Working with array

I am trying to create a class for serializing and deserializing arrays. The class I have created, appears to be working for deserializing, but when I try to serialize the array, I am having issues. I am a fairly new C# developer and I am sure I have left an important piece out of my code, I just am not sure what.

Below is a copy of the class I created:

namespace PinnacleCartFormAPI
    class clsGetCustomersResponse
        public Customer Customer = new Customer();//{ get; set; }

    public class Customer
        public Int32 UserId;
        public string UserName;
        public CustBilling Billing = new CustBilling();
        public AddressBook[] AddressBook;// AddressBook = new AddressBook();

    public class CustBilling
        public string FullName, FirstName, LastName, Email, Company, Phone;
        public CustAddress Address = new CustAddress();

    public class CustAddress
        public string Name, Street1, Street2, City, State, Zip, Country;

    public class AddressBook
        public string Name, Street1, Street2, City, State, Zip, Country;

As you can see, the AddressBook class needs to be an Array. I believe my issue is related to the fact that I am not initiating the AddressBook class properly as an array.

Below, is a copy of the calling code that adds values to the different elements of the class:

clsGetCustomersResponse GetCustomersResp = new clsGetCustomersResponse();
GetCustomersResp.Customer.UserId = 123456;
GetCustomersResp.Customer.UserName = "Username";
GetCustomersResp.Customer.Billing.FullName = "Full Name";
GetCustomersResp.Customer.Billing.FirstName = "First Name";
GetCustomersResp.Customer.Billing.LastName = "Last Name";
GetCustomersResp.Customer.Billing.Email = "";
GetCustomersResp.Customer.Billing.Phone = "7778889999";
GetCustomersResp.Customer.Billing.Address.Name = "Address Name";
GetCustomersResp.Customer.Billing.Address.Street1 = "Address Street 1";
GetCustomersResp.Customer.Billing.Address.Street2 = "";
GetCustomersResp.Customer.Billing.Address.City = "Address City";
GetCustomersResp.Customer.Billing.Address.State = "Address State";
GetCustomersResp.Customer.Billing.Address.Zip = "Address Zip";
GetCustomersResp.Customer.Billing.Address.Country = "Address Country";
GetCustomersResp.Customer.AddressBook[0].Name = "Address Name";
GetCustomersResp.Customer.AddressBook[0].Street1 = "Address Street 1";
GetCustomersResp.Customer.AddressBook[0].Street2 = "";
GetCustomersResp.Customer.AddressBook[0].City = "Address City";
GetCustomersResp.Customer.AddressBook[0].State = "Address State";
GetCustomersResp.Customer.AddressBook[0].Zip = "Address Zip";
GetCustomersResp.Customer.AddressBook[0].Country = "Address Country";


As soon as I hit the bolded lines, I receive the following error:

"Object reference not set to an instance of an object"

Again, I believe this is a result of me not properly initializing the AddressBook portion of the code. However, I am not certain how to do that with the array.

Can you please provide me with some direction on this?

Is there anyone in the JSON.NET interwebz that is able to offer me some assistance on this issue? I am sure it is a simple fix, but I am new to C# and especially JSON.NET.

GetCustomersResp.Customer.AddressBook = new AdressBook[1];

Basically, your poperty GetCustomersResp.Customer.AddressBook is null...
