Finalize() vs Dispose()

Question

Hi, What is the main difference between Finalize() and Dispose()?

Satyapriya Nayak · Answer

Hi Akash, Finalize and Dispose are both known as Finalizers. They are the methods used to deallocate the memory of the objects Differences: FINALIZE 1)Finalize belongs to the Object class. 2)It is automatically called by the Garbage Collection mechanism when the object goes out of the scope(usually at the end of the program) It is not called by the User Code. In C#, suppose there is a class known as emp class emp { //This is the destructor of emp class ~emp() { } //This destructor is implicitly compiled to the Finalize method. } 3)Not suitable for instant disposing of the objects.Sloer method. DISPOSE 1)Dispose belongs to the IDisposable interface 2)we have to manually write the code to implement it(User Code) ex: if we have emp class we have to inherit it from the IDisposable interface and write code. We may have to suppress the Finalize method using GC.SuppressFinalize() method. 3)Faster method for instant disposal of the objects Example: user interface Controls. Forms, SqlConnection class have built in implementaion of Dispose method. Thanks

Finalize: nondeterministic destructor/finalizer called automatically by the Garbage Collector when there are no more references to this instance. Dispose: deterministically called by the developer on an object implementing IDisposable to free resources. The simply you can say the finalize is no guarantee to run and it happens implicitly.Where Dispose is explicitly called by the developers.
