Question

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 BLACK = (0, 0, 0) WHITE = (255, 255, 255) BLUE = (0, 0, 255) GREEN = (0, 255, 0) RED = (255, 0, 0) PURPLE

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。

Answer 1

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
