What is the difference between Virtual method and Abstract method?
Câu trả lời What is the difference between Virtual method and Abstract method?
Here is the difference between virtual methods and abstract methods in C#:
Virtual Methods
Virtual methods are implemented in a base class and can be overridden in derived classes.
The base class implementation provides a default behavior that can be used if a derived class does not override the method.
If a derived class overrides a virtual method, it provides its own implementation that replaces the inherited implementation.
Virtual methods allow for polymorphism, where objects of a derived class can be treated as objects of the base class and the correct method is called at runtime based on the actual type of the object.
The virtual keyword is used to mark a method as virtual in the base class.
The override keyword is used to override a virtual method in a derived class.
Abstract Methods
Abstract methods are declared in an abstract base class but hav...
