从TempData(MVC C#)投射对象的集合
本文关键字:对象 集合 TempData MVC | 更新日期: 2023-09-27 18:21:09
我正试图将我的对象集合放入TempData中,如下所示:
[HttpPost]
public ActionResult PandoraRemovalTotal2(List<Business.Models.Administration.CorrespondenceRecordViewModel> model, string hdnMem)
{
Business.Administration.Pandora Pandora = new Business.Administration.Pandora();
model = Pandora.DeleteDocs(model);
TempData["model"] = model.Where(m => m.DeleteRow == true);
return RedirectToAction("PandoraDocsDeleted", new {memNum = hdnMem });
}
并通过重定向传递到操作
[HttpGet]
public ActionResult PandoraDocsDeleted(string memNum)
{
var model = (List<Business.Models.Administration.CorrespondenceRecordViewModel>)TempData["model"];
ViewBag.MemNum = memNum;
return View(model);
}
但当我这样做时:
var model = (List<Business.Models.Administration.CorrespondenceRecordViewModel>)TempData["model"];
它为空。我该如何铸造?
而不是
TempData["model"] = model.Where(m => m.DeleteRow == true);
使用
TempData["model"] = model.Where(m => m.DeleteRow == true).ToList();
否则,您正在存储IEnumerable<>的定义,没有任何数据。
