Simple code to convert a number or amount from 0 to 999,999. This was originally written in VB6(by me) but since I've been trying to learn C# lately I ported this to C# as my basic exercise. I know it's just a simple code but I'm still posting this, it might useful to someone. Here's the code:
using Microsoft.VisualBasic;
using System;
using System.Collections;
using System.Collections.Generic;
using System.Diagnostics;
namespace CodeMonkey
{
class AmountToWords
{
static void Main()
{
Console.WriteLine("Enter amount: ");
string amnt = Console.ReadLine();
Console.WriteLine("{0} = {1}", amnt, NumToText(amnt));
Console.ReadKey();
}
static string Ones(string strNum)
{
string tmp = "";
switch (strNum) {

break;
