Asp.net mvc 2 asp.net mvc创建视图

我已经创建了一个创建视图。现在的问题是，我想将创建视图中的所有字段以及其他两个不在视图中的字段（创建日期和创建日期）放入数据中。我将如何做到这一点？

关于此示例代码，请查看注释：

// POST: /Dinners/Create

[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Create(Dinner dinner)
{

    if (ModelState.IsValid) {

        try {         
            // here you can add your other fields:
            dinner.CreatedDate = DateTime.Now;
            dinner.CreatedBy = LoggedUserId; // you have to figure out how to get this

            dinnerRepository.Add(dinner);
            dinnerRepository.Save();

            return RedirectToAction("Details", new {id = dinner.DinnerID });
        }
        catch {        
            ModelState.AddRuleViolations(dinner.GetRuleViolations());
        }
    }

    return View(dinner);
}
