Wie Paging Extrahieren

Question

Ich habe ein kleines Problem für Alter es gewesen

Ich habe meinen derzeitigen serach und Paging bekomme arbeiten, aber ich weiß nicht, was die Paging-Aspekte des Codes ist.

Ich brauche nur den Paging und nicht die Suche, wie ich es schon habe. Dies ist das Tutorial i sowohl für verwendet Paging und Serach, aber nicht wissen, was gerade für das Paging zu extrahieren:

http://www.asp.net/mvc/tutorials/getting-started-with-ef-using-mvc/sorting-filtering-and-paging-with-the-entity-framework-in-an-asp-net-mvc-application 

Dies ist mein Controller für Paging und Suche:

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Web; 
using System.Web.Mvc; 
using PagedList; 
using Games.Models; 


namespace Games.Controllers 
{ 
    public class ShowAllGamesController : Controller 
    { 
     // 
     // GET: /ShowAllGames/ 

     public ActionResult Index(string Ordering, string WordFilter, string DisplaySearchResults, int? CounterForPage) 
     { 
      using (var db = new gamezoneDBEntities()) 
      { 

       ViewBag.Message = TempData["message"]; 
       ViewBag.CurrentSort = Ordering; 
       ViewBag.NameSortParm = String.IsNullOrEmpty(Ordering) ? "GameName" : ""; 
       ViewBag.DateSortParm = Ordering == "ReleaseYearOfGame" ? "DiscriptionOfGame" : "Date"; 


       { 
        TempData["DisplaySearchResult"] = DisplaySearchResults; 

        { 
         ViewBag.search = DisplaySearchResults; 
        } 
        if (Request.HttpMethod == "GET") 
        { 
         DisplaySearchResults = WordFilter; 
        } 
        else if (DisplaySearchResults == "") 
        { 
         ViewData["MyMessage"] = "Nothing Has Been Entered."; 

        } 

        else 
        { 
         CounterForPage = 1; 
        } 

        ViewBag.CurrentFilter = DisplaySearchResults; 

        var FullDatabaseItem = from b in db.tblGames 
              select b; 
        if (!String.IsNullOrEmpty(DisplaySearchResults)) 
        { 
         FullDatabaseItem = FullDatabaseItem.Where(b => b.GameName.ToUpper().Contains(DisplaySearchResults.ToUpper())); 

        } 
        switch (Ordering) 
        { 
         case "HeadlineName": 
          FullDatabaseItem = FullDatabaseItem.OrderBy(b => b.GameName); 
          break; 
         case "DatePosted": 
          FullDatabaseItem = FullDatabaseItem.OrderBy(b => b.ReleaseYear); 
          break; 
         case "DiscriptionDate": 
          FullDatabaseItem = FullDatabaseItem.OrderBy(b => b.ReleaseYear); 
          break; 
         default: 
          FullDatabaseItem = FullDatabaseItem.OrderByDescending(b => b.ReleaseYear); 
          break; 
        } 

        int pageSize = 3; 
        int pageNumber = (CounterForPage ?? 1); 
        var PageNumberResults = FullDatabaseItem.ToPagedList(pageNumber, pageSize); 
        ViewBag.PageNumberResults = FullDatabaseItem.Count(); 
        if (PageNumberResults.Any()) 
        { 

         return View(PageNumberResults); 
        } 

        return View("ErrorView"); 
       } 
      } 
     } 


     public ActionResult AutoCompleteGames() 
     { 
      var db = new gamezoneDBEntities(); 
      string term = this.Request.Params["term"].ToString(); 
      return Json(db.tblGames.Where(games => games.GameName.StartsWith(term)).Select(games => games.GameName), JsonRequestBehavior.AllowGet); 

     } 

     // 
     // GET: /ShowAllGames/Details/5 


     public ViewResult Details(int id) 
     { 
      using (var db = new gamezoneDBEntities()) 
      { 
       tblGame tblgame = db.tblGames.Find(id); 
       return View(tblgame); 
      } 
     } 

     //

     public ActionResult Create()

       return RedirectToAction("Index"); 
      } 
      catch

       return View(); 
      } 
     } 

     //

     public ActionResult Delete(int id) 
     {

      catch 
      { 
       return View(); 
      } 
     } 
    } 
} 

wie Sie Arbeit sehen können gut und richtig. Aber ich weiß nicht, was ich für das Paging brauche kann mir bitte helfen, danke.

Was ich habe versucht:

int pageSize = 3; 
        int pageNumber = (CounterForPage ?? 1); 
        var PageNumberResults = FullDatabaseItem.ToPagedList(pageNumber, pageSize); 
        ViewBag.PageNumberResults = FullDatabaseItem.Count(); 
        if (PageNumberResults.Any()) 
        { 

         return View(PageNumberResults); 
        } 

nicht

dank

EDIT funktioniert:

Dies ist, wo ich nur die Paging wollen

public ViewResult Index() 
      { 
       var Info = db.tblGames.Include(x => x.tblConsole).Where(UserInfo => UserInfo.UserName.Equals(User.Identity.Name)).ToList(); 
       return View(Info); 
      } 

this is my ViewPersonalGames controller 

Unten ist mein Paging, das funktioniert nicht mehr, wenn Sie es zurück zu IEnumerable

EDIT: 


@*<div class="PageCounter"> 
    Page @(Model.PageCount < Model.PageNumber ? 0 : Model.PageNumber) 
    of @Model.PageCount 
    &nbsp; 
    @if (Model.HasPreviousPage) 
    { 

     @Html.ActionLink("<<", "Index", new { CounterForPage = 1, Ordering = ViewBag.CurrentSort, WordFilter = ViewBag.WordFilter }) 
     @Html.Raw("&nbsp;"); 
     @Html.ActionLink("< Previous Page", "Index", new { CounterForPage = Model.PageNumber - 1, Ordering = ViewBag.CurrentSort, WordFilter = ViewBag.WordFilter }) 
    } 
    else 
    { 
     @:<< 
     @Html.Raw("&nbsp;"); 
     @:< Prev 
    } 
    &nbsp; 
    @if (Model.HasNextPage) 
    { 
     @Html.ActionLink("Next Page >", "Index", new { CounterForPage = Model.PageNumber + 1, Ordering = ViewBag.CurrentSort, WordFilter = ViewBag.CurrentFilter }) 
     @Html.Raw("&nbsp;"); 
     @Html.ActionLink(">>", "Index", new { CounterForPage = Model.PageCount, Ordering = ViewBag.CurrentSort, WordFilter = ViewBag.CurrentFilter }) 
    } 
    else 
    { 
     @:Next> 
     @Html.Raw("&nbsp;") 
     @:>> 
    }

public ViewResult Index() 
{ 
    var pageSize = 3; 
    var pageNumber = (CounterForPage ?? 1); 
    var Info = db.tblGames 
     .Include(x => x.tblConsole) 
     .Where(UserInfo => UserInfo.UserName.Equals(User.Identity.Name)) 
     .OrderBy(UserInfo => UserInfo.UserName) 
     .Skip(pageSize * (pageNumber - 1)) // skip first 0, 3, 6, 9, 12, etc, rows 
     .Take(pageSize) // give me only this many rows from the db 
     .ToList(); 
    return View(Info); 
}
