软件设计模式C#

Software Design Patterns in C#

 

设计模式（Design Patterns）是你在实际应用程序开发中，对不断发现的软件设计问题的重复解决方案。设计模式是关于对象的设计和交互，关于对经常出现的软件开发挑战的一些完美和重用的解决方案，也提供了一个交流平台，

 

“四人帮”（GOF）模式被认为是所有其他模式的基础，23种设计模式分为3类：创建型模式（Creational Pattern），结构型模式（Structural Pattern）和行为型模式（Behavioral Pattern）。

 

为了让你先起步，这里提供了2种形式的源码：结构方面的（structural）和现实应用方法的（real-world）。结构方面的代码使用模式定义和UML类图中提供的类型名称，而实际应用方面的代码提供了你需要使用模式的真实设计情况。

 

Creational Patterns 创建型模式
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 结构型模式
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 行为型模式
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
