在MVC4中向控制器中的所有动作传递一个固定id

我有一个控制器ScoreController所以这个控制器中的所有动作都需要一个名为ScheduleId的id所以我必须*viewbag*并再次恢复。我的问题是我如何将此值设置为一个固定值和我所有的视图(即Edit，*Delete*，Create，*list*)和动作使用它而不传递?

控制器代码:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using EducationMVC.Models;
using EducationMVC.PresentationClass;
using EducationRepositor;
using DomainClasses;
namespace EducationMVC.Controllers
{
    public class ScoreController : Controller
    {
        //
        // GET: /Score/
        private readonly ScoreRepository obj = new ScoreRepository();
        PresentationClass.DateConverter objconverterDate=new DateConverter();
        public ActionResult Index(string scheduleId)
        {
            List<ScoreStudentPresentation> objlist=new List<ScoreStudentPresentation>();
            List<Score> model = obj.GetStudentlistOfSchedule(scheduleId);
            foreach (Score t in model)
            {
                ScoreStudentPresentation objpres=new ScoreStudentPresentation();
                objpres.ConfirmScore = objconverterDate.ConvertToPersianToShow(t.DateOfSubmit);
                objpres.Family = t.Student.LastName;
                objpres.Name = t.Student.Name;
                objpres.Score = t.Point;
                objpres.StudentNumber = t.Student.StudentId.ToString();
                objpres.id = t.Id.ToString();
                objlist.Add(objpres);
            }
            ViewBag.ScheduleId = scheduleId;
            return View(objlist);
        }
        public ActionResult Create(string ScheduleId)
        {
            return View("Create");
            // return View();
        }
        [HttpPost]
        public ActionResult Create(Score score)
        {
            obj.AddNewScore(score);
            obj.Save();
            return RedirectToAction("Index", "Score");
        }
        public ActionResult Edit(int id)
        {
            return View(obj.FindScoreById(id));
        }
        [HttpPost]
        public ActionResult Edit(Score score)
        {
            if (ModelState.IsValid)
            {
                obj.Update(score);
                obj.Save();
            }
            return RedirectToAction("Index", "Score");
        }
    }
}

正如你所看到的，我传递了ScheduleId创建和索引，我必须为另一个动作，因为我需要ScheduleId。我想避免这种

问好。
