索引視圖

model IEnumerable<MvcProductsStore.Models.Item> 
@{ 
    ViewBag.Title = "Store"; 
} 

<h3>Browse Products:</h3> 


<p> 
    Select from @Model.Count() 
    Products: 
</p> 

<ul> 
    @foreach (var item in Model) 
    { 
     <li>@Html.ActionLink(item.IName,"Browse", new { item = item.IName })</li> 
    } 
</ul>

    public class ProductsStoreEntities : DbContext 
    { 
     public DbSet<Product> products { get; set; } 
     public DbSet<Item> item { get; set; }

計數你種方法 後尚未保存的數據庫上下文對象的項目列表中，這樣你應該添加

context.SaveChanges();

Answer 2

請更改返回View（）而不是PartialView（）。

public class StoreController : Controller 
{ 
    // GET: /Store/ 

    ProductsStoreEntities storeDB = new ProductsStoreEntities(); 
    public ActionResult Index() 
    { 
     var items = storeDB.item.ToList(); 
     return View(items); 
    }
