我这里有一个非常大的问题。我正在尝试列出所有车辆的列表并将它们推送到View，但它不能像我想象的那样工作。不知道怎么办？我会非常感谢

要在视图中显示对象列表，基本上需要：

在Controller中，使用View(<data>)方法将对象列表发送到View：

public ActionResult Index() {
    OurDBContext db = new OurDBContext();
    return View(db.car.ToList());
}

在视图中，接收模型变量中的对象列表：

@model List<Car>

<html>
...
<body>
    @foreach(var item in Model) {
        <p>@item.Property</p>
    }
</body></html>
