Hi,

DateTime.TryParseExact(dateAsString, “yyyy-MM-dd”, Nothing, Nothing , resultAsDate) will return a boolean and the potentially converted dateTime. True if format matches → False if not.
Note that the method takes iFormatProvider and DateTimeStyles as arguments which I just gave ‘Nothing’ in this test.

Thank you for the response.

I also got one method DateTime.TryParse(“2018-12-31”,InputDate).ToString
2018-12-31 → format in which you expect the date
InputDate → input date

Yes but TryParse will accept any format, e.g. “31.12.2018”. According to your initial requirements this should not be accepted.

TryParse(inputString, outputDate)
