    public decimal Id { get; set; }
    public decimal customerId { get; set; }
    public string payment_method { get; set; }
    public string payment_status { get; set; }
    public double total_price { get; set; }
    public string date { get; set; }
    public List<OrderDetail> OrderDetails { get; set; }

    public decimal product_id { get; set; }
    public string product_name { get; set; }
    public double price { get; set; }
    public double quantity { get; set; }

    public string address { get; set; }
    public string city { get; set; }
    public string state_province { get; set; }
    public string postal_code { get; set; }
    public string country { get; set; }
    public string telephone { get; set; }

}

here is my model some of my API. using whole model like orderAdd, orderDetail. But, for order listing I want few fields from Order Model e.g Id, total_price, date and exclude rest of the fields and list in Web API response.

below is my response code

[ResponseType(typeof(List<Order>))]
[HttpGet, Route("api/Orders/getOrderList")]
public IHttpActionResult getOrderLists(decimal customerId, int limit = 3)
{
    List<Order> Model = new List<Order>();
    var orders = db.OrderMasters.Where(p => p.CustomerId == customerId).Take(limit);
    foreach (var o in orders)
    {
        Order O = new Order();
        O.Id = o.OrderId;
        O.date = o.PurchasedOn;
        O.total_price = o.Total;
        Model.Add(O);
    }

    return Ok(Model);
}
