The Composite pattern in C#

  Hello, fellow C# developers!  Today, I will write a short article about the composite pattern.  The composite pattern is a structural design pattern that allows you to compose objects into tree structures and then work with these structures as if they were individual objects. The composite pattern is useful when you need to represent part-whole hierarchies of objects, such as files and folders, GUI components, or organizational charts.  😎 The composite pattern consists of three main components: Component : This is an abstract class or an interface that defines the common operations for all the objects in the hierarchy. It can also define some default behavior for common methods. Leaf : This is a class that implements the component interface and represents the primitive objects that cannot be further divided. For example, a file is a leaf in a file system hierarchy. πŸ“„ Composite : This is a class that implements the component interface and represents the complex ob...

Bridge pattern in C#

  Hello, C# enthusiasts! 😍 Today, I want to share with you a very useful design pattern that can help you separate the business logic from the data access layer in your applications. This pattern is called the Bridge pattern, and it is one of the structural design patterns that deal with how classes and objects are composed to form larger structures. πŸ—️ The Bridge pattern allows you to decouple an abstraction (such as an interface or an abstract class) from its implementation (such as a concrete class that implements the interface or inherits from the abstract class) so that the two can vary independently. This means that you can change the data access layer without affecting the business logic layer, and vice versa. πŸ™Œ But why would you want to do that? Well, there are many scenarios where you might have more than one version of an abstraction, or more than one way of implementing an abstraction. For example, suppose you are developing a financial application that needs to perfo...

Proxy pattern in C#

Hi! Today, I’m going to talk about the Proxy pattern and how it can be used in C# 😊. The Proxy pattern is a structural design pattern that provides a surrogate or placeholder for another object. A proxy controls access to the original object, allowing you to perform something either before or after the request gets through to the original object. Why would you want to use a proxy? Well, there are several reasons, such as: Lazy initialization : You can create a proxy to delay the creation of a heavy object until it’s actually needed. Remote access : You can create a proxy to represent a remote object and handle network communication behind the scenes. Access control : You can create a proxy to check the permissions of clients before allowing them to access the original object. Logging : You can create a proxy to log the requests and responses of the original object. In C#, you can implement the Proxy pattern by creating an interface that defines the common methods for both the original...
