c# - 重定向到操作 asp.net mvc3

Question

我有动作（分析器），我想重定向到传递浮点列表参数的其他动作，但列表总是空的：

• 在动作分析器中，我填充了浮点列表（sfr），并将它作为参数传递给动作（_two 或 _three 或.... _others），但列表变为空。

  // GET: /Historique/
  [HttpGet] 
  public ActionResult Index()
  {
       return View();
  }
  [HttpGet]
  public ActionResult _two(IList<float> sf)
  {
       return View(sf);
  }
  [HttpGet]
  public ActionResult _three(IList<float> sf)
  { 
       return View(sf);
  }
  [HttpGet]
  public ActionResult _four(IList<float> sf)
  {
       return View(sf);
  }
  [HttpGet]
  public ActionResult _five(IList<float> sf)
  {  
       return View(sf);
  }
  [HttpGet]
  public ActionResult _six(IList<float> sf)
  {
       return View(sf);
  }
  [HttpGet]
  public ActionResult _others(IList<float> sf)
  {
       return View(sf);
  }
  [HttpPost]
  public ActionResult Analyser(FormCollection collection)
  {
        IList<float> sfr = new List<float>();
        for (int i = 0; i < Global.seg.Count; i++)
        {
             if (collection.AllKeys.Contains(i.ToString())) {
                 foreach (Point e in Global.seg[i]._pointsListe)
                 {
                      sfr.Add(e._latitude);
                      sfr.Add(e._longitude);
                  }
              }
         }
  
         if (sfr.Count == 4) return RedirectToAction("_two", new { sf = sfr });
         if (sfr.Count == 6) return RedirectToAction("_two", new { sf = sfr });
         if (sfr.Count == 8) return RedirectToAction("_four", new { sf = sfr });
         if (sfr.Count == 10) return RedirectToAction("_five", new { sf = sfr });
         if (sfr.Count == 12) return RedirectToAction("_six", new { sf = sfr });
         else return RedirectToAction("_others",sfr);
           }
      }
  }
  

那么这是怎么回事，我该如何纠正呢？

试试这样：

[HttpPost]
public ActionResult Analyser(FormCollection collection)
{
    IList<float> sfr = new List<float>();
    for (int i = 0; i < Global.seg.Count; i++)
    {
        if (collection.AllKeys.Contains(i.ToString())) 
        {
            foreach (Point e in Global.seg[i]._pointsListe)
            {
                sfr.Add(e._latitude);
                sfr.Add(e._longitude);
            }
        }
    }

    var rvd = new RouteValueDictionary();
    for (int i = 0; i < sfr.Count; i++)
    {
        rvd[string.Format("sf[{0}]", i)] = sfr[i];
    }

    if (sfr.Count == 4) return RedirectToAction("_two", rvd);
    if (sfr.Count == 6) return RedirectToAction("_two", rvd);
    if (sfr.Count == 8) return RedirectToAction("_four", rvd);
    if (sfr.Count == 10) return RedirectToAction("_five", rvd);
    if (sfr.Count == 12) return RedirectToAction("_six", rvd);
    else return RedirectToAction("_others", rvd);
}
