Design Patterns (.NET C#)

Design Patterns

Creational Patterns

• Singleton - A class of which only a single instance can exist
  • Singleton (not thread safe)
  • Singleton (thread safe - .NET 4 Lazy T type)

Factory Method

• Creates an instance of several derived classes

Structural Patterns

Adapter

• Adapter is a structural design pattern, which allows incompatible objects to collaborate.

Decorator

• Add responsibilities to objects dynamically.

Behavioral Patterns

Template Method

• Defines the skeleton of an algorithm in the superclass but lets subclasses override specific steps of the algorithm without changing its structure.

State

• Allow an object to alter its behavior when its internal state changes. The object will appear to change its class.
