I am using Datetime.TryParse method to check the valid datetime. the input date string would be any string data. but is returning false as the specify date in i
Datetime.TryParse
You should be using TryParseExact as you seem to have the format fixed in your case.
TryParseExact
Something like can also work for you
DateTime.ParseExact([yourdatehere], new[] { "dd/MM/yyyy", "dd/M/yyyy" }, CultureInfo.InvariantCulture, DateTimeStyles.None);
