我正在使用 RestSharp 从剑桥词典 API中检索一些数据，用于一个简单的 Windows Phone 7 应用程序。当我执行搜索查询时，我会以 JSON 格式获得结果，因为我检查了response.Content并且实际上返回了结果，但是当我尝试反序列化结果并将其绑定到列表框元素时，它将不起作用。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);

        }
    }
}
 }

数据被反序列化到的模型类。

namespace RestAPI
{
public class SearchResult
{

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

}

}

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
}

这样的事情应该可以解决问题：

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，您可能必须这样称呼client.ExecuteAsync：

client.ExecuteAsync<SearchResultResponse>
