PagedList MVC不包含PagedListPager的定义
PagedList MVC不包含PagedListPager的定义
提问于 2016-02-24 06:08:37
我不知道为什么PageCount、PageNumber和PageListPager不包含定义或无法找到。它询问我是否缺少using指令或程序集引用，但我在用户控制器中有它。
Page @(Model.PageCount < Model.PageNumber ? 0 : Model.PageNumber) of @Model.PageCount
to
@Html.PagedListPager( Model, page => Url.Action("Index", new { page, sortOrder = ViewBag.CurrentSort, currentFilter=ViewBag.CurrentFilter }) )注意:以下图片和代码仅供参考

public ViewResult Index(string sortOrder, string currentFilter, string searchString, int? page)
{
ViewBag.CurrentSort = sortOrder;
ViewBag.NameSortParm = String.IsNullOrEmpty(sortOrder) ? "name_desc" : "";
ViewBag.DateSortParm = sortOrder == "Date" ? "date_desc" : "Date";
if (searchString != null)
{
page = 1;
}
else
{
searchString = currentFilter;
}
ViewBag.CurrentFilter = searchString;
var users = from s in db.Users
select s;
if (!String.IsNullOrEmpty(searchString))
{
users = users.Where(s => s.LastName.ToUpper().Contains(searchString.ToUpper())
|| s.FirstMidName.ToUpper().Contains(searchString.ToUpper()));

PageCount、PageNumber等是IPagedList<T>的属性，而不是IEnumerable<T>的属性。您需要在视图中更改模型以使用IPagedList<T>，并包含相关的using语句。
@using PagedList; // add
@using PagedList.Mvc; //add
@model IPagedList<RecreationalServicesTicketingSystem.Models.User> // change
@{
ViewBag.Title = "Users";
}

正如其他人告诉你的那样，你错过了使用PagedList和PagedList.Mvc的。
我可以添加的是，最好在文件Views/Web.Config中添加名称空间的使用。这将允许您在所有视图中使用PagedList和PagedList.Mvc的名称空间，并缩短代码。示例：
<system.web.webPages.razor>
<host factoryType="System.Web.Mvc.MvcWebRazorHostFactory" />
<pages pageBaseType="System.Web.Mvc.WebViewPage">
<namespaces>
<add namespace="System.Web.Mvc" />
<add namespace="System.Web.Mvc.Ajax" />
<add namespace="System.Web.Mvc.Html" />
<add namespace="System.Web.Optimization"/>
<add namespace="System.Web.Routing" />
<add namespace="PagedList" /> <!--Add this line-->
<add namespace="PagedList.MVC" /> <!--Add this line-->
</namespaces>
</pages>
</system.web.webPages.razor>并且不再需要在everyone视图/cshtml中使用使用的
@* @using PagedList; // No more need of this, can delete this line *@
@* @using PagedList.Mvc; // No more need of this, can delete this line *@
@model IPagedList<RecreationalServicesTicketingSystem.Models.User> // change
@{
ViewBag.Title = "Users";
}
..... 这是特别有价值的，当你有一个大项目时，它会缩短你的代码。

您不必在@model指令之前添加@using PagedList和@using PagedList.Mvc。取而代之的是使用PagedList.IPagedList而不只是IPagedList。
@model PagedList.IPagedList<RecreationalServicesTicketingSystem.Models.User>
@using PagedList.Mvc节省时间:如果您在视图中使用DisplayNameFor (如@Html.DisplayNameFor(model => model.CreatedDateTime) )，那么您需要将其更改为：
@Html.DisplayNameFor(model => model.FirstOrDefault().CreatedDateTime)(因为IPagedList改变了语义，所以添加了.FirstOrDefault()。参见Using @Html.DisplayNameFor() with PagedList)。
