Answer 1

If you have a date string in the format of dd/MM/yyyy then it's definitely not going to parse as yyyy-MM-dd so the error you see is correct.

I think what you are looking for is to parse the date in it's current format i.e.

DateTime orderdt = DateTime.ParseExact(orderd, "dd/MM/yyyy",
    System.Globalization.CultureInfo.InvariantCulture);

but display the date as yyyy-MM-dd

orderdt.ToString("yyyy-MM-dd")
