ASP.NET Core request?

Question

ASP.NET

There is a request for the following plan:

Open

[HttpPost]
    public async Task<IActionResult> Ref(RefModel model)
    {
        var countreward = from c in db.Person
                            join g in db.Referal
                            on c.AccountID equals g.memb___id into gg
                            from ggg in gg.DefaultIfEmpty()
 
                            where ggg.referal_reward >= 1
                            where c.RCount >= 1
 
 
                            orderby c.AccountID == User.Identity.Name
 
                            select new Person()
                            {
                                AccountID = c.AccountID,
                                Name = c.Name,
                            };
        var reward = countreward.ToList();
 
        if (ModelState.IsValid)
        {
            if (reward.Count >= 1)
            {
                CSData bonus = db.CSData.First(p => p.AccountID == User.Identity.Name);
                bonus.GP+= 10 * reward.Count;
 
                db.CSData.Update(bonus);
                await db.SaveChangesAsync();
 
                ViewBag.Message = "Да";
            }
            else
            {
                ViewBag.Message = "Нет";
            }
        }
        return View(model);
    }

After clicking on the button, I get all the referrals I need from the Referal table, compare their login according to the required criterion with the Person table, and after that I get +=10 to my login. And now the question is: how do I send +=5 to those for whom I received +=10? I mean, I don’t understand a little how, what and with what to compare.
To put it simply:
How do I send 5 points to those who gave me 10 points?
Thanks for any advice, or example!

Answer 1

Too little data. Where are the model diagrams?
In theory, how can you log your receipts, keeping how much and from whom.
Well, then just calculate at the right time: how much and from whom (grouping from whom and the amount by value, for example), and, if your condition is met, then put down those from whom yours came from +5.
