コード検査: 冗長な「抽象」修飾子

interface IBase { public void Foo() { Console.WriteLine("default implementation"); } } class DerivedFromBase : IBase { // no need to override 'Foo' since it has a default implementation } interface IAbstract : IBase { // Implementation without a body cancels the default implementation // in the base interface and has to be 'abstract' abstract void IBase.Foo(); // 'abstract' is redundant because this member is abstract anyway abstract void Bar(); } class DerivedFromAbstract : IAbstract { // Default implementation of 'Foo()' is cancelled // with 'abstract void IBase.M' in 'IAbstract' // therefore we have to provide an implementation here and // cannot use the default implementation from 'IBase' public void Foo() { Console.WriteLine("some implementation"); } // 'Bar' doesn't have a body in the base interface, // therefore we have to provide an implementation anyway public void Bar() { Console.WriteLine("some implementation"); } }
