反序列化嵌套json字符串

我的json数据是这样的

"{'"total_entries'":2,'"current_page'":1,'"total_pages'":1,'"per_page'":2,'"items'":[{'"workspace'":{'"background_color'":'"#ffedd3'",'"data_room'":false,'"default_sort'":'"alphabetical'",'"default_view'":'"list'",'"id'":330201,'"name'":'"MyWorkSpaceNew'",'"updated_at'":'"2013-05-08T05:54:25-07:00'",'"root_folder_id'":166325721,'"owner_id'":991101,'"is_owner'":true,'"effective_role'":'"Administrator'",'"audit_trail'":true,'"require_agreement'":false,'"agreement_accepted'":false}},{'"workspace'":{'"background_color'":'"white'",'"data_room'":false,'"default_sort'":'"alphabetical'",'"default_view'":'"list'",'"id'":343316,'"name'":'"qqq'",'"updated_at'":'"2013-05-12T22:34:08-07:00'",'"root_folder_id'":179855446,'"owner_id'":991101,'"is_owner'":true,'"effective_role'":'"Administrator'",'"audit_trail'":true,'"require_agreement'":false,'"agreement_accepted'":false}}]}"

我想反序列化json数据我的c#代码就像

workspacename data = new System.Web.Script.Serialization.JavaScriptSerializer().Deserialize<workspacename>(responseText);

我想要反序列化的数据，我得到的total_entries，项目计数，per_page，但在工作空间内，我得到的一切都是null

 public class workspacename
{
    public int total_entries { get; set; }//getting value
    public int current_page { get; set; }//getting value
    public int total_pages { get; set; }//getting value
    public int per_page { get; set; }//getting value
    public List<items> items { get; set; }// items count 2 but value null.
}
public class items
{
   // public List<workspace> workspace { get; set; }
    public string background_color { get; set; }
    public bool data_room { get; set; }
    public string default_sort { get; set; }
    public string default_view { get; set; }
    public int id { get; set; }
    public string name { get; set; }
    public DateTime updated_at { get; set; }
    public int root_folder_id { get; set; }
    public int owner_id { get; set; }
    public bool is_owner { get; set; }
    public string effective_role { get; set; }
    public bool audit_trail { get; set; }
    public bool require_agreement { get; set; }
    public bool agreement_accepted { get; set; }
}

反序列化嵌套json字符串

使用DataContractJsonSerializer:

你应该用属性定义你的数据类:

[DataContract]
public class workspacename
{
    [DataMember]
    public int total_entries { get; set; }//getting value
    [DataMember]
    public int current_page { get; set; }//getting value
...

和

[DataContract]
public class items
{
    [DataMember]
    public string background_color { get; set; }
    [DataMember]
    public bool data_room { get; set; }
...

那么反序列化你的json对象，你应该:

var serializer = new DataContractJsonSerializer(typeof(workspacename));
using (var stream = new MemoryStream())
{
 var asBytes = Encoding.UTF8.GetBytes(jsonObjectString);
 stream.Write(asBytes, 0, asBytes.Length);
 stream.Flush();
 stream.Seek(0, SeekOrigin.Begin);
 var yourDeserializedWorkspacename= (workspacename)serializer.ReadObject(stream);
}

对于Newtonsoft.Json，这很简单:

workspacename obj = JsonConvert.DeserializeObject<workspacename>(inputJson)

值得注意的是，最好遵守命名约定:

workspacename => WorkSpaceName
total_entries => TotalEntries
