C# 视图'；指数'；或者在我运行项目时找不到它的主程序,c#,asp.net-mvc,C#,Asp.net Mvc,这是控制器 namespace DemoforTesting.Controllers { public class ProductController : Controller { DefaultConnection db = new DefaultConnection(); // GET: Product [HttpGet] public ActionResult Index() {

这是控制器

    public class ProductController : Controller

我的观点是

@model IEnumerable<OnLineShoppingCart.Models.Product>

@{
    Layout = null;
}

<!DOCTYPE html>

    <meta name="viewport" content="width=device-width" />

    <p>
        @Html.ActionLink("Create New", "Create")
    </p>
    <table class="table">
        <tr>
            <th>
                @Html.DisplayNameFor(model => model.Prod_Name)
            </th>
            <th>
                @Html.DisplayNameFor(model => model.Unit_Price)

            <th>

            </th>
            <th></th>
        </tr>

    @foreach (var item in Model) {

我右键单击了索引方法并创建了视图，但仍然出现此错误。请有人帮助我，我是MVC新手，因为您将错误的对象传递到视图，MVC无法找到适当的视图。目前，

products

“只是

db.products

的字符串表示，而您的索引视图需要一个

IEnumerable

改变

 [HttpGet]
        public ActionResult Index()
        {
            var products = db.Products.ToString();
            return View(products);

        }

到

 [HttpGet]
        public ActionResult Index()
        {
            var products = db.Products.ToString();
            return View(products);

        }

 [HttpGet]
        public ActionResult Index()
        {
            var products = db.Products.ToList(); //Or some other IENUM
            return View(products);

        }
