The document outlines design patterns in C#, categorizing them into three main types: creational patterns focus on object creation, structural patterns emphasize the organization of classes and objects, and interaction patterns detail how objects communicate. Examples of each category include the singleton, adapter, and observer patterns. The article aims to elevate coding standards by exploring these advanced design principles and methodologies.

1. Mastering the Craft: Types of Patterns in C#
C# offers a robust set of resources for developing dependable and efficient software programs.
Yet, another level of design principles and methodologies exists that extend past the fundamental
syntax, potentially elevating your code to a higher standard. In this article, we'll delve into the
realm of C# design solutions and analyze the well-known design patterns.
There are three main categories of design patterns in C#:
1. Creational Patterns: These patterns concentrate on the creation of objects, offering ways
to separate the process of creating objects from their usage. Typical instances involve:
● Singleton: This guarantees that a class can only have one instance and offers a
worldwide entry point for it.
● Factory Method: Produces objects without revealing how they are made to the
code that uses them.
● Builder: Divides the task of building a complicated object from its display.
2. Class and Object Structures: These structures focus on how classes and objects are
organized, outlining the process of combining classes and objects to create more complex
structures. Examples are:
● Adapter: Enables different interfaces to work together.
● Facade: Offers an easier-to-use interface to a complicated system.
● Composite: Views a collection of objects as a unified entity.
3. Interaction Patterns: These patterns specify how objects communicate with each other
and their interactions. Examples are:
● Observer: Permits an object to inform other objects about changes in its condition.
● Strategy: Facilitates the selection of an algorithm at the moment of execution.
● State: Permits an object to change its behavior in response to changes in its internal
state.
