DateTime.TryParse century control C#

by

It’s tricky, because the way two digit years work with TryParse is based on the TwoDigitYearMax property of the Calendar property of the CultureInfo object that you are using. (CultureInfo->Calendar->TwoDigitYearMax)

In order to make two digit years have 20 prepended, you’ll need to manually create a CultureInfo object which has a Calendar object with 2099 set as the TwoDigitYearMax property. Unfortunately, this means that any two digit date parsed will have 20 prepended (including 98, 99 etc.) which is probably not what you want.

I suspect that your best option is to use a 3rd party date parsing library instead of the standard tryparse that will use the +50/-50 year rule for 2 digit years. (that a 2 digit year should be translated into a range between 50 years before this year and 50 years greater than this year).

Alternatively, you could override the ToFourDigitYear method on the calendar object (it’s virtual) and use that to implement the -50/+50 rule.
