Sanjay.C,

I researched and found information on the abstract class from which all
implementations of the MD5 hash algorithm inherit using C#

I obtained this code from one our new sites:
****************************************************************************
*******************************************
using System;
using System.Security.Cryptography;
using System.Text;

class Example
{
   // Hash an input string and return the hash as
   // a 32 character hexadecimal string.
   static string getMd5Hash(string input)
   {
       // Create a new instance of the MD5CryptoServiceProvider object.
       MD5 md5Hasher = MD5.Create();

       // Convert the input string to a byte array and compute the hash.
       byte[] data =
md5Hasher.ComputeHash(Encoding.Default.GetBytes(input));

       // Create a new Stringbuilder to collect the bytes
       // and create a string.
       StringBuilder sBuilder = new StringBuilder();

       // Loop through each byte of the hashed data
       // and format each one as a hexadecimal string.
       for (int i = 0; i < data.Length; i++)
       {
           sBuilder.Append(data[i].ToString("x2"));
       }

       // Return the hexadecimal string.
       return sBuilder.ToString();
   }

   // Verify a hash against a string.
   static bool verifyMd5Hash(string input, string hash)
   {
       // Hash the input.
       string hashOfInput = getMd5Hash(input);

       // Create a StringComparer an comare the hashes.
       StringComparer comparer = StringComparer.OrdinalIgnoreCase;

       if (0 == comparer.Compare(hashOfInput, hash))
       {
           return true;
       }
       else
       {
           return false;
       }
   }

   static void Main()
   {
       string source = "Hello World!";
       
       string hash = getMd5Hash(source);

       Console.WriteLine("The MD5 hash of " + source + " is: " + hash +
".");

       Console.WriteLine("Verifying the hash...");

       if (verifyMd5Hash(source, hash))
       {
           Console.WriteLine("The hashes are the same.");
       }
       else
       {
           Console.WriteLine("The hashes are not same.");
       }
       
   }
}
// This code example produces the following output:
//
// The MD5 hash of Hello World! is: ed076287532e86365e841e92bfc50d8c.
// Verifying the hash...
// The hashes are the same.
