C# get A2 Iso country code from country name

Question

I'm trying to fetch a A2 ISO country code by having a full country name as an input.

For example:

 var html = new WebClient().DownloadString("mysite.com");
            HtmlDocument htmlDoc = new HtmlDocument();
            htmlDoc.LoadHtml(html);

            var result = htmlDoc.DocumentNode.SelectNodes("//span[@class='mem_loc']").ElementAt(0).InnerText;

This will give me an out put for example:

Bosnia & Herzegovina

United States

Croatia

The input would be like:

Bosnia & Herzegovina

The outputed country code would be: BA

For United States: US

Croatia: HR

And so on...

What's the best way to do this in C#?

Answer 1

This did it in the end:

 var html = new WebClient().DownloadString("mysite.com");
            HtmlDocument htmlDoc = new HtmlDocument();
            htmlDoc.LoadHtml(html);

            var result = htmlDoc.DocumentNode.SelectNodes("//span[@class='mem_loc']").ElementAt(0).InnerText;
            var regionFullNames = CultureInfo
                       .GetCultures(CultureTypes.SpecificCultures)
                       .Select(x => new RegionInfo(x.LCID))
                       ;
            var twoLetterName = Regex.Replace(regionFullNames.FirstOrDefault(
                                   region => region.EnglishName.Contains(result)
                                ).ToString(), "{.*?}","");

Provided input: United States

Output: US
