ASPX.CS C# - How to init an array and a List (Collection in DELPHI)

// struct is like Record in DELPHI
public struct CountryCode
{
    public string Country;
    public int Code;

    public CountryCode(string ACountry, int ACode)
    {
       Country = ACountry;
       Code = ACode;
    }
}

// init and fill the array
static readonly CountryCode[] CountriesArray =  new CountryCode[]
        {
            new CountryCode("USA", 1),
            new CountryCode("CANADA", 1),
            new CountryCode("EGYPT", 20),
            new CountryCode("GREECE", 30),
            new CountryCode("ITALY", 39)
        };

// init List with a pre-existing array
static readonly List<CountryCode> CountriesList1 = new List<CountryCode>(CountriesArray);

// init List directly
static readonly List<CountryCode> CountriesList2 = new List<CountryCode>(
            new CountryCode[]
        {
            new CountryCode("USA", 1),
            new CountryCode("CANADA", 1),
            new CountryCode("EGYPT", 20),
            new CountryCode("GREECE", 30),
            new CountryCode("ITALY", 39)
        });
