Question

我有动作（分析器），我想重定向到传递浮动列表参数的其他动作，但总是列表为空：

在动作分析器中，我填充浮动列表（sfr）并将其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);
         }
    }
}

那么问题是什么，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);
}
