我有一个StartController，它包含一个存储库中的电影列表。我想用那个列表，不仅在StartController中而且在GenreController中但我不知道怎么用。这是我的StartController:

namespace IMDB
{
    public class StartController : Controller
    {
        // GET: Start
        public ActionResult Index()
        {
            var movies = GetMoviesFromRepository();
            return View(movies);
        }
        // GET: Details
        public ActionResult Movie(int id)
        {
            var allMovies = GetMoviesFromRepository();
            var movie = allMovies.FirstOrDefault(x => x.MovieID.Equals(id));
            return View(movie);
        }
        private List<Movie> GetMoviesFromRepository()
        {
            var movies = new List<Movie>();
            var movie1 = new Movie();
            movie1.MovieID = 1;
            movie1.Title = "Terminator";
            movie1.Genre = "Comedy";
            movie1.Year = 1984;
            movie1.Country = "America";
            movie1.Picture = "http://vignette4.wikia.nocookie.net/tvdatabase/images/8/89/Terminator_(1984).jpg";
            movies.Add(movie1);
            var movie2 = new Movie();
            movie2.MovieID = 2;
            movie2.Title = "Terminator 2: Judgement Day";
            movie2.Genre = "Romantic";
            movie2.Year = 1991;
            movie2.Country = "America";
            movie2.Picture = "https://upload.wikimedia.org/wikipedia/en/8/85/Terminator2poster.jpg";
            movies.Add(movie2);
            return movies;
        }
    }
}

这是GenreController我想从StartController访问列表:

namespace IMDB.Controllers
{
    public class GenreController : Controller
    {
        // GET: Genre
        public ActionResult Genre(string genre)
        {
            var allGenres = GetMoviesFromRepository();
            // Some code goes here
            return View();
        }
    }
}

显然这不起作用。但是我不知道如何让我的列表在GenreController工作

继承，存储库，MVC

这就是div的意思:

从控制器中提取电影存储库逻辑并将其放入自己的类中。它的目的将是检索您的电影。

    public class MovieRepository {
        public List<Movie> GetMoviesFromRepository()
        {
            var movies = new List<Movie>();
            var movie1 = new Movie();
            movie1.MovieID = 1;
            movie1.Title = "Terminator";
            movie1.Genre = "Comedy";
            movie1.Year = 1984;
            movie1.Country = "America";
            movie1.Picture = "http://vignette4.wikia.nocookie.net/tvdatabase/images/8/89/Terminator_(1984).jpg";
            movies.Add(movie1);
            var movie2 = new Movie();
            movie2.MovieID = 2;
            movie2.Title = "Terminator 2: Judgement Day";
            movie2.Genre = "Romantic";
            movie2.Year = 1991;
            movie2.Country = "America";
            movie2.Picture = "https://upload.wikimedia.org/wikipedia/en/8/85/Terminator2poster.jpg";
            movies.Add(movie2);
            return movies;
        }
    }

然后在你的控制器中，添加一个构造函数来初始化一个私有变量，该变量将保存你的MovieRepository。然后，在任何想要检索电影集合的地方，只需调用movieRepository.GetMoviesFromRepository()。

        public class StartController : Controller {
            private readonly MovieRepository movieRepository;
            public StartController()
            {
                this.movieRepository = new MovieRepository();
            }
            // GET: Start
            public ActionResult Index()
            {
                var movies = movieRepository.GetMoviesFromRepository();
                return View(movies);
            }
            // GET: Details
            public ActionResult Movie(int id)
            {
                var allMovies = movieRepository.GetMoviesFromRepository();
                var movie = allMovies.FirstOrDefault(x => x.MovieID.Equals(id));
                return View(movie);
            }
        }
