Question

我在这个问题上遇到了一个小问题

我目前有serach和分页工作，但我不知道代码的分页方面是什么。

我只需要分页，不需要搜索，因为我已经拥有它。这是我用于分页和搜索的教程，但不知道要为分页提取什么：

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

这是我的分页和搜索控制器：

你可以看到两者都运作良好且是正确的。但我不知道我需要什么分页，任何人都可以帮助我，谢谢。

我尝试过的事情：

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

                        return View(PageNumberResults);
                    }

不起作用

谢谢

编辑：

这就是我想要的分页

   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

以下是我的分页，如果您将其恢复为IEnumerable

，该分页将不再有效

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);
}
