Design Patterns - Using the State Pattern in C#

What is the State Pattern?

The State Pattern is a behavioral pattern that can be used to alter the behavior of an object at run time. As the state of an object changes, the functionality of the object can change drastically. This change of behavior is hidden from the Client and the Client interfaces with a wrapper object known as the Context. The State Pattern is a dynamic version of the Strategy Pattern.

Design Patterns: Simplify Distributed System Design Using the Command Pattern, MSMQ, and .NET


Service-oriented architecture is a great framework when you need to perform distributed computing tasks over the Internet. But when you want to perform processing inside your local network, a different solution may provide a better fit. That solution, based on the Command pattern, uses Windows services and Microsoft Message Queuing to implement a queued system that meets your needs better than a service-oriented solution. This article explains how to build it.

Prototype Design Pattern in C#. Vb.NET

Specify the kind of objects to create using a prototypical instance, and create new objects by copying this prototype

Adapter Design Pattern in C#, VB.NET

Convert the interface of a class into another interface clients expect. Adapter lets classes work together that couldn't otherwise because of incompatible interfaces.

Singleton Design Pattern in C#, Vb.NET

Ensure a class has only one instance and provide a global point of access to it.

Solidify Your C# Application Architecture with Design Patterns

design pattern can solve many problems by providing a framework for building an application. Design patterns, which make the design process cleaner and more efficient, are especially well-suited for use in C# development because it is an object-oriented language. Existing design patterns make good templates for your objects, allowing you to build software faster. This article describes several popular design patterns you can use in your own applications, including the singleton, the decorator, the composite, and the state classes, which can improve the extensibility of your applications and the reuse of your objects.

What Are Design Patterns and Do I Need Them?

Software professionals may be familiar with the term "Design Patterns," but many have no idea of where they come from and what they truly are. Consequently, some do not see the value and benefits design patterns bring to the software development process, especially in the areas of maintenance and code reuse.

Design Patterns for .NET

It is not the intent of the Design Pattern Series to focus on providing a theoretical knowledge dump of all there is to know about design patterns. There are many books that do that already. Instead, this series will focus on providing lots of practical examples. However, there will be some theory to help address important points concerning design patterns. I use the theory of design patterns mostly as a guide and instead make references to good design pattern books for more detail explanation.

Singleton Design Pattern in Asp.net using C#

When we want to make a only one instance of a class and also making sure that there is a global access point to that object then the design pattern we user is called Singleton. The pattern ensures that the class is instantiated only once and that all requests are directed to that one and only object.

The Factory Design Pattern

Software architects generally think in terms of high-level abstractions rather than low-level programming details. Representing a system in terms of high-level abstractions promotes understanding of the system and reduces its perceived complexity. One such set of abstractions is software design patterns. They have been successfully applied in the past to simplify and solve recurring problems in software design.

Abstract Factory Design Pattern (Sample in C# and VB .NET)

An abstract factory provides an interface for creating families of related objects without specifying their concrete classes. Sometimes one wants to construct an instance of one of a suite of classes, deciding between the classes at the time of instantiation. In order to avoid duplicating the decision making everywhere an instance is created, we need a mechanism for creating instances of related classes without necessarily knowing which will be instantiated.

Prototype Pattern-Creational Patterns in C#

The Prototype Pattern approaches the creation of the objects that our client will use by cloning instances from prototypes as required. This achieves the general aim of decoupling the client from the objects that it will use, but also adds some advantages unique to the Prototype pattern.

Abstract Factory Pattern-Creational Patterns

The Factory pattern allowed us to decouple our client from an object which it uses. The Abstract Factory pattern extends this idea to manage separate families of objects.

A runtime selection, or configuration option, in our client could decide which family of objects is to be used. The Abstract Factory pattern allows us to write generic code to instantiate and use the family objects regardless of which family is chosen at runtime. The pattern also helps us enforce a rule where objects from just the chosen family are used uniformly by the client.

GOF Creational Design Patterns with C#

The GOF design patterns help address the following challenges :

design ready to accommodate change & growth

design flexible systems which come ready to handle reconfiguration and run time tailoring

code in manner to facilitate reuse during the development and extension phases ... ie. both external and internal reuse, so that we are rewarded by efficiencies as the project progresses, coming from investments made earlier in the project.

implement change in a way that doesn't overly shorten the system's useful lifespan

Singleton Pattern-Creational Patterns

The Singleton pattern is a specialist creational pattern as it's primary focus is to facilitate a single shared instance of our object rather than to decouple our client from the object's implementation as with the other creational patterns.
