Question

I’ve got the following code that I’m using to retrieve records from the database and put them in to objects.

It’s all working fine, but the Intellisense isn’t working at all.

My snippet of code, which is working fine:

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

Here’s my web config file:

Answer 1

Have you imported the Linq namespace at the top of your page?

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

Update: If you’d like to register the namespace in the web.config you would do it like this:

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