virtual methods

Question

If I have a class named \"Parent\" for example. he has a method named \"Print\". the class \"Kid\" is derived, it has a method named

Answer 1

A virtual method call uses the actual type of the object to determine which method to call, while a non-virtual method uses the type of the reference.

Say that you have:

public class Parent {
  public void NonVirtualPrint() {}
  public virtual void VirtualPrint() {}
}

public class Kid : Parent {
  public new void NonVirtualPrint() {}
  override public void VirtualPrint() {}
}

Then:

Parent p = new Parent();
Parent x = new Kid();
Kid k = new Kid();

p.NonVirtualPrint(); // calls the method in Parent
p.VirtualPrint(); // calls the method in Parent

x.NonVirtualPrint(); // calls the method in Parent
x.VirtualPrint(); // calls the method in Kid

k.NonVirtualPrint(); // calls the method in Kid
k.VirtualPrint(); // calls the method in Kid
