how can i prevent overriding/hiding a base class method

[Guest]

Hi,

how can i prevent from a derive class to override/hide a base class method ?
because in c# there is the new keyword on a method.
i am looking for the same functionality as the 'final' keyword in java.

Thanks.

Use the Sealed Keyword.

If you do not mark a method as "virtual," it can not be overridden by an
inherited class. However, the inherited class may re-define the method by
using the "new" keyword. Unfortunately, this is not something that can be
overcome with C#. You may find the following reference useful:

Use the Sealed Keyword.

Agreed that that stops the use of override, but it doesn't stop somone using
new - and nothing can
