Converting integers to roman numerals

Question

I\'m trying to write a function that converts numbers to roman numerals. This is my code so far; however, it only works with numbers that are less than 400. Is there a quick

Answer 1

I can provide a method which is comparatively simpler than the existing

using System;
using System.Collections;
using System.Collections.Generic;
using System.Data;
using System.Diagnostics;
public class Form1
{
    int[] indx = {
        1,
        2,
        3,
        4,
        5,
        10,
        50,
        100,
        500,
        1000
        // initialize array of integers 
    };
    string[] row = {
        "I",
        "II",
        "III",
        "IV",
        "V",
        "X",
        "L",
        "C",
        "D",
        "M"
        //Carasponding roman letters in for the numbers in the array
    };
        // integer to indicate the position index for link two arrays 
    int limit = 9;
        //string to store output
    string output = "";
    private void Button1_Click(System.Object sender, System.EventArgs e)
    {
        int num = 0;
        // stores the input 
        output = "";
        // clear output before processing
        num = Convert.ToInt32(txt1.Text);
        // get integer value from the textbox
        //Loop until the value became 0
        while (num > 0) {
            num = find(num);
            //call function for processing
        }
        txt2.Text = output;
        // display the output in text2
    }
    public int find(int Num)
    {
        int i = 0;
        // loop variable initialized with 0
        //Loop until the indx(i).value greater than or equal to num
        while (indx(i) <= Num) {
            i += 1;
        }
        // detemine the value of limit depends on the itetration
        if (i != 0) {
            limit = i - 1;
        } else {
            limit = 0;
        }
        output = output + row(limit);
        //row(limit) is appended with the output
        Num = Num - indx(limit);
        // calculate next num value
        return Num;
        //return num value for next itetration 
    }
