Solution 1

There are a couple of ways to do it:

1) Set up two loops, one inside the other and go through each string. This is easy to do, but can be slow and may give you "silly" results if the same character is repeated in each string. I would call this the "brute-force-and-ignorance" approach.
2) Sort each string into alphabetical order, and then set up a single loop to compare them.
2a) If the character in stringA is less than the character in string B, move stringA on one character
2b) If stringB is greater, than string A, move stringB on.
2c) If they are the same, count it, and move them both.

//Result will show b,c,d,g,i

string[] roles = { "a", "e", "f", "h" };
string[] allRoles = { "a", "b", "c", "d", "e", "f", "g", "h", "i" };

foreach (string nextRole in allRoles)
{
if (Array.IndexOf(roles, nextRole) == -1)
{
Response.Write(nextRole + "<br/>");
}
}

I solved my question thank you for your help.

class Program
    {
        static void Main(string[] args)
        {
            string a = "suresh";
            string b = "ramesh";
            char[] d = a.ToCharArray();
            char[] e = b.ToCharArray();
            int k = 0;
            for (int i = 0; i < 6; i++)
            {
                for (int s = 0; s < 6; s++)
                {
                    if (d[i] == e[s])
                    {
                        Console.WriteLine(d[i]);
                        k = k + 1;
                    }
                }
            }
            Console.WriteLine("The Equal Number of Characters in two Strings:-" + k);
            Console.ReadLine();
        }
    }
