How to do Method hiding in C# Programming

Can you help me to buy a coffee:
https://www.buymeacoffee.com/coffeeprogram namespace FistConsoleProject;

//base class
public class Employee
{
public string FirstName;
public string LastName;

public void PrintFullName()
{
Console.WriteLine(FirstName + " " + LastName); //now this method is discarded in derived classes
}
}
//child class or derived class
public class FullTimeEmployee : Employee
{

public new void PrintFullName()
{
base.PrintFullName();
Console.WriteLine(FirstName + " " + LastName + " - Full Time");
}
}
//this is also a child class
public class PartTimeEmployee : Employee
{
public new void PrintFullName()
{
base.PrintFullName();
Console.WriteLine(FirstName + " " + LastName + " - Part Time");
}
}
//now how we can access base class method in derived class?
