反序列化JSON数组列出WP7

Question

我需要从内部JSON子阵列获取的数据，但它没有得到转换成列表，下面是我的JSON字符串

{“responseCode”：“0”，“responseObject” ：{“TotalRecords”：25，“TotalDisplayRecords”：25，“aaData”：[{“InvoiceId”：16573，“somedata ..”，“appCrmAccount（一些标题，总共100个这样的标题） amount”：40086.00， invoiceNumber “：” 12，帐户名 “：” dfgAsfsadf “” dueDateStr “：” 2012" 年4月24日（数据将进入名单）

这里是我的代码：

var djson = new DataContractJsonSerializer(typeof(dataList)); 
var stream = new MemoryStream(Encoding.UTF8.GetBytes(json)); 
dataList result = (dataList)djson.ReadObject(stream);//not getting execute 

善意帮助.. 在此先感谢。

究竟你需要做的是采取数组元素回报为DataContract及其子成员的数据成员作为

[DataContract] 
public class mainresponse 
{ 
[DataMember] 
public resultmap arrayelement { get; set; } 
} 
[DataContract] 
public class resultmap 
{ 
[DataMember] 
public string substringhere { get; set; } 
}  
var djson = new DataContractJsonSerializer(typeof(Mainresponse)); 
var stream = new MemoryStream(Encoding.UTF8.GetBytes(responsestring)); 
mainresponse result = (mainresponse)djson.ReadObject(stream); 

，它...

试试这个

private void btnAdd_Click(object sender, RoutedEventArgs e) 
{ 
    WebClient proxy = new WebClient(); 
    proxy.DownloadStringCompleted += new DownloadStringCompletedEventHandler(proxy_DownloadStringCompleted); 
    proxy.DownloadStringAsync(new Uri("")); 
} 

，需要解析返回的JSON如下。在创建DataContractJsonSrrializer实例的参数中，我们传递了Student列表。

void proxy_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e) 
{ 
    Stream stream = new MemoryStream(Encoding.Unicode.GetBytes(e.Result)); 

    DataContractJsonSerializer obj = new DataContractJsonSerializer(typeof(List<Student>)); 
    List<Student> result = obj.ReadObject(stream) as List<Student>; 
    lstStudents.ItemsSource = result; 
}

您应该标记所有类和属性DataContract和DataMember属性。使用你的代码片段，我创建这样的事情：

[DataContract] 
    public class Result 
    { 
     [DataMember(Name="responseCode")] 
     public int Code { get; set; } 

     [DataMember(Name="responseObject")] 
     public ResponseObject Result { get; set; } 
    } 

    [DataContract] 
    public class ResponseObject 
    { 
     [DataMember] 
     public int TotalRecords { get; set; } 

     [DataMember] 
     public int TotalDisplayRecords { get; set; } 

     [DataMember(Name="aaData")] 
     public DataItem[] Data { get; set; } 
    } 

    [DataContract] 
    public class DataItem 
    { 
     [DataMember(Name = "InvoiceId")] 
     public int InvoiceId { get; set; } 

     // Others properties 
    }
