Error: does not contain constructor with 0 arg issues. Can someone help me out?

[Michael Tristan]

I'm not sure what I am doing wrong, but I am trying to create a new object and it gives me the error that it does not contain a constructor with 0 arguments. I understand that the way I am writing it causes it to appear like it's parameterless, but I do not know how to fix it. The ultimate goal is to create a series of orders that will display to the screen with the details. I only have one order information set up, Ben Franklin's order, but intend on having more. Here is my code:

 public class Order
    {
        private int orderNum;
        private string custName;
        private int quantOrdered;
        private int totalPrice;
        private double price = 19.95;
 
        public Order(int ordNum, string name, int quantity)
        {
            OrderNum = ordNum;
            CustName = name;
            QuantOrdered = quantity;
        }
public override string ToString()
        {
            return ("Order Number: " + OrderNum + "Customer Name: " + CustName + "Quantity Ordered: " + QuantOrdered + "Total Price: " + TotalPrice.ToString("C"));
        }
 
 
        public int OrderNum{get; set;}
        public string CustName { get; set; }
        public int QuantOrdered
        {
            get
            {
                return quantOrdered;
            }
            set
            {
                quantOrdered = value;
                totalPrice = Convert.ToInt32(quantOrdered) * Convert.ToInt32 (price);
            }
        }
        public int TotalPrice
        {
            get
            {
                return totalPrice;
            }
        }
 
           public static void Main()
           {
 
               Order aOrder = new Order();
               aOrder.OrderNum = 1;
               aOrder.CustName = "Franklin, Benjamin";
               aOrder.QuantOrdered = 6;
               Console.WriteLine("Order information: {0}", aOrder);
           }
 
 
    }
}
 

The error message states: Error 1 'OrderDemo.Order' does not contain a constructor that takes '0' arguments

I figured it out. I declared the parameters like this:

 public static void Main()
           {
 
               Order aOrder = new Order(1, "Franklin, Benjamin", 6);
               Order aOrder2 = new Order(2, "Jefferson, Thomas", 4);
               Console.WriteLine("Order information:\n {0}\n{1}", aOrder, aOrder2);
           }
