  What is Constructor in C#?
  A Constructor is a special type of method which is invoked when we create an instance of the class. It has the same name as the class name. A constructor does not have any return type not even void. It is used to assign the initial value to the data member of the class.
  For Example, If I have a class called MyClass then the Constructor of the class is created as follows,
  public class MyClass { public MyClass() { //Constructor } }
  In the above code snippet, we have a class called MyClass and the constructor of this class is created with the same as the class name.
  Types of Constructor:
  There are following types of Constructor in C#.
  - Default Constructor.
  - Parameterized Constructor.
  - Copy Constructor.
  - Private Constructor.
  - Static Constructor.
  We will discuss Default and Parameterized Constructor in this tutorial. Rest of the types we will discuss in next sessions.
  Default Constructor:
  A constructor with no parameters is called a default constructor. The default constructor initializes all numeric fields to zero and all string and object fields to null inside a class.
  using System; public class Student { public Student() { Console.WriteLine("Default Constructor Invoked"); } } class TestStudent{ public static void Main(string[] args) { Student objStudent1 = new Student(); Student objStudent2 = new Student(); } }
  Output:
  Default Constructor Invoked Default Constructor Invoked
  Parameterized Constructor:
  A Constructor with at least one parameter is called Parameterized Constructor. It can initialize each instance of the class to new values.
  using System; public class Student { public int _iRollNo; public String _sName; public Student(int iRollNo, String sName) { _iRollNo = iRollNo; _sName = sName; } public void DisplayRecord() { Console.WriteLine("Roll No " + " " + _iRollNo + ". Name " + _sName); } } class Program { static void Main(string[] args) { Student objStudent = new Student(1,"Vinod"); Student objStudent1 = new Student(2, "Ansh"); objStudent.DisplayRecord(); objStudent1.DisplayRecord(); Console.ReadLine(); } }
  Output:
  Roll No 1. Name Vinod Roll No 2. Name Ansh
  Point Of Interest for Constructor:
  - A constructor has the same name as the class name.
  - A constructor doesn’t have the return type not even void.
  - A class can have any number of the constructor.
  - A constructor cannot be declared as abstract final.
  - A static constructor cannot be parameterized.
