interface IMethods { void F(); void G(); } abstract class C: IMethods { public abstract void F(); public abstract void G(); }Here, the implementation of IMethods maps F and G onto abstract methods, which must be overridden in non-abstract classes that derive from C. end example] Paragraph 21 Note that explicit interface member implementations cannot be abstract, but explicit interface member implementations are of course permitted to call abstract methods. [Example: For example
interface IMethods { void F(); void G(); } abstract class C: IMethods { void IMethods.F() { FF(); } void IMethods.G() { GG(); } protected abstract void FF(); protected abstract void GG(); }Here, non-abstract classes that derive from C would be required to override FF and GG, thus providing the actual implementation of IMethods. end example]
