Answer 1

If I understood right you need to create unique for each number from 0 to 8 So you can do this by using array, list or more dynamically by using Dictionnary

Using Array:

string[] numbersUnique = new string[] {"zero","one"....."eight"};
 Console.WriteLine("The unique key of {0} is {1}", 2, numbersUnique [2]);

Using Dictionary:

   Dictionary<int, string> numbers = new Dictionary<int, string>()
                {
                {0,"zero"},
                {1,"one"},
                {2,"two"},
                {3,"three"},
                // .
                // .
                {8,"eight"}
                };

                Console.WriteLine("The unique key of {0} is {1}", 2, numbers[2]);
