c# - How to parse datetime with DateTime.ParseExact

Question

I have the following string that I need to parse

string date = "2017-06-23T13:45:45.816"

What is correct format string?

I tried

DateTime createDate = DateTime.ParseExact(date, "yyyy-MM-dd'T'hh-mm-ss", CultureInfo.InvariantCulture);

question from:https://stackoverflow.com/questions/65873397/is-there-a-way-to-convert-string-15-jan-21-to-a-valid-datetime

Answer 1

yyyy-MM-dd'T'hh-mm-ss is not 2017-06-23T13:45:45.816 you have missing milliseconds, 12 hour clock and also wrong separators.

You'd probably need something like:

"yyyy-MM-dd'T'HH:mm:ss.fff"

Remember it's ParseExact.
