Simple data type question. namespace name 'Address' could not befound?

[karen.homersham]

Just working through Apress Pro ASP NET.2.0.E Commerce in C Sharp. I
am having problems compiling the following:

using System;
using System.Collections.Generic;
using System.Text;

namespace ECommerce.Common
{
public class Users
{
private int _addressid;
private Address _address;

public Address Address
{
get { return _address; }
set { _address = value; }
}

public int AddressID
{
get { return _addressid; }
set { _addressid = value; }
}
}
}

Address is not a built in datatype and has not been defined anywhere
previously. The book doesn't mention anything about the Address field
and I don't understand well enough to read between the lines.

If someone could put me in the right direction, I would be greatly
appreciative.

Thanks in advanced
Karen

No, Address is not a primitive type of of int, long, string, double, or
decimal etc, etc.

It's an obvious error in the declaration of the variable in the book, which
happens all the time.

I suspect that string _address is what is needed there.

It is pure guesswork to try and say what the author intended.

Maybe there should be an Address class and it is just not in the book,
because it is not important for the point.

Maybe the type should be string.

BTW, I would be very surprised if this is the final version of the
User class. It looks very weird to me. A user with only address id and
address as attributes ?? (and why is address id not part of address ??)

I adapted the code as a working example, here is original.

using System;
using System.Collections.Generic;
using System.Text;

namespace LittleItalyVineyard.Common
{
public class EndUser
{
private int _enduserid;
private int _endusertypeid;
private string _firstname;
private string _lastname;
private Address _address;
private int _addressid;
private ContactInformation _contactinformation;
private int _contactinformationid;
private string _password;
private bool _issubscribed;

public EndUser()
{
_address = new Address();
_contactinformation = new ContactInformation();
}

public int EndUserID
{
get { return _enduserid; }
set { _enduserid = value; }
}

public int EndUserTypeID
{
get { return _endusertypeid; }
set { _endusertypeid = value; }
}

public string FirstName
{
get { return _firstname; }
set { _firstname = value; }
}

public string LastName
{
get { return _lastname; }
set { _lastname = value; }
}

public Address Address
{
get { return _address; }
set { _address = value; }
}

public int AddressID
{
get { return _addressid; }
set { _addressid = value; }
}

public ContactInformation ContactInformation
{
get { return _contactinformation; }
set { _contactinformation = value; }
}

public int ContactInformationID
{
get { return _contactinformationid; }
set { _contactinformationid = value; }
}

public string Password
{
get { return _password; }
set { _password = value; }
}

public bool IsSubscribed
{
get { return _issubscribed; }
set { _issubscribed = value; }
}
}
}
From what I gather ContactInformation, Address and EndUserTypeID, are
1 to many relationships. EnduserTypeID is only got 2 fields id and
name. Address and ContactInformation have lots of fields. Was
wondering if I would have to complete Data Access stuff before this
would work?
If I compile original code it works fine. I don't really want to go
on any further if I don't uderstand this as I may get deeper into a
hole.

Found the problem I had to complete the address class first. I was
compiling as I went just to check to see if each class was right, but
a bit too fast. I uderstand what is going on better though.

Thanks guys
