DateTime? to string yyyy-mm-dd

Question

I have a method that takes a parameter of the type DateTime?

I need to convert what I receive to a string of the format - yyyy-mm-dd

What is the cleanest optimal way to achieve this?

`datetime.ToString("yyyy-mm-dd");`? – Cody Gray Aug 01 '14 at 05:05 — Cody Gray, Aug 01 '14 at 05:05

Assuming dateParameter if of type DateTime, just like you said:

dateParameter.ToString("yyyy-mm-dd");

EDIT:

Since you edited your post to nullable DateTime, here's an edit:

dateParameter.Value.ToString("yyyy-mm-dd");

You can use DateTime.ToString ..below is the sample code :-

datePassed.ToString("yyyy-mm-dd");

And for nullable DateTime :-

datePassed.Value.ToString("yyyy-mm-dd");

Why would he do `DateTime.ParseExact` if he accepts a parameter of `DateTime`? Maybe I'm missing something. – B.K. Aug 01 '14 at 05:01
