反序列化json時獲取null
[英]getting null while deserialization json
問題描述
我正在嘗試將我的網絡響應json反序列化為一個對象，當時反序列化之后對象變為null 。 這是我的代碼：
JSON響應：

public List<Attendee> Attendees { get; set; }
public object Recurrence { get; set; }
public Organizer Organizer { get; set; }
public string iCalUId { get; set; }
}
反序列化：
JavaScriptSerializer json = new JavaScriptSerializer();
value condiiton = (value)json.Deserialize(responcedata, typeof(value));

讓我們看一下您的JSON對象。 實際上，您有一個帶有兩個對象的匿名JSON對象（我們稱其為response ）：字符串'@ odata.context'和value C＃類類型的對象的數組'value'。
您已經描述了value類，但是現在您嘗試將response對象反序列化為不正確的value 。
您需要描述相應的類並將其反序列化。
public class Response
{
public value[] value { get; set; }
}
然后，您可以通過以下方式進行操作：
JavaScriptSerializer json = new JavaScriptSerializer();
Response response = (Response)json.Deserialize(responcedata, typeof(Response));
json反序列化返回null
