Question

What are the pros and cons of using Primitve Types or Complex Types?

When should you use primitive types over complex types and vice versa?

i.e.:

public class Person
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public int Age { get; set; }
    public int IQ { get; set; }
}


public void FooPrimitiveTypes (string firstName, string lastName, int age, int IQ)
{

}

public void FooComplexTypes(Person person)
{

}

Answer 1

1. To pass each property separately are generally used when you are dealing with disjoint values. Also, sometimes used on constructors. Bad practice.

2. This way is preferred when the values are related.

Why #1 is a bad practice – suppose you needed to add height. I’d much rather update one class by adding another property, instead of 50 methods.
