  • year
    Type: System.Int32
    A two-digit or four-digit integer that represents the year to convert.

Return Value

Type: System.Int32
An integer that contains the four-digit representation of year.


Exception Condition

year is outside the range supported by the calendar.


TwoDigitYearMax defines the last year in the 100-year range that can be represented by ToFourDigitYear. The century is determined by finding the sole occurrence of the two-digit year within that 100-year range. For example, if TwoDigitYearMax is set to 2029, the 100-year range is from 1930 to 2029. Therefore, a two-digit value of 30 is interpreted as 1930, while a two-digit value of 29 is interpreted as 2029.

The year parameter can be either a two-digit year or a four-digit year. Passing a two-digit year value (less than 100) causes the method to convert the value to a four-digit value according to the TwoDigitYearMax value representing the appropriate century. If year is a four-digit year value that is within the supported calendar range, the method returns the actual input value. If year is a four-digit value that is outside the supported calendar range, or if it is a negative value, the method throws an exception.
