EPiserver: Get list of available languages for current page

Question

I am trying to get the list of available languages for the current page in EPiserver. I currently have the following:

public static IHtmlString HrefLangLinks(this PageData currentPage)
        {
            IContentRepository repo = ServiceLocator.Current.GetInstance<IContentRepository>();
            var pageLanguagesBranches = repo.GetLanguageBranches<PageData>(currentPage.ContentLink).ToList();
            var availablePageLanguages = FilterForVisitor.Filter(pageLanguagesBranches).OfType<PageData>();

            // Dictionary<String, String>
            return null;
        }

At the moment however availablePageLanguages contains: {System.Linq.Enumerable.d__95}

How can I get a list of the names of the languages? For example de-DE, en-DE or de-AT ?

Answer 1

To get the available languages of a specific page, you can read the PageData.ExistingLanguages property from your current page. That will give you an IEnumerable<CultureInfo> result. And to get the language code from each CultureInfo object, read the CultureInfo.Name property.

The code would look like this:

currentPage.ExistingLanguages.Select(culture => culture.Name);
