C# ConstructorIn C#, constructor is a special method which is invoked automatically at the time of object creation. It is used to initialize the data members of new object generally. The constructor in C# has the same name as class or struct. There can be two types of constructors in C#.
C# Default ConstructorA constructor which has no argument is known as default constructor. It is invoked at the time of creating object. C# Default Constructor Example: Having Main() within classusing System; public class Employee { public Employee() { Console.WriteLine("Default Constructor Invoked"); } public static void Main(string[] args) { Employee e1 = new Employee(); Employee e2 = new Employee(); } } Output: Default Constructor Invoked Default Constructor Invoked C# Default Constructor Example: Having Main() in another classLet's see another example of default constructor where we are having Main() method in another class. using System; public class Employee { public Employee() { Console.WriteLine("Default Constructor Invoked"); } } class TestEmployee{ public static void Main(string[] args) { Employee e1 = new Employee(); Employee e2 = new Employee(); } } Output: Default Constructor Invoked Default Constructor Invoked C# Parameterized ConstructorA constructor which has parameters is called parameterized constructor. It is used to provide different values to distinct objects. using System; public class Employee { public int id; public String name; public float salary; public Employee(int i, String n,float s) { id = i; name = n; salary = s; } public void display() { Console.WriteLine(id + " " + name+" "+salary); } } class TestEmployee{ public static void Main(string[] args) { Employee e1 = new Employee(101, "Sonoo", 890000f); Employee e2 = new Employee(102, "Mahesh", 490000f); e1.display(); e2.display(); } } Output: 101 Sonoo 890000 102 Mahesh 490000
