What is destructor in C#?

  • 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.
  • A destructor, a method called once an object is disposed, can be used to cleanup resources used by the object.
  • Destructors doesn't look very much like other methods in C#. ... Once the object is collected by the garbage collector, this method is called.
  • When we are using destructors in C#, we have to keep in mind the following things:
    • A class can only have one destructor.
    • Destructors cannot be inherited or overloaded.
    • Destructors cannot be called. They are invoked automatically.
    • A destructor does not take modifiers or have parameters.

        {  
            Console.WriteLine("Constructor Invoked");  
        }  
        ~Employee()  
        {  
            Console.WriteLine("Destructor Invoked");  
        }  
    }  
   class TestEmployee{  
     public static void Main(string[] args)  
        {  
            Employee e1 = new Employee();  
            Employee e2 = new Employee();  
        }
