How to get DayNames from language only in .NET

Question

Assume that I only have a country code (en, de, fr) and I need to display the weekdays in this language. I know about RegionInfo and CultureInfo - but I can't find a solution. If I create a country info from (for an example) "en" I have no DateTime info in it. It would also be OK to just take the first matching Region. For an example en-US for en or de-DE for de.

I don't know if there are differences in DayNames but I know there are some for the months. de-DE Februar - de-AT Feber -- anyhow I don't care. Event if it may be "a bit different" (to see Februar instead of Feber) - it is still German.

And that's what I want to achive - get en an write Monday - get de and write Montag...

Is there a way to create a region just from a language code?

Answer 1

This piece may be helpful: to go from "en" to the CultureInfo, a quicker way is

CultureInfo ci = CultureInfo.CreateSpecificCulture("en")

For the second part, I believe you are asking for day names, so you would write

string[] names = ci.DateTimeFormat.DayNames 

Answer 2

DateTime.Today.ToString("dddd", new CultureInfo("zh-TW"))

Above code will print Monday as 星期一 (Chinise locale).

Answer 3

It's usually when you say "I don't care" that you start fighting the APIs.

Anyway, this should work:

var list = CultureInfo.GetCultures(CultureTypes.SpecificCultures);
var ci = list.FirstOrDefault(c => c.IetfLanguageTag.StartsWith("de"));

var ri = new RegionInfo(ci.Name);
Console.WriteLine("Today = {0:dddd MMMM yyyy}", DateTime.Today);

Answer 4

Dim days As String() Dim months As String() Dim cul As New System.Globalization.CultureInfo("de-DE") months = cul.DateTimeFormat.MonthNames days = cul.DateTimeFormat.DayNames

Answer 5

Try this:-

string culture = "your culture"

CultureInfo myCulture = new CultureInfo(culture);

DateTimeFormatInfo dtfi = myCulture .DateTimeFormat;

dayString = dtfi.GetDayName( your date here.. );

Answer 6

As "de" is a NeutralCulture it won't be possible to get the DayNames out of the DateTimeFormat if you try CultureInfo.GetCultureInfo("de").

I would suggest that you run the CultureInfo.CreateSpecificCulture("de") in this case since it'll create a non-neutral culture...in case of "de" I got a culture of "de-DE" back from the .NET gods :D

    CultureInfo tmp = CultureInfo.CreateSpecificCulture("de");

    string[] names = tmp.DateTimeFormat.DayNames;
    foreach(string name in names)
    {
        Console.WriteLine(name);
    }

Answer 7

This will give you a list of cultures:

    Dim ci As CultureInfo
    For Each ci In CultureInfo.GetCultures(CultureTypes.SpecificCultures)
        Console.WriteLine(ci.Name)
    Next
