传递Html.BeginForm MVC多个参数

我有这样的事情：

public ActionResult Create(int clubid)
{
  var club = db.Clubs.Single(c=>c.Id == clubid);
  ViewBag.Club = club;
  Competition comp = db.Competitions.Create();
  return View(comp)
}

在我的.cshtml：

and in my .cshtml:

@Model Models.Competition
...
@Using(Html.BeginForm())
{
  ...
  <input type="submit" value="Save" />
}

这正常工作与以下邮政动作：

This works fine with the following Post Action:

[HttpPost]
public ActionResult Create(Competition comp)
{
  if (ModelState.IsValid){...}

  return RedirectToAction(...);

}

不过，我想从 @ ViewBag.Club 对象传递一个额外的参数：

However, I want to pass an additional parameter from the @ViewBag.Club object:

[HttpPoSt]
public ActionResult Create(int clubid, Competition comp){...}

我如何code这在 BeginForm ？
