Formatting DateTime - ignore culture

Question

I need to format a date to the following format:

M-d-yyyy

I tried using:

string.Format("{0:M-d-yyyy}", DateTime.Now)

But the output string will depend on the CurrentCulture on the computer where it's run, so sometimes the output might be 07/09/2014 or 07.09.2014 instead of 09-07-2014.

How can I easily prevent it from converting it based on the culture and treating it as a literal string?

Answer 1

Use CultureInfo.InvariantCulture as the culture or provider argument.

String.Format(CultureInfo.InvariantCulture, "{0:M-d-yyyy}", DateTime.Now)

Answer 2

Use CultureInfo.InvariantCulture as an IFormatProvider parameter:

DateTime.Now.ToString("M-d-yyyy", CultureInfo.InvariantCulture);
