using System;
using System.Collections.Generic;

namespace ConsoleApp
{
    class Program
    {
        static void Main(string[] args)
        {
            // Declaring a new empty dictionary
            ___ ___ = new Dictionary<string, string>();

            // Adding data to the dictionary
            ___("name", "The Hobbit");
            ___("author", "J. R. R. Tolkien");
            ___("publication date", "21 September 1937");

            // Outputting data
            Console.WriteLine("Book Name: " + ___);
            Console.WriteLine("Author: " + ___);
            Console.WriteLine("Publication Date: " + ___);
        }
    }
}

Use the Add method for adding data to the dictionary.
You can access values from the dictionary using the dictionaryName[keyName] syntax.

              123456789101112131415161718192021222324
            
using System;
using System.Collections.Generic;

namespace ConsoleApp
{
    class Program
    {
        static void Main(string[] args)
        {
            // Declaring a new empty dictionary
            var book = new Dictionary<string, string>();

            // Adding data to the dictionary
            book.Add("name", "The Hobbit");
            book.Add("author", "J. R. R. Tolkien");
            book.Add("publication date", "21 September 1937");

            // Outputting data
            Console.WriteLine("Book Name: " + book["name"]);
            Console.WriteLine("Author: " + book["author"]);
            Console.WriteLine("Publication Date: " + book["publication date"]);
        }
