C# Language Tutorial => Finalizers on derived classes

Example

When an object graph is finalized, the order is the reverse of the construction. E.g. the super-type is finalized before the base-type as the following code demonstrates:

class TheBaseClass
{
    ~TheBaseClass() 
    {
        Console.WriteLine("Base class finalized!");
    }
}

class TheDerivedClass : TheBaseClass
{
    ~TheDerivedClass() 
    {
        Console.WriteLine("Derived class finalized!");
    }
}

//Don't assign to a variable
//to make the object unreachable
new TheDerivedClass();

//Just to make the example work;
//this is otherwise NOT recommended!
GC.Collect();

//Derived class finalized!
//Base class finalized!
