Question

我在VS2012中使用NSubstitute运行测试，我正在尝试将模型转换为列表，或者我可以计算的东西。这是代码：

    [TestMethod]
    public void StartedGame()
    {
        // arrange
        var repo = Substitute.For<IGameRepository>();
        IEnumerable<Game> expectedGames = new List<Game> 
            {
                new Game{ gameTypeID = 1, hasStarted = false, ID = 1, isOver = false, isPublic = true, maxPlayers = 2, someoneReported = false},
                new Game{ gameTypeID = 1, hasStarted = false, ID = 2, isOver = false, isPublic = true, maxPlayers = 2, someoneReported = false},
                new Game{ gameTypeID = 2, hasStarted = false, ID = 3, isOver = false, isPublic = true, maxPlayers = 2, someoneReported = false},
                new Game{ gameTypeID = 2, hasStarted = false, ID = 4, isOver = false, isPublic = true, maxPlayers = 2, someoneReported = false},
                new Game{ gameTypeID = 1, hasStarted = false, ID = 5, isOver = false, isPublic = true, maxPlayers = 2, someoneReported = false}
            };
        repo.GetGames().Returns(expectedGames);
        var sut = new GameController(repo);

        // act
        var actual = sut.GameMenuStart();
        // assert
        //Assert.IsInstanceOfType(actual, typeof(ViewResult));
        var viewResult = actual as ViewResult;

        Assert.IsNotNull(viewResult);
    }

当我调试时，我可以将鼠标悬停在'viewResult'上并看到模型，然后我会看到条目和'计数'，但我怎样才能达到它？我试过像这样投射到'Game'对象：

Game[] theModel = (Game[])viewResult.Model;

要列出更多，但总是失败。有什么想法吗？

编辑：viewResult的类型为：System.Web.Mvc.ViewResult

以下是此函数中的其余代码：

        var repo = Substitute.For<IGameRepository>();
        IEnumerable<Game> expectedGames = new List<Game> 
            {
                new Game{ gameTypeID = 1, hasStarted = false, ID = 1, isOver = false, isPublic = true, maxPlayers = 2, someoneReported = false},
                new Game{ gameTypeID = 1, hasStarted = false, ID = 2, isOver = false, isPublic = true, maxPlayers = 2, someoneReported = false},
                new Game{ gameTypeID = 2, hasStarted = false, ID = 3, isOver = false, isPublic = true, maxPlayers = 2, someoneReported = false},
                new Game{ gameTypeID = 2, hasStarted = false, ID = 4, isOver = false, isPublic = true, maxPlayers = 2, someoneReported = false},
                new Game{ gameTypeID = 1, hasStarted = false, ID = 5, isOver = false, isPublic = true, maxPlayers = 2, someoneReported = false}
            };
        repo.GetGames().Returns(expectedGames);
        var sut = new GameController(repo);

Answer 1

var theList = viewResult.Model as IEnumerable<Game>;

这就是诀窍。

Answer 2

由于它是一个IEnumerable，如果你想让它成为一个数组，你可以使用“ToArray”方法。

Game[] theModel = viewResult.ToArray();

但.Count应该有用吗？

我们可以看到“repo.GetGames()”
