गहरा घोंसला वाले जेसन ऑब्जेक्ट से डेटा प्राप्त करना

Question

मैं वास्तव में 2 दिनों के लिए इस समस्या पर फंस गया हूं, मैं गहरा घोंसला वाले जेसन ऑब्जेक्ट से डेटा कैसे प्राप्त कर सकता हूं।

मुझे एक ऑनलाइन जेसन उपकरण http://www.jsoneditoronline.org/http://jsonformat.com/ मिला है, जब आप अपने जेसन को पेस्ट करते हैं, तो सभी ऑब्जेक्ट एरे आदि दिखाते हैं, इसलिए मैं डेटा में खोद सकता हूं और जो जानकारी चाहता हूं उसे प्राप्त कर सकता हूं।

जब मैं कोड डीबग करता हूं और ब्रेक पॉइंट डालता हूं: foreach (JToken data in rates.ToArray()) मैं डेटा देख सकता हूं, मैं बस डेटा प्राप्त नहीं कर सकता, मैं जो कोशिश करता हूं उस पर निर्भर करता है कि मुझे जो त्रुटि मिलती है, उस पर निर्भर करता है, पिछली त्रुटि थी ।

मूल्य कनवर्ट करने में त्रुटि "@rateChange" टाइप करने के लिए 'Web.UI.Controllers.HomeController + RateInfo'।

सिस्टम से कस्ट या कनवर्ट नहीं किया जा सका। स्ट्रिंग से Web.UI.Controllers.HomeController + RateInfo।

इसके साथ किसी भी मदद की बहुत सराहना की जाती है।

public class RateInfo 
     { 
      public string RateChange { get; set; } 
      public string Promo { get; set; } 
      public string PriceBreakdown { get; set; } 
      public bool NonRefundable { get; set; } 
      public string RateType { get; set; } 
      public int CurrentAllotment { get; set; } 
      public int? PromoId { get; set; } 
      public string PromoDescription { get; set; } 
      public string PromoType { get; set; } 
     } 

कोड

IList<JToken> rates = root["HotelListResponse"]["HotelList"]["HotelSummary"][0]["RoomRateDetailsList"]["RoomRateDetails"]["RateInfos"]["RateInfo"].Children().ToList(); 


         IList<RateInfo> info = new List<RateInfo>(); 
         foreach (JToken data in rates.ToArray()) 
         { 
          RateInfo rateInfo = JsonConvert.DeserializeObject<RateInfo>(data.ToString()); 
          info.Add(rateInfo); 
         }

Answer 1

की जरूरत नहीं मिल सकता है इस के बजाय का प्रयास करें:

IList<JToken> rates = root["HotelListResponse"]["HotelList"]["HotelSummary"][0]["RoomRateDetailsList"]["RoomRateDetails"]["RateInfos"].Children().ToList(); 

संपादित करें:

var rateInfo = json["HotelListResponse"]["HotelList"]["HotelSummary"][0]["RoomRateDetailsList"]["RoomRateDetails"]["RateInfos"]["RateInfo"]; 

var result =JsonConvert.DeserializeObject<RateInfo>(rateInfo .ToString()); 

Answer 2

इस विस्तार विधि एक गहरी घोंसले जेसन के माध्यम से लूप के लिए रिकर्सन का उपयोग करता है और एक जेप्रोपर्टी के लिए मूल्य पाता है।

 public static TType JsonValue<TType>(this JObject obj, string key) 
    { 
     object result = null; //default to null if nothing is found 

     foreach (var item in obj) 
     { 
      var token = item; 

      if (token.Key.Equals(key, StringComparison.InvariantCultureIgnoreCase)) 
      { 
       result = token.Value.ToObject<TType>(); //return the value found 
       break; 
      } 

      if (!obj[token.Key].Children().Any()) 
       continue; 

       var jt = obj[token.Key].ToString(); 

       if (!jt.StartsWith("[")) 
       { 
        result = JsonValue<TType>(JObject.Parse(jt), key); 
       } 
       else 
       { 
        obj[token.Key].Children().ToList().ForEach(x => 
        { 
         //only the first match will be returned 
         result = JsonValue<TType>(JObject.Parse(x.ToString()), key); 
        }); 
       } 

      if (result != null) 
       break; 

     } 

     return (TType)result; 
    } 

उपयोग कैसे करें:

var myValue = jsonObject.JsonValue<string>("propName"); 
    var numbValue = jsonObject.JsonValue<long?>("propName2") ?? 0;
