C# Programming/Keywords/abstract

Abstract classes may contain abstract members in addition to implemented ones. That is, while some of the methods and properties in an abstract class may be implemented, others (the abstract members) may have their signatures defined, but have no implementation. Concrete subclasses derived from an abstract class define those methods and properties.
