因此，基本上，该网站向用户显示了一个下拉列表以选择类别。以下操作用于让用户选择类别并显示项目：

    public ActionResult SelectResourceCategory()
    {
        return View(new ResourceModel());
    }

    [HttpPost]
    public ActionResult SelectResourceCategory(ResourceModel rm)
    {
        Resource r = new Resource();
        r.CategoryID = rm.Categories.Id;
        List<Resource> GetCourses = new UserBL().GetResourcesByCategoryID(r.CategoryID);
        var vRM = new List<ResourceModel>();

        foreach (Resource rs in GetCourses)
        {
            ResourceModel frm = new ResourceModel();
            frm.ResourceID = rs.Id;
            frm.Title = rs.Title;
            frm.Description = rs.Description;
            frm.Price = (float)rs.Price;
            vRM.Add(frm);
        }

        return View("ShowResources", vRM);
    }

    public ActionResult ShowResources()
    {
        return View();
    }

用户选择后，网页将向用户显示用户可以购买的可用资源列表。使用下面的链接，我将所选项目的resourceID作为参数传递：

@Html.ActionLink("Buy", "BuyResource", new RouteValueDictionary(new { id = item.ResourceID }))

然后动作“ BuyResource”执行以下操作：

        public ActionResult BuyResource(int id)
    {
        Session["Rid"] = id; //GOTO: RedirectFromPayPal
        Resource r = new UserBL().GetResourceByID(id);
        return View(r);
    }

问题：由于某种原因，用户单击“购买”时，页面会将用户重定向回他需要选择类别的页面，特别是“ SelectResourceCategory”操作。它应该重定向到“ BuyResource”操作，我不明白为什么它不这样做。

编辑：

SelectResourceCategory视图：

@model SSD.Models.ResourceModel

@{
ViewBag.Title = "SelectResourceCategory";
Layout = "~/Views/Shared/UserPage.cshtml";
}

<h2>SelectResourceCategory</h2>

<script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script>

@using (Html.BeginForm()) {
@Html.ValidationSummary(true)
<fieldset>
    <legend>ResourceModel</legend>

    <div class="editor-field">
        @Html.DropDownListFor(model => model.Categories.Id, Model.CategoryList)
        @Html.ValidationMessageFor(model => model.Categories.Id)
    </div>

    <p>
        <input type="submit" value="Show available resources" />
    </p>
</fieldset>
}

路由设置：

public static void RegisterGlobalFilters(GlobalFilterCollection filters)
    {
        filters.Add(new HandleErrorAttribute());
    }

    public static void RegisterRoutes(RouteCollection routes)
    {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

        routes.MapRoute(
            "Default", // Route name
            "{controller}/{action}", // URL with parameters
            new { controller = "Home", action = "Index", id = "" } // Parameter defaults
        );



    }

    protected void Application_Start()
    {
        AreaRegistration.RegisterAllAreas();

        RegisterGlobalFilters(GlobalFilters.Filters);
        RegisterRoutes(RouteTable.Routes);
    }

尝试包含目标控制器的名称：

@Html.ActionLink("Buy", "BuyResource", "YOUR CONTROLLER NAME", 
                 new { id = item.ResourceID })

还要确保item.ResourceID可转换为int。

更新：

在你的：

routes.MapRoute(
        "Default", // Route name
        "{controller}/{action}", // URL with parameters
        new { controller = "Home", action = "Index", id = "" } // Parameter defaults
    );

该id=""是不必要的，它可能会干扰您的路由。您可能要考虑使用默认实现：

routes.MapRoute(
      "Default",
      "{controller}/{action}/{id}", 
      new { controller = "Home", action = "Index", id = UrlParameter.Optional }
   );
