Base Classes in C#
Inheritance Hierarchy:
A base class serves as the foundation for derived (child) classes, allowing the sharing of common functionality.
Derived classes inherit members (fields, methods, properties) from their base class.
// Base class
public class Vehicle
{
public void Start()
{
Console.WriteLine(“Engine starting…”);
}
public void Stop()
{
Console.WriteLine(“Engine stopping…”);
}
}
// Derived class inheriting from Vehicle
public class Car : Vehicle
{
// Additional members specific to Car
}
Using the base Keyword:
The base keyword allows you to call members from the base class within a derived class.
public class FlyingVehicle : Vehicle
{
public void Fly()
{
base.Start(); // Calling the Start method from the base class
Console.WriteLine(“Taking off…”);
}
}
Creating Instances:
You can create instances of derived classes and access both base and derived class members.
Car myCar = new Car();
myCar.Start(); // Calls the Start method from the base class
myCar.Stop(); // Calls the Stop method from the base class
Extending Functionality:
Derived classes can extend or override the functionality of the base class.
{
// Override the Start method to provide electric car-specific behavior
public override void Start()
{
Console.WriteLine(“Initializing electric motor…”);
base.Start(); // Call the Start method from the base class
}
}
