We might want two instances of a person to be able to procreate. We could do this with the following method:
// method to "multiply"
public Person Procreate(Person partner)
{
var baby = new Person("Baby");
Children.Add(baby);
partner.Children.Add(baby);
return baby;
}Now, we can get two people to make a baby:
var harry = new Person { Name = "Harry" };
var mary = new Person { Name = "Mary" };
var baby1 = harry.Procreate(mary);
WriteLine($"{mary.Name} has {mary.Children.Count} children.");
WriteLine($"{harry.Name} has {harry.Children.Count} children.");Run the application and view the output:
Mary has 1 children. Harry has 1 children.
An alternative would be to define an operator to allow two people to "multiply". To allow this, we need to define a static operator for the * symbol:
// operator to "multiply"
public static Person operator *(Person p1, Person p2)
{
return p1.Procreate(p2);
}Add the following code at the end of the Main method...
