Question

朋友和我正在尝试建立一个网站，用户可以在其中创建/编辑/删除国家/地区，通过点击国家/地区旁边的链接，用户可以访问该国家/地区的邮政编码列表。我们有点失败，所以我们希望有人可以帮助我们弄清楚我们做错了什么。

我们的代码如下：

ISOerController.cs



using SkarpSpedition.Models;

using System;
using System.Linq;
using System.Web.Mvc;


namespace SkarpSpedition.Controllers
{
    public class ISOerController : Controller
{
    ISODBContext db = new ISODBContext();

    public ActionResult Index()
    {
        var ISOer = from i in db.ISOes
                    orderby i.Sted ascending
                    select i;
        return View(ISOer.ToList());
    }
    public ActionResult GåTilPostdistrikter(int id)
    {
        return Redirect(@"../../Postdistrikter/" + id);
    }
    ...
}
}

using SkarpSpedition.Models; using System; using System.Linq; using System.Web.Mvc; namespace SkarpSpedition.Controllers { public class ISOerController : Controller { ISODBContext db = new ISODBContext(); public ActionResult Index() { var ISOer = from i in db.ISOes orderby i.Sted ascending select i; return View(ISOer.ToList()); } public ActionResult GåTilPostdistrikter(int id) { return Redirect(@"../../Postdistrikter/" + id); } ... } }

namespace SkarpSpedition.Controllers
{
public class PostdistrikterController : Controller

    PostdistriktDBContext db = new PostdistriktDBContext();

    public ActionResult Index(int id)
    {
        var Postdistrikter = from p in db.Postdistrikts
                             where p.Iso_id == id

                             select p;

        return View(Postdistrikter.ToList());
    }

您应该使用RedirectToAction，而不是Redirect。

public ActionResult GåTilPostdistrikter(int id)
{
    return RedirectToAction( "index", "Postdistrikter", new { id = id } );
}
