不在局部视图中显示 take(4) 数据

Question

i 在 ASP.Net MVC 中创建新闻站点。

我想在数据库中显示 4 个最后一行数据，当它们的类型是 ("SP") 时。

但是当我 运行 Project 只显示最后一行时。

如何解决？

我的数据库：Database Record

我创建存储库这个 .

public List<Tbl_News> GetSpecialNews()
    {
        try
        {
            List<Tbl_News> qGetSpecialNews = (from a in db.Tbl_News
                                   where a.Type.Equals("sp")
                                   select a).OrderByDescending(s => s.ID).Skip(0).Take(4).ToList();
            return qGetSpecialNews;
        }
        catch (Exception)
        {

            return null;
        }
    }

局部视图：

@{
            foreach (var item in RNews.GetSpecialNews())
            {
                <div class="sec-special-page-news-img">
                    <img src="~/Content/img/NewsPic/@item.Image" />
                </div>
                <div class="sec-special-page-news-body">
                    <a href="@item.ID">@item.Title</a>
                    <ul class="mini-info">
                        <li>@item.Date<span class="glyphicon glyphicon-time"></span></li>
                    </ul>
                </div>
            }
        }

家庭控制：

public class HomeController : Controller
{
    Rep_News RNews = new Rep_News();
    // GET: Home
    public ActionResult Index()
    {
        var q = RNews.GetSpecialNews();
        return View(q);
    }
}

Your code should return 4 records. Also, you do not need to call RNews.GetSpecialNews() method again in your view as your are doing that in your action method and passing it to the view. Just do a foreach on the Model

public List<Tbl_News> GetSpecialNews() {
    try {
        List<Tbl_News> qGetSpecialNews = 
            (from a in db.Tbl_News
             where a.Type.Equals("sp")
             select a)
            .OrderByDescending(s => s.ID)
            .Take(4)
            .ToList();
        return qGetSpecialNews;
    }
    catch (Exception) {
        return null;
    }
}

@model List<Tbl_News>
@{
    foreach (var item in Model)
    {
        <div class="sec-special-page-news-img">
            <img src="~/Content/img/NewsPic/@item.Image" />
        </div>
        <div class="sec-special-page-news-body">
            <a href="@item.ID">@item.Title</a>
            <ul class="mini-info">
                <li>@item.Date<span class="glyphicon glyphicon-time"></span></li>
            </ul>
        </div>
    }
