如何将参数传递给ASP.NET MVC 2中的自定义ActionFilter？

public class CustomActionFilter : ActionFilterAttribute
{
    public override void OnActionExecuting(ActionExecutingContext filterContext)
    {
        // 在此处处理传递的参数
        var parameterValue = filterContext.ActionParameters["parameterName"];
        // 其他逻辑处理
        base.OnActionExecuting(filterContext);
    }
}

[CustomActionFilter]
public class MyController : Controller
{
    public ActionResult MyAction(string parameterName)
    {
        // Action逻辑
        return View();
    }
}

public ActionResult MyAction(string parameterName)
{
    // Action逻辑
    return View();
}
