What is difference between dispose and finalize method C#?

Question

Can you tell me the difference between dispose and finalize method in C#?

Vivek Kumar · Answer

Dispose 1) It is used to free unmanaged resources like files, database connections etc. at any time. 2) Explicitly, it is called by user code and the class which is implementing dispose method, must has to implement IDisposable interface. 3) There is no performance costs associated with Dispose method. Finalize 1) It can be used to free unmanaged resources (when you implement it) like files, database connections etc. held by an object before that object is destroyed. 2) Internally, it is called by Garbage Collector and cannot be called by user code. 3) There is performance costs associated with Finalize method since it doesn't clean the memory immediately and called by GC automatically.
