C# Constructor1 min read

In C#, a constructor is the member of the class and is automatically invoked once the object of the class is created. It is like a method in a program and is used for the initialization of the data members of a newly created object.

Two types of C# constructors

  1. Default constructor
  2. Parameterized constructor

Default Constructor in C#

A constructor without any parameters is called a default constructor and is invoked at the time of creating the object of the class.

Example: Default C# Constructor

Output:

Constructor Called
Constructor Called

As you can see, that the constructor is called every time we create a new object of the class. And since it is a default constructor, it has no parameter.


Parameterized Constructor in C#

A Constructor having a specific number of parameters is called Parameterized Constructor. Passing parameters is useful when you want to assign a different initial value to distinct objects.

Example: Parameterized C# Constructor

Output:

1101 Shaun 80.5
1102 Garen 90

As you can see the student details are initialized and displayed for every object created for the Student class in a program.
