        else

            i--;

    }

    return randomString;

}

To generate the random string with only capital letters then change charArr[] to below.

// to generate random string only with capital letters

char[] charArr = "ABCDEFGHIJKLMNOPQRSTUVWXYZ".ToCharArray();

To generate the random string with only small  letters then change charArr[] to below.

// to generate random string only with small letters

char[] charArr = "abcdefghijklmnopqrstuvwxyz".ToCharArray();
