Setting up an API Test Framework

I’m testing an API and I’m looking to define my payload using classes so that my program can then deserialize/serialize into any format (namely XML in my case). Below is an example of the payload:

<Order>
<BillingAddress>
<AddressLine1></AddressLine1>
<AddressLine2></AddressLine2>
<City></City>
</BillingAddress>
<Items>
<Item IsKit=”false”>
<CountryVATRate></CountryVATRate>
<Group></Group>
<Reference></Reference>
</Item>
<Item IsKit=”false”>
<CountryVATRate>0.25</CountryVATRate>
<Group>5360693120</Group>
<Reference>5360693120</Reference>
</Item>
</Items>
<OrderAmount>35</OrderAmount>
<TimeStamp>2017-03-30 00:00:00.102</TimeStamp>
</Order>

So my thinking is that I would have an overall Order class which looks something like the below

public class Order()
{
BillingAddress bAddr; //another class
List Items;
double OrderAmount;
DateTime TimeStamp;
}

What I am trying to work out is the best way of setting up my framework so that in the example of the BillingAddress class I can set up a series of properties e.g. AddressLine1/AddressLine1 etc which can then be called when I run the test

Any advice on how to structure the test framework would be most appreciated
