Question

public ActionResult listItems()
{
    var getTopStories =  DB.posts.Where(x => x.post_type == "blog").OrderByDescending(x => x.id).Take(4).ToList();

    return View(getTopStories);
}
public ActionResult singleItem()
{
    var single = DB.posts.Where(x => x.post_type == "paper").OrderByDescending(x => x.id).First();
    return View(single);

}

作为我上面的代码，我有两个操作结果方法，但是都具有不同的条件，所以我想在不使用View Bag的情况下在View上显示这两个方法数据，我该怎么做？

让我们假设您有一个带有某些属性（ID，名称等）的Post类。首先创建一个像这样的新类，

public class PostViewModel
{
    public List<Post> PostList { get; set; }
    public Post SinglePost { get; set; }
}

现在在您的操作结果中（不需要两个单独的操作结果）在这样的视图模型中映射数据

public ActionResult SingleAndlistPost()
{
           PostViewModel model=new PostViewModel
            {
                PostList = DB.posts.Where(x => x.post_type == "blog").OrderByDescending(x => x.id).Take(4).ToList(),
                SinglePost = DB.posts.Where(x => x.post_type == "paper").OrderByDescending(x => x.id).First()
            };

           return View(model);
}

最后在您的cshtml中查看这样的访问数据

@model YourProject.YourModel.PostViewModel 
//.......

<p>@Model.SinglePost.MyProperty</p>

foreach (var list in Model.PostList)
{
    <p>@list.MyProperty</p>
}

如何在Asp.net MVC
