I have two objects, let's say person and address. I want to allow person
objects to have multiple addresses. What is the best way to accomplish
this? I would think to create a collection of address objects that is
exposed as a property of the person object. I'm thinking something like the
following:

Person _Person = null;
Address _Address = null;

_Person = new Person();
_Person.Name = "John Doe";
_Person.BirthDate = "11/10/1969";

_Address = new Address();
_Address.Street = "100 Main Street";
_Address.City = "Erie";
_Address.State = "IN";
_Address.Zip = "16889";

_Person.AddressList.Add(Address);

_Address = new Address();
_Address.Street = "1600 Pennsylvania Avenue";
_Address.City = "Washington";
_Address.State = "DC";
_Address.Zip = "20001";

_Person.AddressList.Add(Address);

_Person.Save();

Thanks in advance.

Jon

This is a good solution. What I would change is the constructor of your
classes:

public Address(String Street, String City, String State, String Zip)
{
    _Street = Street;
    _City = City;
    _State = State;
    _Zip = Zip;
}

_Adress = new Address("100 Main Street","Erie","IN","16889");

It saves you a couple of lines :-). You might consider doing the same for
the Person constructor

I agree with this approach too. What I normally do is create a few
overloaded constructors.

1 - one that accepts all of the values needed to create a new instance
of the object and set all of its values. I use this one to create a
brand new instance

    _Address = new Address("100 Main Street","Erie","IN","16889");

2 - another that accepts an id of some sort that corresponds to the
object's id in the database. I use this one to retreive an existing
object from the database.

    _Address = new Address(125);

3 - sometimes one that takes not property values but just creates an
empty instance (no property values set) - like your original version

    _Address = new Address();

My 2 cents
Michael

Now that we agree on that, let me get further into my question.

I have a person object, and an address object. These objects have
PersistanceManager objects that manage db work.

The address object accepts a ID for the user, and other address fields like
street, etc...

I also have an AddressList object that represents a collection of address
objects. The AddressList object only has 2 public properties (count and
add), and an internal member called ListOfAddresses (internal because I want
a method in the person object to be the only access point to the address
collection). This object is exposed via a property in the person object.

What I'm struggling with is where is the best place to put the code to check
the address collection, iterate through, and call the save command on the
address objects. In the PersistanceManager for Person ?

Obviously, I can do this directly if I want:

Address _Address = new Address();
_Address.User = 123; //User ID
_Address.Street = "100 Main Street";
_Address.City = "Erie";
_Address.State = "IN";
_Address.Zip = "16889";
_Address.Save();

However, the idea should be that the client simply adds address objects to
the collection - calling Person.Save() should update any addresses found in
the collection. I guess I'm answering my own question... are there any
objections so far?

Thanks.

Jon
