All classes (except static classes) can be inherited from unless you mark them with the 'sealed' keyword: public sealed class MyClass // can't inherit from this class { // code } If a child class contains a method which overrides a virtual method in its base class you can prevent further overriding by descendants of the child class by marking the method as 'sealed'.
