Question

我正在做一个带有书架的小型ASP.NET MVC 3测试应用程序，我可以在其中列出“书籍”，并将这些内容借给“Loaners”。

我想在一个视图中显示我的书籍和我的Loaners，并因此创建了一个名为BooksViewModel的ViewModel，但我无法弄清楚为什么我无法列出我的“书籍”。我可以做“foreach（模型中的var项目）”，只触摸里面的“Books”，没有Books属性。

namespace MyTest.Models
{
    /// <summary>
    /// Represents a book
    /// </summary>
    public class Book
    {
        public int ID { get; set; }
        public string Title { get; set; }
        public string Author { get; set; }
        public string ISBN { get; set; }
        public virtual Loaner LoanedTo { get; set; }
    }

    /// <summary>
    /// Represents a Loaner
    /// </summary>
    public class Loaner
    {
        public int ID { get; set; }
        public string Name { get; set; }
        public virtual ICollection<Book> Loans { get; set; }
    }

    /// <summary>
    /// Bookshelf Database Context
    /// </summary>
    public class BookshelfDb : DbContext
    {
        public DbSet<Book> Books { get; set; }
        public DbSet<Loaner> Loaner { get; set; }
    }     
}

我的控制器：

    BookshelfDb bookshelf = new BookshelfDb();

    public ActionResult Index()
    {
        var books = from book in bookshelf.Books
                        select book;

        var loaners = from loaner in bookshelf.Loaner
                         select loaner;

        var bookViewModel = new BooksViewModel(books.ToList(),loaners.ToList());

        return View(bookViewModel);
    }

我的ViewModel

public class BooksViewModel
{
    public BooksViewModel(List<Book> books, List<Loaner> loaners)
    {
        this.Books = books;
        this.Loaners = loaners;
    }
    public List<Book> Books { get; private set; }
    public List<Loaner> Loaners { get; private set; }
}

我的观点

@model IEnumerable<MyTest.ViewModels.BooksViewModel>
@foreach (var item in Model.Books)
{
    @item.Title
}

非常感谢任何提示或代码修复！

在我看来，就像你在视图声明中得到了错误的模型类型一样。尝试：

@model MyTest.ViewModels.BooksViewModel

@foreach (var item in Model.Books)
{    
   @item.Title
}

如何在MVC中将两个列表作为模型发送
