Description: A virtual member in C# is a concept that allows defining a member of a class that can be overridden in derived classes. This means that, although the virtual member has an implementation in the base class, it can be modified in any class that inherits from it. This mechanism is fundamental in object-oriented programming, as it promotes code reuse and flexibility in implementing specific behaviors in derived classes. Virtual members are declared using the ‘virtual’ keyword in the base class and are overridden in the derived class using the ‘override’ keyword. This feature allows developers to create more complex and adaptable class hierarchies, where derived classes can customize or extend the behavior of their base classes. Additionally, virtual members are essential for implementing polymorphism, allowing a base class reference to point to a derived class object and execute the corresponding overridden method. In summary, virtual members are a powerful tool in C# that facilitates the creation of more dynamic and maintainable applications.
