Is there a culture for this date-format?
2022-03-08 23:59:59
Or do I have to do this manualy with .ToString()?
>Solution :
Does it matter if there is a culture which ensures that DateTime.ToString will output this format? What matters is if you want to output a DateTime in a culturally appropriate format or not. If you don’t care about a (given) culture, why do you ask for it?
If all you need is a DateTime as a string in that format, use:
string dtAsString = DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss");
