Programmatic way to get all the available languages (in satellite assemblies)

Question

I'm designing a multilingual application using .resx files.

I have a few files like GlobalStrings.resx, GlobalStrings.es.resx, GlobalStrings.en.resx, etc. When I want to use this, I just need to set Thread.CurrentThread.CurrentCulture.

The problem: I have a combobox with all the available languages, but I'm loading this manually:

comboLanguage.Items.Add(CultureInfo.GetCultureInfo("en"));
comboLanguage.Items.Add(CultureInfo.GetCultureInfo("es"));

I've tried with

cmbLanguage.Items.AddRange(CultureInfo.GetCultures(CultureTypes.UserCustomCulture));

without any success. Also tried with all the elements in CultureTypes, but I'm only getting a big list with a lot more languages that I'm not using, or an empty list.

Is there any way to get only the supported languages?

Answer 1

Using what Rune Grimstad said I end up with this:

string executablePath = Path.GetDirectoryName(Application.ExecutablePath);
string[] directories = Directory.GetDirectories(executablePath);
foreach (string s in directories)
{
    try
    {
        DirectoryInfo langDirectory = new DirectoryInfo(s);
        cmbLanguage.Items.Add(CultureInfo.GetCultureInfo(langDirectory.Name));
    }
    catch (Exception)
    {

    }
}

or another way

int pathLenght = executablePath.Length + 1;
foreach (string s in directories)
{
    try
    {
        cmbLanguage.Items.Add(CultureInfo.GetCultureInfo(s.Remove(0, pathLenght)));
    }
    catch (Exception)
    {

    }
}

I still don't think that this is a good idea ...
