重定向到行動asp.net MVC3

Question

我有動作（分析），我想重定向到通過浮動列表的參數等動作，但始終列表爲空：

• 在action分析器，我填充浮動列表（sfr），並將其作爲參數傳遞給動作（_two或_three或.... _others），但列表變爲空。

  // 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); 
       } 
      } 
  } 
  

那麼，什麼是問題，我該如何修正呢？

嘗試這樣的：

[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); 
}
