ViewResult 没有返回数据

我正在使用 NerdDinner 中的模式。我在测试方法中调用 Index() ，但返回的 ViewREsult 没有数据。因此变量data最终为空。

但是，我知道那里有数据。因为我可以转到监视窗口并展开变量结果并展开viewData->Model->ResultsView，然后我看到“展开将结果视图将枚举IEnumerable”当我展开它时，数据就存在。

知道为什么除非我扩展，否则数据会返回空吗？

谢谢贾斯

   [TestMethod]
    public void Index__Should_Return_1_or_More_lessons()
    {
        var controller = new LessonController(new FakeLessonRepository());

        var result = controller.Index() as ViewResult;

        var data = result.ViewData.Model as IList<Lesson>;
        Assert.IsTrue(data.Count > 0);
    }

原文

I am using the pattern from NerdDinner. I call Index() in my test Method and I the ViewREsult I get back has no data. So the variable data ends up being null.

However, I know that there is data there. Because I can go to the watch window and expand the variable result and expand viewData->Model->ResultsView then I see the "expanding will result view will enumerate the IEnumerable" When I expand it, the data exists.

Any idea why the data comes back null unless I expand?

thanks
Jas
