I need to get the numeric codes of ISO 3166-1 countries in C#.
It seems with the RegionInfo class I can only get the Alpha2 and Alpha3 codes. Is it possible to get the ISO 3166-1 numeric codes in C#?
How to get the numeric code of all ISO 3166-1 countries in C#
AFAIK, there's no such a information in the framework...well, maybe in some low-level API, though. However, why don't put the codes inside a text file and parse them by C# code? I done the same thing for the Alpha-2 codes. –

I've created a extension method for RegionInfo in order to retrieve the numeric value. It's similar to the solution mentioned by Dmitry Bychenko, but I need an extension method and I want a current version of the iso 3166 records:
//usage
RegionInfo regionInfo = new RegionInfo("US");
int numericIsoCodeUS = regionInfo.NumericIsoCode();
Extension method class:
using System;
using System.Collections.Generic;
using System.Globalization;
namespace ISO3166_1Test
{
public static class Iso3166Helper
{
private static Dictionary<string, int> Iso3166NumericDictionary { get; set; }
/// <summary>
/// This is an extension method for class RegionInfo
/// It will return the ISO 3166-1 numeric value of a given RegionInfo
///
/// If there is no numeric value for a given regionInfo(e.g. Serbia and Montenegro (Former) or Caribbean), and exception will be thrown
/// </summary>
/// <param name="regionInfo">The RegionInfo object used for the extension method</param>
/// <returns>the numeric ISO 31666-1 value of a given RegionInfo </returns>
public static int NumericIsoCode(this RegionInfo regionInfo)
{
if (!Iso3166NumericDictionary.ContainsKey(regionInfo.TwoLetterISORegionName))
{
throw new Exception(string.Format("There is no numeric value for regionInfo {0}", regionInfo.Name));
}
return Iso3166NumericDictionary[regionInfo.TwoLetterISORegionName];
}
static Iso3166Helper()
{
Iso3166NumericDictionary = new Dictionary<string, int>{
