I tried to chew C # (indexer)

using System;
using System.Collections.Generic;

namespace IndexerLesson
{
    public class Colors
    {
        private string[] data = { "Red", "Blue", "yellow" };
       
         //Access return value this[Type argument]
        public string this[int index]{
            set{
                this.data[index] = value;
            }
            get{
                return data[index];
            }
        }

    }
}

using System;
using System.Collections.Generic;

namespace IndexerLesson
{
    public class Colors
    {
        private string[] data = { "Red", "Blue", "yellow" };

        public string this[int index]
        {
            set
            {
                this.data[index] = value;
            }
            get
            {
                return data[index];
            }
        }

    }
}

using System;
using System.Collections.Generic;

namespace IndexerLesson
{
    public class JMonth
    {
        private string[] months = { "January", "February", "Yayoi", "Uzuki", "Satsuki", "Minazuki", "July", "Hazuki", "Nagatsuki", "Kannazuki", "Shimotsuki", "December" };
        public string this[int index]
        {
            get
            {
                return months[index - 1];
            }
        }
        public int this[string name]
        {
            get
            {
                return Array.IndexOf(months, name) + 1;
            }
        }

    }
}

using System;
using System.Collections.Generic;

namespace IndexerLesson
{
    class Class1
    {
        static void Main(string[] args)
        {
            JMonth jMonth = new JMonth();
            Console.WriteLine(jMonth[6]);
            Console.WriteLine(jMonth["Kannazuki"]);
        }
    }
}
