ASP.Net: Create Business Class for nested data using C# and VB.Net

Hi ramco1917,

I am working on it, I will get back to you soon.

Code

C#

protected void Page_Load(object sender, EventArgs e)
{
    Order order = new Order();
    order.OrderNo = 1;
    order.OrderDate = DateTime.Now;

    Root root = new Root();
    root.Order = order;
    root.OrderDetails = GetListOfStudents();
}

public List<OrderDetail> GetListOfStudents()
{
    List<OrderDetail> orderDetails = new List<OrderDetail>();
    orderDetails.Add(new OrderDetail
    {
        OrderNo = 1,
        ItemCode = "012",
        Amount = "5000"
    });
    orderDetails.Add(new OrderDetail
    {
        OrderNo = 1,
        ItemCode = "013",
        Amount = "4000"
    });
    return orderDetails;
}

public class Root
{
    public Order Order { get; set; }
    public List<OrderDetail> OrderDetails { get; set; }
}

public class Order
{
    public int OrderNo { get; set; }
    public DateTime OrderDate { get; set; }
}

public class OrderDetail
{
    public int OrderNo { get; set; }
    public string ItemCode { get; set; }
    public string Amount { get; set; }
}

VB.Net

Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load
    Dim order As Order = New Order()
    order.OrderNo = 1
    order.OrderDate = DateTime.Now
    Dim root As Root = New Root()
    root.Order = order
    root.OrderDetails = GetListOfStudents()
End Sub

Public Function GetListOfStudents() As List(Of OrderDetail)
    Dim orderDetails As List(Of OrderDetail) = New List(Of OrderDetail)()
    orderDetails.Add(New OrderDetail With {
        .OrderNo = 1,
        .ItemCode = "012",
        .Amount = "5000"
    })
    orderDetails.Add(New OrderDetail With {
        .OrderNo = 1,
        .ItemCode = "013",
        .Amount = "4000"
    })
    Return orderDetails
End Function

Public Class Root
    Public Property Order As Order
    Public Property OrderDetails As List(Of OrderDetail)
End Class

Public Class Order
    Public Property OrderNo As Integer
    Public Property OrderDate As DateTime
End Class

Public Class OrderDetail
    Public Property OrderNo As Integer
    Public Property ItemCode As String
    Public Property Amount As String
End Class
