如何獲得一個JSON字符串使用休息API的Windows手機？

Question

我的Json格式如下。

{ 
    "code" : o, 
    "message" : "success", 
    "book_list": 
[ 
{"name": "C","price":180}, 
{"name": "C++","price":180}, 
{"name": "C#","price":180}, 
] 
} 

我是一個全新的Windows手機應用程序開發初學者！ 我應該如何從網址獲取書籍清單並將其存儲在字典中的一種東西？（即作爲一個關鍵值對）的Windows Phone 7？

您可以使用this JSON framework for .NET：

using System.Runtime.Serialization; 

    [DataContract] 
    public class BookShop 
    { 

     [DataMember(Name = "code")] 
     public int Code { get; set; } 

     [DataMember(Name = "message")] 
     public string Message { get; set; } 

     [DataMember(Name = "book_list")] 
     public List<Book> Result { get; set; } 
    } 


    [DataContract] 
    public class Book 
    { 
     [DataMember(Name = "name")] 
     public string Name { get; set; } 

     [DataMember(Name = "price")] 
     public int Price { get; set; } 
    } 


public partial class MainPage : PhoneApplicationPage 
{  
    public MainPage() 
    { 
     InitializeComponent(); 

     string json = "{\"code\": 0,\"message\": \"success\",\"book_list\": [{\"name\": \"C\",\"price\": 180}, {\"name\": \"C++\",\"price\": 180 }, {\"name\": \"C#\",\"price\": 180}]}"; 

     var myObjects = JsonConvert.DeserializeObject<BookShop>(json); 

     foreach (var item in myObjects.Result) 
     { 
      Debug.WriteLine("{0} has price {1}", item.Name, item.Price); 
     } 

    } 
}
