 override int ToFourDigitYear(int year);
public override int ToFourDigitYear (int year);
override this.ToFourDigitYear : int -> int
Public Overrides Function ToFourDigitYear (year As Integer) As Integer



An integer (usually two digits) that represents the year to convert.


An integer that contains the four-digit representation of year.


year is outside the range supported by the calendar.


This method implements Calendar.ToFourDigitYear.

Because the year in the Japanese calendar is typically less than four digits long, this implementation always returns the value of the year parameter.

ToFourDigitYear supports either a two-digit year or a four-digit year. However, a valid year is generally represented as two digits (less than 100). Passing a two-digit year value causes the method to convert the value to a four-digit value according to the TwoDigitYearMax value representing the appropriate century. If the application supplies a four-digit value, or if it supplies zero or a negative value, ToFourDigitYear throws an exception.
