I am very new to web application development. When I try and retrieve the orders made by customers. My web application gives out following errors.

Thanks in advance.

System.NullReferenceException : {"Object reference not set to an instance of an object."}

DATA : {System.Collections.ListDictionaryInternal}

Hresult : -2147467261

Helplink : Null

InnerException : Null

Object reference not set to an instance of an object.

{System.Web.Mvc.ActionResult Orders()}

  • Please share the code from the controller action. – akg179 Jun 03 '19 at 17:08
  • public ActionResult Orders() { List ordersForAdmin = new List(); using (Db db = new Db()) { List orders = db.Orders.ToArray().Select(x => new OrderVM(x)).ToList(); foreach (var order in orders) { Dictionary productsAndQty = new Dictionary(); int total = 0; List orderDetailsList = db.OrderDetails.Where(X => X.OrderId == order.OrderId).ToList(); UserDTO user = db.Users.Where(x => x.Id == order.UserId).FirstOrDefault(); string username = user.Username; – Niall Jun 03 '19 at 18:23
