What is difference between destructer and dispose and finalize?

Question

Destructor : They are special methods that contains clean up code for the object. You can not call them explicitly in your code as they are called implicitly by GC. In C# they have same name as the class name preceded by the "~" Dispose : These are just like any other methods in the class and can be called explicitly but they have a special purpose of cleaning up the object. In the dispose method we write clean up code for the object. It is important that we freed up all the unmanaged recources in the dispose method like database connection, files etc. The class implementing dispose method should implement IDisposable interface.A Dispose method should call the GC.SuppressFinalize method for the object it is disposing if the class has desturctor because it has already done the work to clean up the object, then it is not necessary for the garbage collector to call the object's Finalize method. Finalize : A Finalize method acts as a safeguard to clean up resources in the event that your Dispose method is not called. You should only implement a Finalize method to clean up unmanaged resources. You should not implement a Finalize method for managed objects, because the garbage collector cleans up managed resources automatically. Finalize method is called by the GC implicitly therefore you can not call it from your code. Note: In C#, Finalize method can not be override, so you have to use destructor whose internal implementation will override the Finalize method in MSIL.But in the VB.NET, Finalize method can be override because it does support destructor method.

Destructor implicitly calls the Finalize method, they are technically the same. Dispose is available with objects that implement the IDisposable interface. The destructor implicitly calls Finalize on the base class of the object. https://www.c-sharpcorner.com/UploadFile/nityaprakash/back-to-basics-dispose-vs-finalize/
