【问题描述】：

我正在使用 PagedList.Mvc 并且当我制作 Filter Like localhost:2241/Samsung 并转到第 2 页浏览器重定向到 localhost:2241/ 而不是本地主机：2241/三星/Page2

我该如何解决这个问题

ProductController.cs

public class ProductController : Controller
{
    private readonly IProductRepository repository;  
    public ProductController(IProductRepository repo)
    {
        repository = repo;
    }
    public ViewResult List(int? page, string category)
    {
        ProductListViewModel model = new ProductListViewModel
        {
            Prodcuts = repository.Products
                .Where(p => category == null || p.Category == category),
            CurrentCategory = category
        };
        return View (model.Prodcuts.ToList().ToPagedList(page ?? 1, 3));
    }
}

List.cshtml

@model IPagedList<OnlineShoppingStore.Domain.Entities.Product>
@using PagedList;
@using PagedList.Mvc;
....
@foreach (var p in Model)
{
    @Html.Partial("ProductSummary",p)
}
@Html.PagedListPager(Model, page => Url.Action("List", new {page }))

ProductListViewModel.cs

public class ProductListViewModel
{
    public IEnumerable <Product> Prodcuts { get; set; } 
    public string CurrentCategory { get; set; }
}

我该怎么办？？

【问题讨论】：

用完整代码编辑的帖子..我不专业，还在学习MVC，所以请告诉我在哪里可以编辑或添加代码..我按照你之前说的category = Model.CurrentCategory ..和@model IPagedList<OnlineShoppingStore.WebUI.Models.ProductListViewModel> 但仍然无法正常工作..请写一个不解释的代码..我很感激..谢谢

ProductController.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using OnlineShoppingStore.Domain.Abstract;
using PagedList;
using PagedList.Mvc;
using OnlineShoppingStore.WebUI.Models;



namespace OnlineShoppingStore.WebUI.Controllers
{
public class ProductController : Controller
{
    private readonly IProductRepository repository;

    public ProductController(IProductRepository repo)
    {
        repository = repo;
    }
    public ViewResult List(int? page, string category, string Filter_Value)
    {

        if (category != null)
        {
            page = 1;
        }
        else
        {
            category = Filter_Value;
        }

        ViewBag.FilterValue = category;

        ProductListViewModel model = new ProductListViewModel
        {
            Prodcuts = repository.Products
                .Where(p => category == null || p.Category == category),
            CurrentCategory = category

        };


                 return View (model.Prodcuts.ToList().ToPagedList(page ?? 1, 3));

           }


       }
 }

ProductListViewModel.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using OnlineShoppingStore.Domain.Entities;

namespace OnlineShoppingStore.WebUI.Models
{
public class ProductListViewModel
{
    public  IEnumerable <Product> Prodcuts { get; set; } 
    public  string CurrentCategory { get; set; }

}
}

List.cshtml

@model IPagedList<OnlineShoppingStore.Domain.Entities.Product>
@using PagedList;
@using PagedList.Mvc;


@{
ViewBag.Title = "Products";
}

@foreach (var p in Model)
{
@Html.Partial("ProductSummary",p)

}

@{

}
<div>

@Html.PagedListPager(Model, page => Url.Action("List", new {page,      Filter_Value = ViewBag.FilterValue }))


Page @(Model.PageCount < Model.PageNumber ? 0 : Model.PageNumber) of @Model.PageCount
