You are implementing an ASP.NET Web site. The site contains the following class.
public class Address
{
public int AddressType;
public string Line1;
public string Line2;
public string City;
public string ZipPostalCode;
}
The Web site interacts with an external data service that requires Address instances to be given in the following XML format.
<Address AddressType=”2″>
<Line1>250 Race Court</Line1>
<City>Chicago</City>
<PostalCode>60603</PostalCode>
</Address>
You need to ensure that Address instances that are serialized by the XmlSerializer class meet the XML format requirements of the external data service.

A.
Add the following attribute to the AddressType field.
