yse virtual method in csharp

In C#, a virtual method is a method that can be overridden in subclasses. It allows for polymorphism, as a subclass can have its own implementation of the method while still being called through the base class.

To use a virtual method in C#, you need to declare the method as virtual in the base class:

main.cs
public class Animal
{
    public virtual void MakeSound()
    {
        Console.WriteLine("The animal makes a sound");
    }
}

8 lines

Then, in the derived class, you can override the method using the override keyword:

main.cs
public class Dog : Animal
{
    public override void MakeSound()
    {
        Console.WriteLine("Woof!");
    }
}
115 chars
8 lines

When you call MakeSound() on a Dog object, the overridden method in the Dog class is called instead of the base class implementation:

main.cs
Animal myAnimal = new Dog();
myAnimal.MakeSound(); // Outputs "Woof!"

This allows for flexibility in object-oriented programming, as you can use a base class to define a common behavior across objects, while still allowing for specific implementation in subclasses.
