如何将 object 传递给它自己的函数之一？

Question

Let's say I have the following:

    public class Order
    {
        public string orderNumber { get; set; }
        public string customerName { get; set; }
        public bool isRewardsMember { get; set; }
        public string transactionNumber { get; set; }
        public List<Guid> cart { get; set; }
        public CouponResponse GeneratedCoupons = GenerateCoupons(this); <--- How could I do this?
        
        
        public CouponResponse GenerateCoupons(Order order)
        {
            string congrats = "Based on this transaction we believe you would like these coupons.";
            CouponResponse.orderGuid = order.orderGuid;
            CouponResponse.orderNumber = order.orderNumber;
            
            // blah blah blah
        }
    }

And I wanted to automatically create some kind of string response based on the object on generation. Could I do something like the above and just do something like this.order, or should I just use a constructor and bypass this? I want to try to have this function to be callable in case couponresponse is for whatever reason not created, or simply use this for further data collection later.

Answer 1

Passing an object for 2 properties seems like unnecessary coupling, but you could use the following syntax to make GeneratedCoupons do what you want:

public CouponResponse GeneratedCoupons => GenerateCoupons(this);
