How to get country code (e.g. +61) in asp.net?

Question

I want to retrieve all country codes (like +61 for Australia) by giving country name. Is there built in method for retrieving country code in c# like

int countryCode = CultureInfo.getCountryCode("CountryName");

I saw some methods on internet but non of them is simple. I want simple method for retrieving country code by giving country name. I saw Google libphonenumber but is there any simple solution because I am having trouble while including thi library because I am using visual studio 2015 but this library is build in visual studio 2017. If this library is only the solution then how can I include this library in my visual studio 2015 project?

This is the code for getting all countries

public static List<string> countryList()
    {
        List<string> cultureList = new List<string>();
        CultureInfo[] info = getCultureInfo();

        foreach (CultureInfo culture in info)
        {
            RegionInfo region = new RegionInfo(culture.LCID);

            if (!(cultureList.Contains(region.EnglishName)))
            {
                cultureList.Add(region.EnglishName);
            }
        }

        cultureList.Sort();
        return cultureList;
    }

Now, how can I get country codes all of theses?

Answer 1

To answer your question, if you are talking about telephone prefix as country code, then there is no builtin way as I am aware of. Neither, culture nor region contains that information.

The easiest way is to take advantage of some free API, for example geognos , where you can get the json data of a country using the code you can get from culture/region. For example data for Australia would be found using the AU-code .

Edit.

To clarify my answer a bit, country code has nothing to do with tel. prefix and country codes at different formats can be fetched from culture/region information.
