Collection Of Classes

Lists are array-like collections. Unlike arrays, the elements count can be dynamic - there is no need to specify it.

In order to use list, a library needs to be imported:

Syntax

Defining empty list:

Defining list with elements:

List of class objects:

List can contain class objects as elements. Example:

using System;
using System.Collections.Generic;

namespace ConsoleApp1
{
    class Car
    {
        public string model { get; set; }
        public double price { get; set; }

public Car(String model, double price)
        {
            this.model = model;
            this.price = price;
        }

public void printData()
        {
            Console.WriteLine("Model: " + this.model);
            Console.WriteLine("Price: " + this.price);
        }
    }

class CarDealership
    {
        public List<Car> cars { get; set; }
    }

class Program
    {
        static void Main(string[] args)
        {
            CarDealership carDealership = new CarDealership();

// Initialize list with values:
            carDealership.cars = new List<Car>() {
                new Car("Toyota Corolla", 25000),
                new Car("Ford Fiesta", 20000),
            };

// Add element to list;
            carDealership.cars.Add(new Car("Renault Clio", 20000));

// Cars count:
            Console.WriteLine("Car's count: " + carDealership.cars.Count);

// Looping through list elements:
            foreach (Car car in carDealership.cars)
            {
                Console.WriteLine();
                car.printData();
            }
        }
    }
}

Output:

Explanation:

At line 26 a list of classes is defined.
At line 36 the list is created. It is initialized with two objects.
At line 42 an element is added to the list.
At line 45 the count of elements is printed
at lines 49 - 53 list elements are looped.
