無法將此JSON反序列化為C＃對象

Question

我有此JSON，並想將其反序列化為C＃中的對象。 請注意，數據字段看起來像字典。

{
  "responseID": "LTg5MjUyNDgxMDgyNzU3NjgyNDMtMjAxNi0wNS0xOFQxOTo1ODoxOS45ODFaLTk4MTAwMDAwMA==",
  "timestamp": "2016-05-18T19:58:19.981Z",
  "type": "v0.1-reject-reason-codes",
  "context": {
    "tenant": "hpho"
  },
  "data": {
    "LOST_TO_COMPETITOR": "Lost to Competitor",
    "OTHER": "Other (see notes)",
    "DISCONTINUED": "Product Discontinued",
    "SERVICE_ISSUES": "Service Issues",
    "SEASONAL": "Seasonal Fluctuations"
  }
}

這是類的定義

public static class JSONConstants
    {
        public const string responseID = "responseID";
        public const string timestamp = "timestamp";
        public const string type = "type";
        public const string context = "context";
        public const string data = "data";
        public const string tenant = "tenant";
    }

    [DataContract]
    public class RejectReasonCodesResponse
    {
        [DataMember(Name = JSONConstants.responseID)]
        public string ResponseID { get; set; }
        [DataMember(Name = JSONConstants.timestamp)]
        public string Timestamp { get; set; }
        [DataMember(Name = JSONConstants.type)]
        public string Type { get; set; }
        [DataMember(Name = JSONConstants.context)]
        public SummaryContext Context { get; set; }
        [DataMember(Name = JSONConstants.data)]
        public Dictionary<string, string> Data { get; set; }
    }

    [DataContract]
    public class SummaryContext
    {
        [DataMember(Name = JSONConstants.tenant)]
        public string Tenant { get; set; }
    }

這就是我反序列化的方式

string requestURL = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";

                HttpWebRequest request = WebRequest.Create(requestURL) as HttpWebRequest;
                request.Headers["Ocp-Apim-Subscription-Key"] = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxx";

                HttpWebResponse response = (HttpWebResponse)request.GetResponse();

                if (response.StatusCode != HttpStatusCode.OK
                 && response.StatusCode != HttpStatusCode.NonAuthoritativeInformation)
                    throw new Exception(String.Format(
                        "Server error (HTTP {0}: {1}).",
                        response.StatusCode,
                        response.StatusDescription));

                DataContractJsonSerializer jsonSerializer = new DataContractJsonSerializer(typeof(RejectReasonCodesResponse));
                object objResponse = jsonSerializer.ReadObject(response.GetResponseStream());

但是，objResponse中的“數據”字段為空。 我做錯了什么？

Answer 1

您可以驗證您的類定義嗎？ 我認為應該看起來像這樣。

public class SummaryContext
{
    public string tenant { get; set; }
}

public class Data
{
    public string LOST_TO_COMPETITOR { get; set; }
    public string OTHER { get; set; }
    public string DISCONTINUED { get; set; }
    public string SERVICE_ISSUES { get; set; }
    public string SEASONAL { get; set; }
}

public class RejectReasonCodesResponse
{
    public string responseID { get; set; }
    public string timestamp { get; set; }
    public string type { get; set; }
    public Context context { get; set; }
    public Data data { get; set; }
}

而是嘗試像這樣使用javascriptserializer

javascriptserializer js = new javascriptserializer();
var response = js.Deserialize<RejectReasonCodesResponse>(jsonstring);

首先，使用json.lint之類的站點來填充JSON。 當綠色（如果有）進入Visual Studio並粘貼特殊對象時，可以將json作為類粘貼。 網站Json2csharp也很有用。
