How to date check using mutilple date

K but i have doubt. System date : 21/11/2019 Date: 25/12/2020 In this case date is greater than System date. How it s wrk?

public static bool IsDateBeforeOrToday(string input) {DateTime pDate;if(!DateTime.TryParseExact(input, "MM/dd/yyyy", CultureInfo.InvariantCulture, DateTimeStyles.None, out pDate)){//Invalid date//log , show errorreturn false;}return DateTime.Today < pDate; }

var parameterDate = DateTime.ParseExact("12/25/2019", "MM/dd/yyyy", CultureInfo.InvariantCulture);//pass selected date here I hard-coded as "12/25/2019". var systemDate = DateTime.Today; if(parameterDate > systemDate) { }
