如何在Windows Phone中使用Bing Search API？

Question

我正在尝试使用Bing Search API来查找图像作为应用程序内部图块的背景.我在我的项目中包含了BingSearchContainer.cs但我无法使用此处提供的示例代码.

有关如何在我的Windows Phone 8应用程序中使用Bing Search API的任何指导原则都会受到关注!

谢谢你的回答.

我希望你已经拥有一个AccountKey,所以我不会告诉你必须得到一个.

履行

1. 首先,将BingSearchContainer.cs添加到您的项目中
2. 实现Bing API快速入门和代码中的示例C#代码
3. 此后,右键单击" 引用"并选择" 管理NuGet包...",然后搜索并安装Microsoft.Data.Services.Client.WindowsP.

4. 修改示例代码,使其适用于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);
       }
   }
   

例

1. 现在,让我们使用我提供的代码:

   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";
               });
           }
       }
   }
