using System;

public class TestFormatting

{

   public static void Main()

   {

      long acctNumber;

 

      acctNumber = 104254567890;

      Console.WriteLine(String.Format(new AcctNumberFormat(), "{0:H}", acctNumber));

      Console.WriteLine(String.Format(new AcctNumberFormat(), "{0}", acctNumber));

 

      acctNumber = 14567890;

      Console.WriteLine(String.Format(new AcctNumberFormat(), "{0:H}", acctNumber));

      Console.WriteLine(String.Format(new AcctNumberFormat(), "{0}", acctNumber));

 

      acctNumber = 18779887654111;

      Console.WriteLine(String.Format(new AcctNumberFormat(), "{0:H}", acctNumber));

      Console.WriteLine(String.Format(new AcctNumberFormat(), "{0}", acctNumber));

// The example displays the following output to the console:
