Bing Search - Add query option with BingContainer.cs

Question

Hi -

How can I add a query option that isn't included in the parameters of the method? for example:

        // Can't add "?$top=5" here or throws an exception
        string rootUrl = "https://api.datamarket.azure.com/Bing/Search";
        var bingContainer = new Bing.BingSearchContainer(new Uri(rootUrl));
        // Configure the bingContainer to use your credentials.
        bingContainer.Credentials = new NetworkCredential(AccountKey, AccountKey);
        // The Web method takes: query, market, adult, latitude, longitude, web file type.
        var webQuery = bingContainer.Web(query, null, null, null, null, null);
        // tried this - doesn't help anything
        webQuery.AddQueryOption("$top", 5);
        // neither webQuery.Expression nor webQuery.RequestUri shows "$top"
        Console.WriteLine(webQuery.Expression);
        Console.WriteLine(webQuery.RequestUri);
        // The query runs fine but isn't limted to 5 results

As the code comments show, I tried to add a $top - doesn't work. Even though I used AddQueryOption (which seems like a winner), it doesn't change anything, doesn't affect the expression or Uri. Any ideas?

Thanks - Victor David

Answer 1

I dug around in BingContainer to see how it was doing things. Need to use the return value from AddQueryOption to reassign the query object,  like so:

// yay!
webQuery = webQuery.AddQueryOption("$top", 5);

That does it! Well, maybe that'll help somebody else.
