C# Destructor

A destructor works opposite to constructor, It destructs the objects of classes. It can be defined only once in a class. Like constructors, it is invoked automatically.

Note: C# destructor cannot have parameters. Moreover, modifiers can't be applied on destructors.

C# Constructor and Destructor Example

Let's see an example of constructor and destructor in C# which is called automatically.

1. using System;  
2.    public class Employee  
3.     {  
4.         public Employee()  
5.         {  
6.             Console.WriteLine("Constructor Invoked");  
7.         }  
8.         ~Employee()  
9.         {  
10.             Console.WriteLine("Destructor Invoked");  
11.         }  
12.     }  
13.    class TestEmployee{  
14.        public static void Main(string[] args)  
15.         {  
16.             Employee e1 = new Employee();  
17.             Employee e2 = new Employee();  
18.         }  
19.     }  

Output:

Constructor Invoked
Constructor Invoked
Destructor Invoked
Destructor Invoked

Note: Destructor can't be public. We can't apply any modifier on destructors.
