' Checks five years in each of the eras.
For i As Integer = 0 To myCal.Eras.Length - 1
outputBlock.Text += String.Format("Era {0}:" + ControlChars.Tab, myCal.Eras(i))
For y = 4334 To 4338
outputBlock.Text += String.Format(ControlChars.Tab + "{0}", myCal.IsLeapYear(y, myCal.Eras(i)))
Next
outputBlock.Text &= vbCrLf
Next
End Sub
End Class
' This example produces the following output.
' YEAR 4334 4335 4336 4337 4338
' CurrentEra: False False False True False
' Era 1: False False False True False
