Accessing data from list C# that stores deserialized XML

this is my Xml file that I am trying to desirialize:

<?xml version="1.0"?>
<AddressDirectory>
  <Address>
    <HouseNo>1</HouseNo>
    <StreetName>Pitampura</StreetName>
    <City>Delhi</City>
  </Address>
  <Address>
    <HouseNo>4</HouseNo>
    <StreetName>Rohini</StreetName>
    <City>Delhi</City>
  </Address>
</AddressDirectory>

these are my classes:

public class AddressDirectory
{
    [XmlElement("Address")] 
    public List<Address> addressList = new List<Address>(); 
}
public class Address
{
    public int HouseNo { get; set; }
    public string StreetName { get; set; }
    public string City { get; set; }
}

this is my main:

XmlSerializer deserializer = new XmlSerializer(typeof(AddressDirectory));
TextReader reader = new StreamReader(@"D:\myXml.xml");
object obj = deserializer.Deserialize(reader);
AddressDirectory XmlData = (AddressDirectory)obj;
reader.Close();

this is how I access the elements that must have ben saved in the list:

XmlData.addressList[0].HouseNo;
XmlData.addressList[0].StreetName; 
XmlData.addressList[0].City;

or in a loop I access like this:

for (int i = 1; i < 10; i++)
            {
                Console.Write("house number for {0}: ", i);
                Console.WriteLine(XmlData.addressList[i].HouseNo);
                Console.Write("Street Name  for {0}: ", i);
                Console.WriteLine(XmlData.addressList[i].StreetName);
                Console.Write("City         for {0}: ", i);
                Console.WriteLine(XmlData.addressList[i].City);
            }

this is the error that I am getting when I execute the program:

Index was out of range. Must be non-negative and less than the size of the collection.

I guess this is because we are not adding anything in the list. Because to add to the list we have to use List.Add() somewhere in the main.
