- What is encapsulation in C# and why is it important?
- Encapsulation is a principle of object-oriented programming that involves bundling data and methods together within a class.
- It helps in achieving data hiding, as the internal implementation details are hidden from external access.
- Encapsulation promotes modularity, code maintainability, and protects the integrity of data by providing controlled access through properties and methods.
- What are interfaces in C# and how are they used?
- Interfaces define a contract of methods, properties, and events that a class must implement.
- They provide a way to achieve multiple inheritance-like behavior in C#.
- By implementing interfaces, classes can ensure consistent behavior across different objects that share common functionality.
- Interfaces promote code abstraction, flexibility, and facilitate loose coupling between components.
- What is polymorphism in C# and how does it work?
- Polymorphism is a concept that allows objects of different types to be treated as instances of a common base type.
- It enables flexibility and extensibility in code by allowing methods to be overridden in derived classes.
- Polymorphism allows for runtime method binding, where the appropriate method implementation is determined based on the actual type of the object.
- It promotes code reusability, modularity, and supports the "open-closed" principle.
