.Net Framework provides two methods Finalize and Dispose for releasing unmanaged resources like files, database connections, COM etc.

Dispose	Finalize
It is used to free unmanaged resources like files, database connections etc. at any time	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.
Explicitly, it is called by user code and the class which is implementing dispose method, must has to implement IDisposable interface.	Internally, it is called by Garbage Collector and cannot be called by user code.
It belongs to IDisposable interface.	It belongs to Object class.
It's implemented by implementing IDisposable interface Dispose() method	It's implemented with the help of destructor in C++ & C#.
There is no performance costs associated with Dispose method.	There is performance costs associated with Finalize method since it doesn't clean the memory immediately and called by GC automatically.
This method uses interface – “IDisposable” interface and it will free up both managed and unmanaged codes like – database connection, files etc.	This method is called internally unlike Dispose method which is called explicitly. It is called by garbage collector and can’t be called from the code.
