Me encantan las extensiones de C# 3.0 y LINQ

Estaba embebiendo una búsqueda en LIVE en una aplicación y fijáos del código anterior (VS2005) al nuevo (VS2008) lo que cambia. Y hacen lo mismo:

Antes:

                             MSNSearchService s = new MSNSearchService();

                SearchRequest searchRequest = new SearchRequest();

                int arraySize = 1;

                SourceRequest[] sr = new SourceRequest[arraySize];

                sr[0] = new SourceRequest();

                sr[0].Source = SourceType.Web;

                searchRequest.Query = "live search";

                searchRequest.Requests = sr;

                searchRequest.AppID = "YOUR_APP_ID_GOES_HERE";

                searchRequest.CultureInfo = "en-US";

                SearchResponse searchResponse;

                searchResponse = s.Search(searchRequest);

                foreach (SourceResponse sourceResponse in searchResponse.Responses)

                {

                    Result[] sourceResults = sourceResponse.Results;

                    WebSites[] retWebSites = new WebSites[sourceResponse.Total];

                    int i=0;

                    foreach (Result sourceResult in sourceResults)

                           retWebSites[i++] = new WebSite(sourceResult.Url);

                }

             return(retWebSites);

Y ahora:

                        SearchRequest liveSearchRequest = new SearchRequest();

             liveSearchRequest.Query = sString;

             liveSearchRequest.Requests = new SourceRequest[1]

{ new SourceRequest() { Source = SourceType.Web } };

             liveSearchRequest.AppID = "YOUR_APP_ID_GOES_HERE";

             liveSearchRequest.CultureInfo = "en-US";

             MSNSearchPortTypeClient liveSearch = new MSNSearchPortTypeClient();

             SearchResponse liveSearchResponse =

liveSearch.Search(liveSearchRequest);

             var p = from res in liveSearchResponse.Responses[0].Results

                    select new WebSite() { sURI = res.Url };

             return(p.ToArray<WebSite>());

He usado la inicialización en constructores para el Live.Requests y LINQ para construir el array de retorno
