[設計模式練習]轉接器模式

2010-04-16

將程式設計人員分成資深和新進人員

有天公司來了外籍的工程師在外駐點

要讓他設計符合公司規範的產品

利用轉接器設計告知

用戶端程式碼


            DesignModelTest.轉接器.ITWorker old = new DesignModelTest.轉接器.OldITWorker("老鳥");
            old.Design();
            old.Maintain();
            DesignModelTest.轉接器.ITWorker newone = new DesignModelTest.轉接器.NewITWorker("小菜");
            newone.Design();
            newone.Maintain();
            //透過轉接器來執行物件內的動作即使彼此不認識
            DesignModelTest.轉接器.ITWorker foreign = new DesignModelTest.轉接器.Translator("老外");
            foreign.Design();
            foreign.Maintain();
            Console.Read();
