How to convert from EBCDIC to ASCII in C#.net

Question

I have a value in EBCDIC format "000000{". I want to convert it into a.Net Int32 type. Can anyone let me know what I can do about it?? So my question is given a string that contains a signed numeric in EBCDIC , what should I be doing to convert it into a .NET Int32.

Thanks so much in advance!

The following program has worked for converting an EBCDIC value to an integer, when receiving data from one of our customers. The data we get may be a subset of what you might get, so see if this works for you:

using System;
using System.Text;

namespace ConsoleApplication6
{
    class Program
    {
        static void Main(string[] args)
        {
            string strAmount = "00007570{";
            Console.WriteLine("{0} is {1}", strAmount, ConvertEBCDICtoInt(strAmount));
            strAmount = "000033}";
            Console.WriteLine("{0} is {1}", strAmount, ConvertEBCDICtoInt(strAmount));
            Console.ReadLine();
        }

        // This converts "00007570{" into "75700", and "000033}" into "-330"
        public static int? ConvertEBCDICtoInt(string i_strAmount)
        {
            int? nAmount = null;

            if (string.IsNullOrEmpty(i_strAmount))
                return(nAmount);

            StringBuilder strAmount = new StringBuilder(i_strAmount);
            if (i_strAmount.IndexOfAny(new char[] { '}', 'J', 'K', 'L', 'M', 'N', 'O', 'P', 'Q', 'R' }) >= 0)
                strAmount.Insert(0, "-");

            strAmount.Replace("{", "0");
            strAmount.Replace("}", "0");
            strAmount.Replace("A", "1");
            strAmount.Replace("J", "1");
            strAmount.Replace("B", "2");
            strAmount.Replace("K", "2");
            strAmount.Replace("C", "3");
            strAmount.Replace("L", "3");
            strAmount.Replace("D", "4");
            strAmount.Replace("M", "4");
            strAmount.Replace("E", "5");
            strAmount.Replace("N", "5");
            strAmount.Replace("F", "6");
            strAmount.Replace("O", "6");
            strAmount.Replace("G", "7");
            strAmount.Replace("P", "7");
            strAmount.Replace("H", "8");
            strAmount.Replace("Q", "8");
            strAmount.Replace("I", "9");
            strAmount.Replace("R", "9");

            // Convert the amount to a int:
            int n;
            if (int.TryParse(strAmount.ToString(), out n))
                nAmount = n;
            return (nAmount);
        }
    }
}
