Lambda expressions in C# are a concise and powerful way to write inline functions that can be used as delegates or functional interfaces. Lambda expressions allow you to write code that is more readable and maintainable by reducing the amount of boilerplate code required for creating delegates or functional interfaces. A lambda expression is an … Read more

Generics in C# are a powerful feature that allow you to write code that can be used with any data type. Generics make it possible to write reusable code that can work with different types of data without having to write separate code for each type. In C#, generics are implemented using type parameters. Type … Read more

In C#, delegates and events are two powerful features that allow you to implement the observer pattern, which allows an object to notify other objects when something interesting happens. Here are some of the key concepts related to delegates and events in C#: 1. Delegates: A delegate is a type that represents a reference to … Read more

In C#, interfaces and abstract classes are two ways to define contracts or blueprints for classes. They help to define a set of rules or guidelines that a class must follow, which makes it easier to write code that is flexible and maintainable. Here are some of the key concepts related to interfaces and abstract … Read more

In C#, inheritance and polymorphism are two fundamental concepts of object-oriented programming. Inheritance allows you to create a new class that is a modified version of an existing class, while polymorphism allows you to use objects of different classes in a unified way.
