Master Detail using POCOs

• We want to include in Details of the Order in our Xml.
• Add an OrderDetailPoco class
• Add a Details field to the OrderPoco class

namespace Northwind.Training.PocosAndXml
{
    public class OrderPoco
    {
        public int OrderID;
        public string CustomerID;
        public int Shipper;
        public List<OrderDetailsPoco> Details = new List<OrderDetailsPoco>();
    }
    public class OrderDetailsPoco
    {
        public int ProductID;
        public decimal Quantity;
        public decimal UnitPrice;
    }
} 

• Adding the Order Details data from code

 private void DemoWriteXml()
{
    var o = new OrderPoco
    {
        OrderID = 1,
        CustomerID = "ABCDE",
        Shipper = 5
    };
    o.Details.Add(new OrderDetailsPoco {
        ProductID = 1,
        Quantity = 3,
        UnitPrice = 10.5m
    });
    o.Details.Add(new OrderDetailsPoco
    {
        ProductID = 2,
        Quantity =73,
        UnitPrice = 55
    });
    SaveXml(o, @"c:\temp\orders.xml");
}
