How do I use the Bing Search API in Windows Phone?

问题

I'm trying to use the Bing Search API to find images as backgrounds to the tiles inside of my app. I've included the BingSearchContainer.cs in my Project but I can't make it work with the sample code provided here.

Any guidelines for how to use the Bing Search API inside of my Windows Phone 8 app would be appriciated!

Thanks for any answer.

I expect that you already have a AccountKey so I wont tell you have to get one.

Implementation

1. First of all, add the BingSearchContainer.cs to your project
2. Implement the sample C# code found in the Bing API Quick Start & Code
3. Thereafter, right-click References and choose Manage NuGet Packages... and search for, and install, Microsoft.Data.Services.Client.WindowsP.

4. Modify the sample code so that it work with Windows Phone:

   using Bing;
   using System;
   using System.Data.Services.Client;
   using System.Linq;
   using System.Net;
   
   namespace StackOverflow.Samples.BingSearch
   {
       public class Finder
       {
           public void FindImageUrlsFor(string searchQuery)
           {
               // Create a Bing container. 
               string rootUri = "https://api.datamarket.azure.com/Bing/Search";
               var bingContainer = new Bing.BingSearchContainer(new Uri(rootUri));
               bingContainer.UseDefaultCredentials = false;
   
               // Replace this value with your account key. 
               var accountKey = "YourAccountKey";
   
               // Configure bingContainer to use your credentials. 
               bingContainer.Credentials = new NetworkCredential(accountKey, accountKey);
   
               // Build the query. 
               var imageQuery = bingContainer.Image(query, null, null, null, null, null, null);
   
               imageQuery.BeginExecute(_onImageQueryComplete, imageQuery);
   
           }
   
           // Handle the query callback. 
           private void _onImageQueryComplete(IAsyncResult imageResults)
           {
               // Get the original query from the imageResults.
               DataServiceQuery<Bing.ImageResult> query =
                   imageResults.AsyncState as DataServiceQuery<Bing.ImageResult>;
   
               var resultList = new List<string>();
   
               foreach (var result in query.EndExecute(imageResults))
                   resultList.Add(result.MediaUrl);
   
               FindImageCompleted(this, resultList);
           }
   
           public event FindImageUrlsForEventHandler FindImageUrlsForCompleted;
           public delegate void FindImageUrlsForEventHandler(object sender, List<string> result);
       }
   }
   

Example

1. And now, let's use the code I provided you with:

   using Bing;
   using System;
   using System.Data.Services.Client;
   using System.Linq;
   using System.Net;
   
   namespace StackOverflow.Samples.BingSearch
   {
       public class MyPage
       {
           private void Button_Click_1(object sender, RoutedEventArgs e)
           {
               var finder = new Finder();
               finder.FindImageUrlsForCompleted += finder_FindImageUrlsForCompleted;
               finder.FindImageUrlsFor("candy");
           }
   
           void finder_FindImageUrlsForCompleted(object sender, List<string> result)
           {
               Deployment.Current.Dispatcher.BeginInvoke(() =>
               {
                   foreach (var s in result)
                       MyTextBox.Text += s + "\n";
               });
           }
       }
   }
