Question

我正在使用RestSharp从Cambridge Dictionaries API中为一个简单的Windows Phone 7应用程序检索一些数据。当我执行搜索查询时，我得到JSON中的结果，因为我检查 response.Content 并且实际返回结果但是当我尝试反序列化结果并将其绑定到列表框元素时它不会工作。这是代码：

请求处理程序类

namespace RestAPI
{
/// <summary>
/// This class is responsible for communicating with a RESTful web service.
/// </summary>
public class RequestHandler
{
    //this property stores the API key
    readonly string Accesskey = "";

    //this property stores the base URL
    readonly string BaseUrl =  "https://dictionary.cambridge.org/api/v1/dictionaries/british/search";
    //readonly string BaseUrl = "https://dictionary.cambridge.org/api/v1/dictionaries";

    //Instance of the RestClient
    private RestClient client;



    //Constructor that will set the apikey 
    public RequestHandler(string Access="Doh52CF9dR8oGOlJaTaJFqa05PysEKIbEvd9VNQ7CqB81MyTUCggGNQO7PDyrsyY")
    {
        this.Accesskey = Access.Trim();
        client = new RestClient(this.BaseUrl);
    }

    //Execute function

    public List<SearchResult> Execute(string word)
    {
        List<SearchResult> data = new List<SearchResult>();
        RestRequest request = new RestRequest();
        request.RequestFormat = DataFormat.Json;
        request.AddHeader("accessKey",Accesskey);
        request.AddParameter("pageIndex","1");
        request.AddParameter("pageSize","5");
        request.AddParameter("q",word.Trim());


        client.ExecuteAsync<List<SearchResult>>(request,(response)=>{


            try
            {
            var resource = response.Data;

            if(response.ResponseStatus == ResponseStatus.Completed)
                MessageBox.Show(resource.Count.ToString());


            //MessageBox.Show(resource.ToString());

            foreach(SearchResult s in resource)
            {
                data.Add(s);
               }
            }
        catch(Exception e)
        {
            MessageBox.Show(e.Message);
        }


    });

        return data;    
      }
}
}

主页文件后面的代码。

namespace RestAPI
{
public partial class MainPage : PhoneApplicationPage
{
    public RequestHandler handler = new RequestHandler();
    public List<SearchResult> info = new List<SearchResult>();

    // Constructor
    public MainPage()
    {
        InitializeComponent();
    }

    private void search_Click(object sender, RoutedEventArgs e)
    {
        info = handler.Execute(searchBox.Text);
        listBox1.Items.Add("Testing");
        foreach (SearchResult s in info)
        {
            listBox1.Items.Add(s.entryLabel);

        }
    }
}
 }

要将数据反序列化的模型类。

namespace RestAPI
{
public class SearchResult
{

    public string entryLabel{get;set;}
    public string entryUrl{get;set;}
    public string entryId { get; set; }

}

}

正在返回的示例JSON数据。

{
"resultNumber": 49,
"results": [
    {
        "entryLabel": "dog noun  ANIMAL ",
        "entryUrl": "http://dictionary.cambridge.org/dictionary/british/dog_1",
        "entryId": "dog_1"
    },
    {
        "entryLabel": "dog noun  PERSON ",
        "entryUrl": "http://dictionary.cambridge.org/dictionary/british/dog_2",
        "entryId": "dog_2"
    },
    {
        "entryLabel": "dog verb  FOLLOW ",
        "entryUrl": "http://dictionary.cambridge.org/dictionary/british/dog_3",
        "entryId": "dog_3"
    }
],
"dictionaryCode": "british",
"currentPageIndex": 1,
"pageNumber": 17
}

这样的事情可以解决问题：

public class SearchResultResponse
{
    public int ResultsNumber { get; set; }
    public IEnumerable<SearchResult> Results { get; set; }
}

public class SearchResult
{

    public string entryLabel { get; set; }
    public string entryUrl { get; set; }
    public string entryId { get; set; }
}

SearchResultResponse obj = JsonConvert.DeserializeObject<SearchResultResponse>(json);

在您的情况下，您可能需要像这样调用client.ExecuteAsync：

client.ExecuteAsync<SearchResultResponse>

数据未反序列化为List <searchresults> </searchresults>
