Country tag helper–part 1

What I want to do is to create a Country Tag Helper for asp.net core.

Something like

<select asp-country=”true”

and then list all countries in this select. More,it should be localized ( Germany vs Allemagne). That means 1 or more resource files 

First I need initial data: The WorldBank API gives us the names http://api.worldbank.org/countries and I have made a project https://github.com/ignatandrei/WorldBankAPi that inspects that API.

To retrieve data in resource format,it is simple:

 var r = new CountriesRepository();
            var arr = r.GetCountries().Result.
                Select(it =>
                $"<data name = \"{it.iso2Code}\" xml:space=\"preserve\" >" +

                $"<value>{it.name}</value>" +
                "</data>").ToArray();
            var s = string.Join(Environment.NewLine,arr);
            File.WriteAllText(@"D:\c.txt",s);

Then we could copy paste into resources:

 <data name = "AW" xml:space="preserve" ><value>Aruba</value></data>
  <data name = "AF" xml:space="preserve" ><value>Afghanistan</value></data>
  <data name = "AO" xml:space="preserve" ><value>Angola</value></data>
 ...

Now I want to make a list of those names – so I need this code to translate between C# generated code from resource

public static string AD {
            get {
                return ResourceManager.GetString("AD",resourceCulture);
            }
        }
public static string AE {
            get {
                return ResourceManager.GetString("AE",resourceCulture);
            }
        }
...

and a list of names to be put into select.

Reflection to the rescue:

  var t =typeof( ResCTH);
            properties= t.GetProperties(
                BindingFlags.Public |
                BindingFlags.Static |
                BindingFlags.GetProperty);
            CountryISO = properties
                .Where(it=>it.Name.Length==2)
                .Select(it => it.Name)
                .ToArray();

The code is on github https://github.com/ignatandrei/CountryTagHelper and I will improve next time.
