Answer 1

When a derived class contains a method or property that overrides a parent class method or property, you might have occasion to use the parent class version within the subclass. If so, you can use the keyword base to access the parent class method or property. For example:
class CommissionEmployee : Employee
{
new public string GetGreeting()
{
string greeting = base.GetGreeting();
greeting += "\nI work on commission.";
return greeting;
}
}
