Define Dictionary in arrays

Question

Rajeesh Menoth · Answer

Hi, What exactly do you need Kiran? As per your question, define a dictionary array as Jignesh already explained. Don't be confused with side arrays. It's an array that stores key-value pairs, similar to other collection types. Here, you can add different types of keys. In Jignesh's example, he added a key as a string and a value as an integer. Similarly, you can use different types for keys and values. You can also add a list of strings as a key. Everything depends on your business requirements.

Hello Kiran, You can create Dictionary in side array, using System; using System.Collections.Generic; public class Program { public static void Main() { // How to create array of dictionaries Dictionary [] arrayOfDictionaries = new Dictionary [3]; // Initialize dictionaries and add values in Array arrayOfDictionaries[0] = new Dictionary { { "apple", 1 }, { "banana", 2 } }; arrayOfDictionaries[1] = new Dictionary { { "car", 3 }, { "bus", 4 } }; arrayOfDictionaries[2] = new Dictionary { { "dog", 5 }, { "cat", 6 } }; // Access dictionary values in the array of dictionaries foreach (var dict in arrayOfDictionaries) { foreach (var kvp in dict) { Console.WriteLine($"{kvp.Key}: {kvp.Value}"); } } } }
