Question

我正在尝试迭代存储在ASP.NET MVC4项目中控制器的字段中的IList。我试图在我的一个视图中执行此操作，以便能够生成与通过搜索查询收集的某些信息相对应的HTML元素。代码可以在下面看到。

控制器

public class HomeController : Controller
{
    public static int MovieHits;
    public static int PeopleHits;
    public static IList<Model.MovieDto> Movies;
    public static IList<Model.PersonDto> People;

public ActionResult SearchResults(string input)
    {
        ViewBag.Title = "Search";
        ViewBag.Message = "Your search returned the following match(es).";

        var results = Model.ModelController.UniversalSearch(input);

        Movies = results.MovieListForUser;
        People = results.PersonListForUser;
        MovieHits = Movies.Count;
        PeopleHits = People.Count;

        return View();
    }

THE VIEW

        <div id="movieResults">
            @foreach (var movie in HomeController.Movies)
            {
                <span class="movieResult">@movie.Title</span><br/>
            }
        </div>

问题是我在浏览器中尝试生成HTML时出现编译错误。错误信息可以在下面看到，但要注意;它已被谷歌从丹麦语翻译成英语，但从它的外观来看，它看起来很容易理解= P

错误

描述：在编译处理此请求所需的资源期间发生错误。阅读有关错误的以下详细信息，并对源代码进行必要的更改。 kompileringsfunktion出错：CS0012：类型'Model.MovieDto'在未引用的程序集中定义。添加对程序集“Model，Version = 0.0.0.0，Culture = neutral，PublicKeyToken = null”的引用。来源错误：

Line 21: <div id="movieResults">

我尝试重新添加对Model类的引用（它位于sollution中，但是在另一个项目中。我是Razor和ASP.NET的新手，所以我有点迷失在这里。我估计它可能是我的Web.config文件中的错误或我的ASP.NET临时文件中的错误，但尝试通过这两种尺寸解决问题已经无处可去。然后再次，因为我对此非常新，它可能也就像我做错事一样简单。不过要提前感谢。

要修复错误，请尝试添加程序集，其中dto类声明为web.config中的编译程序集（请参阅Fixing Error CS0012）。但...

使用静态控制器字段将数据从控制器传递到视图并不是一个好主意。您将如何处理多个同时请求？因此，使用ViewBag或创建适当的模型并将其传递给视图：

public class SearchResultModel
{
    public IList<Model.MovieDto> Movies { get; set; }
    public IList<Model.PersonDto> People { get; set; }
}

创建并传递

public ActionResult SearchResults(string input)
{
    ViewBag.Title = "Search";
    ViewBag.Message = "Your search returned the following match(es).";

    var results = Model.ModelController.UniversalSearch(input);

    var model = new SearchResultModel {
       Movies = results.MovieListForUser,
       People = results.PersonListForUser
    };

    return View(model);
}

查看：

@model Your.Namespace.SearchResultModel

...    
<td> 
<div id="movieResults">
@foreach (var movie Model.Movies) { 
    <span class="movieResult"> @movie.Title </span><br/>
}
<span>Total movie hits: @Model.Movies.Count</span>
...

每个Web请求都会导致单独创建模型。

在视图中使用foreach循环迭代ASP.NET中控制器的字段
