智能感知沒有顯示在LINQ查詢

Question

我有下面的代碼，我用來從數據庫中檢索記錄並將它們放入對象。

這一切工作正常，但智能感知不工作。

我的代碼段，這是工作的罰款：

<% 
    // Get the data context for the SMD-GROUP database 
    SMDGroupDBDataContext db = new SMDGroupDBDataContext(); 

    // Query the database 
    IEnumerable<BestSeller> best_sellers = from bs in db.TOELINE 
         where bs.CusRef == "247HO001" 
         select new BestSeller() 
         { 
          product_code = bs.ProdCode, 
          product_description = bs.ProdDescr 
         }; 

    // Loop through and show each line 
    foreach (BestSeller best_seller in best_sellers) 
    { 
     Response.Write(best_seller.product_code + " - " + best_seller.product_description + "<br/>"); 
    } 
%> 

這是我的網絡配置文件：

你有進口LINQ的命名空間在頁面頂部？

<%@ Import Namespace="System.Linq" %> 

更新：如果你想註冊在web.config中的命名空間，你會做這樣的：

<system.web> 
    ... 
    <pages> 
     <namespaces> 
     <add namespace="System.Linq" /> 
     </namespaces> 
    </pages> 
</system.web>
