System.Globalization String Format

Recently I was asked to format a string into a different format, after some discussion they wanted the integer 500000 to show in a format attributed to India that looks like 5,00,000

The code below shows how best to convert the number, to see the code in action go to https://dotnetfiddle.net/57rggj

using System;

public class Program
{
	public static void Main()
	{
		//Reference: http://www.c-sharpcorner.com/UploadFile/0f68f2/converting-a-number-in-currency-format-for-different-culture/
		int nNumber = 500000;
		string sText = string.Format("{0:#,###0}", nNumber);
		// 5,00,00
		Console.Write("String.Format: " + sText + Environment.NewLine);
		Console.WriteLine("n--------- Globalization - Start ---------------n");
		//For Current Culture
		Console.WriteLine("nCurrent Culture:n");
		// By default, single letter C displays currency upto two decimal digits
		Console.WriteLine(nNumber.ToString("C", System.Globalization.CultureInfo.CurrentCulture));
		// C2 displays currency upto two digits
		Console.WriteLine(nNumber.ToString("C2", System.Globalization.CultureInfo.CurrentCulture));
		// C3 displays currency upto three digits
		Console.WriteLine(nNumber.ToString("C3", System.Globalization.CultureInfo.CurrentCulture));
		// C4 displays currency upto four digits
		Console.WriteLine(nNumber.ToString("C4", System.Globalization.CultureInfo.CurrentCulture));
		// C5 displays currency upto five digits
		Console.WriteLine(nNumber.ToString("C5", System.Globalization.CultureInfo.CurrentCulture));
		Console.WriteLine("nUSA:n");
		Console.WriteLine(nNumber.ToString("C", System.Globalization.CultureInfo.CreateSpecificCulture("en-us")));
		Console.WriteLine("nDenmark:n");
		Console.WriteLine(nNumber.ToString("C", System.Globalization.CultureInfo.CreateSpecificCulture("da-DK")));
		Console.WriteLine("nIndia:n");
		Console.WriteLine(nNumber.ToString("C", System.Globalization.CultureInfo.CreateSpecificCulture("en-IN")));
		Console.WriteLine("nSpanish (Spain):n");
		Console.WriteLine(nNumber.ToString("C", System.Globalization.CultureInfo.CreateSpecificCulture("es-ES")));
		Console.WriteLine("nChinese (Taiwan):n");
		Console.WriteLine(nNumber.ToString("C", System.Globalization.CultureInfo.CreateSpecificCulture("zh-TW")));
		Console.WriteLine("nChinese (PRC):n");
		Console.WriteLine(nNumber.ToString("C", System.Globalization.CultureInfo.CreateSpecificCulture("zh-CN")));
		Console.WriteLine("nChinese (Hong Kong SAR):n");
		Console.WriteLine(nNumber.ToString("C", System.Globalization.CultureInfo.CreateSpecificCulture("zh-HK")));
		Console.WriteLine("nChinese (Singapore):n");
		Console.WriteLine(nNumber.ToString("C", System.Globalization.CultureInfo.CreateSpecificCulture("zh-SG")));
		Console.WriteLine("nChinese (Macao SAR):n");

		Console.WriteLine("nKorean (Korea):n");
		Console.WriteLine(nNumber.ToString("C", System.Globalization.CultureInfo.CreateSpecificCulture("ko-KR")));
		Console.WriteLine("nGerman (Germany):n");
		Console.WriteLine(nNumber.ToString("C", System.Globalization.CultureInfo.CreateSpecificCulture("de-DE")));
		Console.WriteLine("nHungarian (Hungary):n");
		Console.WriteLine(nNumber.ToString("C", System.Globalization.CultureInfo.CreateSpecificCulture("hu-HU")));
		Console.WriteLine("nGeorgian (Georgia):n");
		Console.WriteLine(nNumber.ToString("C", System.Globalization.CultureInfo.CreateSpecificCulture("ka-GE")));
