final, finally and finalize in C#

CsharpProgrammingServer Side Programming


Java has final keyword, but C# does not have its implementation. For the same implementation, use the sealed keyword.

With sealed, you can prevent overriding of a method. When you use sealed modifiers in C# on a method, then the method loses its capabilities of overriding. The sealed method should be part of a derived class and the method must be an overridden method.


The finally block is used to execute a given set of statements, whether an exception is thrown or not thrown. For example, if you open a file, it must be closed whether an exception is raised or not.


The Finalize in C# is used to free unmanaged resources like database connections etc. The method finalize() is for unmanaged resources.
