You are going to need to import System.Security.Cryptography. This will allow you to use classes for getting hash values of data.
using System;using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Security.Cryptography;
namespace Hashing
{
class Program
{
static void Main(string[] args)
{
MD5CryptoServiceProvider md5 = new MD5CryptoServiceProvider();
UTF8Encoding utf8 = new UTF8Encoding();
for (int i = 0; i < 10; i++)
{
Console.WriteLine(BitConverter.ToString(md5.ComputeHash(utf8.GetBytes(i.ToString()))));
}
Console.ReadKey();//Stops the command prompt from exiting
} //End Main
} //End Class
}

This source uses 8 bit encoding along with the MD5 hashing method. You can replace MD5 with SHA1 and get the same affect but different outputs.
You should notice that with the outputs, the hashes have this format:
05-AF-83
If you want to remove the dashes, you will need to do this:
using System;using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Security.Cryptography;
namespace Hashing
{
class Program
{
static void Main(string[] args)
{
MD5CryptoServiceProvider md5 = new MD5CryptoServiceProvider();
UTF8Encoding utf8 = new UTF8Encoding();
for (int i = 0; i < 10; i++)
{
string hash, cleanhash;
hash = cleanhash = "";
hash = BitConverter.ToString(md5.ComputeHash(utf8.GetBytes(i.ToString())));
foreach (char a in hash)
{
if (a.ToString() != "-")
{
cleanhash += a;
}
}
Console.WriteLine(cleanhash);
}
Console.ReadKey();//Stops the command prompt from exiting
} //End Main
} //End Class
}

you could just do this since the string will always be in the same win format:
BitConverter.ToString(md5.ComputeHash(utf8.GetBytes(i.ToString()))).Replace("-","");
Well, at least I am showing users how to do a foreach loop.
