我有以下代码用于从数据库中检索记录并将它们放入对象中。

一切正常，但 Intellisense 根本不工作。

我的代码片段，工作正常：

<%
    // 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/>");
    }
 %>

这是我的网络配置文件：

您是否在页面顶部导入了 Linq 命名空间？

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

更新：如果你想在 web.config 中注册命名空间，你可以这样做：

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