我试图使用必应搜索API来查找图像作为背景到我的应用程序内的瓷砖。我已经在我的项目中包含了BingSearchContainer.cs，但我不能使它与这里提供的样例代码工作。

任何关于如何在我的Windows Phone 8应用程序中使用必应搜索API的指导将不胜感激!

谢谢你的回答

我希望你已经有一个AccountKey，所以我不会告诉你必须得到一个。

实施

    首先，将BingSearchContainer.cs添加到项目
  1. 实现Bing API快速入门中的c#示例代码;代码
    2. 之后，右键单击References，选择Manage NuGet Packages…查找并安装Microsoft.Data.Services.Client.WindowsP。

  2. 修改示例代码，使其与Windows Phone一起工作:

    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);
    }
}

  1. 现在，让我们使用我提供给你的代码:

    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";
            });
        }
    }
}
