Decrement a static variable of a class after an object it has been destroyed

Question

Hi Say I have a class Student which has a static field Count . I need to increment it whenever a new object of Student is created and decrement it whenever any object of Student is destroyed. I know that increment can be done in the constructor but what about decrement since there is no destructor.

The Student class has to implement the IDisposable interface class Student : IDisposable { .................... public void Dispose() { Student.Decrement(); } }
