Remarks

TwoDigitYearMax is the last year in the 100-year range that can be represented by a two-digit year. 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 1429, the 100-year range is from 1330 to 1429; therefore, a 2-digit value of 30 is interpreted as 1330, while a 2-digit value of 29 is interpreted as 1429.

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 the application supplies a four-digit year value that is within the supported calendar range to ToFourDigitYear, the method returns the actual input value. If the application supplies a four-digit value that is outside the supported calendar range, or if it supplies a negative value, the method throws an exception.
