我有一个问题，我使用Paging，它没有使用简单过滤器过滤，但是当数据来自高级搜索时，我得到以下错误：
传递到字典中的模型项的类型为'System.Collections.Generic.List'1 [WomenNew.Models.News_]'，但此字典需要类型为'PagedList.IPagedList'1 [WomenNew。 Models.News _]”。
如果我可以在没有sql字符串和存储过程的情况下创建我的高级搜索（我在下面解释我的代码）我的问题将得到解决，或者如果我可以转换我的import pygame, random, os, sys

它会很好，我的更改将会很少< / p>
我的控制器高级搜索是：
object List<News_>如果TempData [“news_List”]不为null，则对象传递给Index视图[HttpGet]如果我可以在Index中创建不同的参数，如下代码：
public ActionResult AdvanceSearch_(string DateSFrom, string DateSTo, string Export, string Media, string issue, string subject, string society, string official, string details, string details2, string details3)
{
// create object
List < News_ > newsList_ = new List<News_>();
if (!string.IsNullOrEmpty(details))
{
strQuery2 = "(Details like N'%" + details + "%')";
}
// here other parameter of search is created:
if (!string.IsNullOrEmpty(Media))
{
strQuery2 += "(Media like N'%" + CommonClass.Cpersian(Media) + "%')";
}
// here deferment parameters are joint
strQuery2 = strQuery2.Replace(")(", ") and (");
//here with a stored procedure method object is filled
newsList_ = cmd.GetNewsList(strQuery);
if (newsList_.Count > 0)
{
TempData["news_List"] = newsList_;
if (Export == "Search")
return RedirectToAction("Index", "News_");
else
.........
但提前行动我不知道如何制作.... [HttpGet]
public ActionResult Index(string searchBy, string search, int? page)
{
if (TempData["news_List"] != null)
{
return View(TempData["news_List"]);
}
if (searchBy == "News")
{
return View(db.News_.Where(x => (x.Details.Contains(search)) ||
(x.Issue.Contains(search))).OrderByDescending(s => s.Id).ToList().ToPagedList(page ?? 1,3));
或如何传递到索引视图
我的观点是：
x => (x.Details.....我更愿意转换为将@using PagedList;
@using PagedList.Mvc;
@model IPagedList<WomenNew.Models.News_>
转换为List< News_> newsList_ = new List<News_>();，否则我必须更改我的预先搜索，但如果有必要，我会这样做。
答案 0 :(得分：0)
Stephen Muecke给了我正确的答案，他写信给我：
你需要转换TempData [“news_List”];在返回视图之前，您需要更改ActionIndex，如下所示： if（TempData [“news_List”]！= null） {var list = TempData [“news_List”]作为List; return view（list.ToPagedList（page ?? 1,3））; .....} 我很欣赏Stephen Muecke它为我节省了很多时间。托马斯
