How to get DayNames from the language only in .NET.

Question

Suppose I have a country code (en, de, fr) and I need to display weekdays in this language. I know about RegionInfo and CultureInfo, but I can not find a solution. If I create country information from (for example) "en", I don't have DateTime data. It would also be easy to take the first relevant region. For example, en-US for en or de-DE for de.

I do not know if there are differences in DayNames, but I know that there are several months. de-DE Februar - de-AT Feber - anyway, I don't care. The event, if it can be “a little different” (to see Fevroir instead of Feber), is still German.

And this is what I want to achieve - write on Monday - get de and write Montag ...

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

Answer 1

This part may be useful: go from "en" to CultureInfo, a faster way

CultureInfo ci = CultureInfo.CreateSpecificCulture("en")

For the second part, I believe that you are asking for the names of the days, so you write

string[] names = ci.DateTimeFormat.DayNames 

Answer 2

Usually, when you say "I don't care", you start to struggle with the API.

In any case, 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 3

:

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

Answer 4

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

星期一 ( Chinise).

Answer 5

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

Answer 6

: -

string culture = " "

CultureInfo myCulture = new CultureInfo ();

DateTimeFormatInfo dtfi = myCulture.DateTimeFormat;

dayString = dtfi.GetDayName( ..);

Since "de" is a neutral culture, you cannot get DayNames from DateTimeFormat if you try CultureInfo.GetCultureInfo ("de").

I would suggest that you run CultureInfo.CreateSpecificCulture ("de") in this case, since it will create a non-neutral culture ... in the case of "de" I got the culture "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);
    }
