Strategy Pattern.
Tudo está encapsulado em classes que implementem a interface.Tivemos os mesmos resultados que antes, mas agora em um implementação totalmente diferente! In this article, I am going to discuss the Strategy Design Pattern in C# with examples.Please read our previous article where we discussed the Visitor Design Pattern in C# with real-time examples. The Strategy Design Pattern allows an object to have some or all of its behavior defined in terms of another object which follows a particular interface. Strategy - Free .NET Design Pattern C#. Mas temos uma solução para isso! Strategy is a behavioral design pattern that lets you define a family of algorithms, put each of them into a separate class, and make their objects interchangeable. Hooray! Instead of implementing a single algorithm directly, code receives run-time instructions as to which in a family of algorithms to use. Mas notaram que tivemos que deixar a lógica de négocio nessa classe? E o principal é que podemos garantir nossas lógicas todas por cenários de testes!Mas ainda não terminamos!
Tuttavia, gli algoritmi necessari allo svolgimento di una determinata operazione potrebbero variare nel tempo, rendendo necessaria la modifica della classe “Context” (o in alternativa, una sua sottoclasse che esegue l’overlo… Nella programmazione ad oggetti, lo strategy pattern è uno dei pattern fondamentali, definiti originariamente dalla Gang of Four. A Strategy Pattern says that "defines a family of functionality, encapsulate each one, and make them interchangeable". Strategy Design Pattern Class Diagram.

Strategy Design Pattern Important Points. It defines each behavior within its own class, eliminating the need for conditional statements.
The Strategy pattern is really about having a different implementation that accomplishes (basically) the same thing, so that one implementation can replace the other as the strategy requires.

Alcuni esempi sono:I pattern architetturali operano ad un livello diverso (e più ampio) rispetto ai design pattern, ed esprimono schemi di base per impostare l'organizzazione strutturale di un sistema software. Free source code and UML.
