Question

我今天试图给ASP.NET一个镜头并用一个名为navigation的表创建一个简单的数据库。当我将数据从控制器发送到视图但是我注意到我可以使用@ model.name但它不会让我在模型上使用foreach循环而我无法找出原因。

这是代码

using System.Linq;
using System.Net;
using System.Web;
using System.Web.Mvc;
using WebApp_OpenIDConnect_DotNet.Models;

namespace WebApp_OpenIDConnect_DotNet.Controllers
{
    public class navigationsController : Controller
    {
        private edulyEntities db = new edulyEntities();

        // GET: navigations
        public ActionResult ShowMenu()
        {
            return View(db.navigation.ToList().OrderBy(n => n.nav_order));
        }

        protected override void Dispose(bool disposing)
        {
            if (disposing)
            {
                db.Dispose();
            }
            base.Dispose(disposing);
        }
    }
}

查看：

@model IEnumerable<WebApp_OpenIDConnect_DotNet.Models.navigation>

@foreach (var item in Model)
{
    <li>
        <a href="@Url.Action(Model.action, Model.controller)" class="dont-break-out">
            <i class="@Model.glyphicon_text"></i>
            <span class="smScreenHideText">@Model.name</span>
        </a>
    </li>
}

数据库表

 public partial class navigation
{
    public int id { get; set; }
    public string name { get; set; }
    public int nav_order { get; set; }
    public string glyphicon_text { get; set; }
    public string controller { get; set; }
    public string action { get; set; }
}

如果glyphicon_text是WebApp_OpenIDConnect_DotNet.Models.navigation类中的属性，那么您应该更新foreach内的代码，如下所示：

@foreach (var item in Model)
{
   <li>
     <a href="@Url.Action(Model.action, Model.controller)" class="dont-break-out">
        <i class="@item.glyphicon_text"></i>
        <span class="smScreenHideText">@item.name</span>
     </a>
   </li>
}

请注意，我已将@Model替换为@item，因为您现在位于foreach的范围内，并且您已宣布item为> The following restricted PHP modes have non-empty values: > [error] open_basedir and disable_functions.

@foreach不适合模特
