field of the p1
object.
index
using System; class Person { public string name; public int age; // We can use other classes as datatypes for a field in a class public Address address; // We can use the class itself as a datatype for a field as well public Person father; public Person mother; } class Address { public string Country; public string City; } public class ConsoleApp { public static void Main(string[] args) { Person p1 = new Person(); p1.name = "Mihaly"; p1.age = 21; Person p2 = new Person(); p2.name = "Ann"; p2.age = 52; Person p3 = new Person(); p3.name = "Nagy"; p3.age = 51; p1.mother = p2; p1.father = p3; Address address = new Address(); address.Country = "Hungary"; address.City = "Budapest"; // Assigning the address object to the address field in p1 p1.address = ___; // Note the expression 'p1.address.Country' // p1.address accesses the stored Address object // p1.address.Country accesses the Address object's Country field. Console.WriteLine($"{___} is the son of {p2.name} and {p3.name}. He is from {___}."); } }
