Check the user date input is valid format

[eimon]

Hello i am the new user and let me ask the question here.
The user will enter the date into the input dialog and i need to check whether the date entered is a format type of yyyy/mm/dd. i set the assign like below and it does not work.

isFormatDate=DateTime.TryParseExact(in_Date, “dd/MM/yyyy”,System.Globalization.CultureInfo.InvariantCulture,System.Globalization.DateTimeStyles.None,DateCheck)

Thank you

Hi,

Which format do you want to check, yyyy/mm/dd or dd/MM/yyyy?

If former, can you try the following expression?

Datetime.TryParseExact(stringVar,"yyyy/MM/dd",System.Globalization.CultureInfo.InvariantCulture,System.Globalization.DateTimeStyles.None,datetimeVar)

Regards,
