c# - Given a DateTime object, how do I get an ISO 8601 date in string format? -

-

given:

datetime.utcnow

how string represents same value in iso 8601-compliant format?

note iso 8601 defines number of similar formats. specific format looking is:

yyyy-mm-ddthh:mm:ssz 

datetime.utcnow.tostring("yyyy-mm-ddthh\\:mm\\:ss.fffffffzzz");

this gives date similar 2008-09-22t13:57:31.2311892-04:00.

another way is:

datetime.utcnow.tostring("o");

which gives 2008-09-22t14:01:54.9571247z

to specified format, can use:

datetime.utcnow.tostring("yyyy-mm-ddthh:mm:ssz")

datetime formatting options
