Software Design Patterns in C#

軟體設計模式C#

Software Design Patterns in C#

設計模式（Design Patterns）是你在實際應用程式開發中，對不斷發現的軟體設計問題的重複解決方案。設計模式是關于對象的設計和互動，關于對經常出現的軟體開發挑戰的一些完美和重用的解決方案，也提供了一個交流平台，

“四人幫”（GOF）模式被認為是所有其他模式的基礎，23種設計模式分為3類：建立型模式（Creational Pattern），結構型模式（Structural Pattern）和行為型模式（Behavioral Pattern）。

為了讓你先起步，這裡提供了2種形式的源碼：結構方面的（structural）和現實應用方法的（real-world）。結構方面的代碼使用模式定義和UML類圖中提供的類型名稱，而實際應用方面的代碼提供了你需要使用模式的真實設計情況。

Creational Patterns 建立型模式
Abstract Factory	Creates an instance of several families of classes
Builder	Separates object construction from its representation
Factory Method	Creates an instance of several derived classes
Prototype	A fully initialized instance to be copied or cloned
Singleton	A class of which only a single instance can exist

Structural Patterns 結構型模式
Adapter	Match interfaces of different classes
Bridge	Separates an object’s interface from its implementation
Composite	A tree structure of simple and composite objects
Decorator	Add responsibilities to objects dynamically
Façade	A single class that represents an entire subsystem
Flyweight	A fine-grained instance used for efficient sharing
Proxy	An object representing another object

Behavioral Patterns 行為型模式
Chain of Resp.	A way of passing a request between a chain of objects
Command	Encapsulate a command request as an object
Interpreter	A way to include language elements in a program
Iterator	Sequentially access the elements of a collection
Mediator	Defines simplified communication between classes
Memento	Capture and restore an object's internal state
Observer	A way of notifying change to a number of classes
State	Alter an object's behavior when its state changes
Strategy	Encapsulates an algorithm inside a class
Template Method	Defer the exact steps of an algorithm to a subclass
Visitor	Defines a new operation to a class without change
