Is there any standard DateTime format for showing "[day] [month] [year]"?
I do not wish to use custom format strings, because it takes away the ability to have order of "day" and "month" depending on the country.
For example, for "en-us" it's "November 22", in France day is first, so it's "22 Novembre"

Just to display day and month like this, I know I can use "M" standard format string.

But how I can write "November 22, 2018" ?

Do I need to concatenate two strings like this:

$"{dt.ToString("M")}, {dt.ToString("yyyy")}"

Is there another way?

It does seem a little odd that the full option isn't available. The closest I can suggest is to use custom formatting, but rather than supply your own, grab DateTimeFormatInfo.LongDatePattern and strip out any occurrence of "dddd" (and its surrounding space/punctuation).

That should give you the variation you want across cultures while removing the weekday.

Examples:

  en-US => dddd, MMMM dd, yyyy => MMMM dd, yyyy => November 22, 2018



  fr-FR => dddd d MMMM yyyy    => d MMMM yyyy   => 22 novembre 2018

As I can understand the solution for your problem could be to create a new CultureInfo object.

I've tested it.

CultureInfo us = new CultureInfo("en-US");

string usDate = us.DateTimeFormat.ShortDatePattern;



CultureInfo fr = new CultureInfo("fr-FR");

string frDate = fr.DateTimeFormat.ShortDatePattern;



Console.WriteLine(usDate);

Console.WriteLine(frDate);



//Apply the country format here.

var localDate = DateTime.Now.ToString(frDate); 



Console.WriteLine(localDate);

So the format output will be as the location format you provide.

M/d/yyyy ---> USA format.

dd/MM/yyyy ---> France format.



22/11/2018 ---> France format applied to the current date.

For more information redirect to:
CultureInfo Class

$"{dt.ToString("MMMM dd, yyyy")}"

This will show it as November 22, 2018 assuming that dt is assigned this date.
Also, check out Custom Date Time Format String.

You can obtain the LongDatePattern from the current culture, then remove the day-of-week (dddd) and surrounding characters with a regular expression. Below, I am assuming that commas, periods, and spaces are the only separators, but if you encounter others you may want to modify the regex accordingly.

string longDatePattern = CultureInfo.CurrentCulture.DateTimeFormat.LongDatePattern;

string modifiedDatePattern = Regex.Replace(longDatePattern, @"[,.]?s?d{4}[,.]?s?", "");



Console.WriteLine(longDatePattern);      //  "dddd, MMMM d, yyyy"

Console.WriteLine(modifiedDatePattern);  //  "MMMM d, yyyy"

Now you have a custom format you can apply:

string s = DateTime.Now.ToString(modifiedDatePattern);



Console.WriteLine(s);  // "November 22, 2018"
