It uses DateTimeFormatInfo.CurrentInfo which contains the different formats.

By default, it will be from regional and language settings of your computer.

You could probably infer it in some cases from CultureInfo.CurrentCulture. But I don't think it's possible to be certain which one it was since multiple formats might be valid in one culture.

If you want to be sure, try using TryParseExact instead.

If you are using DateTime.TryParse(string s,out DateTime result), the output format depends on your machine's CultureInfo.
