  How to deserialize a JSON string from facebook in asp.net?

  Feb 19, 2012 01:31 AM|vinikatyal|LINK

  I am having real hard time trying to deserialize this JSON string where in i want to extract the user's work_history, current_location and education_history

  My string is a as follows:

  {"uid":56354665,"name":"ABCBGFF","pic_square":"https:\/\/fbcdn-profile-a.akamaihd.net\/hprofile-ak-snc4\/370835_520310824_553662476_q.jpg","affiliations":[],"birthday_date":"12\/03\/1986","sex":"female","relationship_status":null,"current_location":{"city":"Delhi","state":"Delhi","country":"India","zip":"","id":102161913158207,"name":"Delhi, India"},"education_history":[{"name":"I E T , Alwar (Raj.)","year":2007,"concentrations":[],"school_type":"College"},{"name":"Institute of Engineering and Technology, Alwar","concentrations":[],"school_type":"College"}], "work_history":[{"location":{"city":"","state":""},"company_name":"Defence Research & Development Organisation (DRDO)","description":"","start_date":"0000-00","end_date":"0000-00"}],"contact_email":null} ,
  {"uid":522036860,"name":"ABCPRE","pic_square":"https:\/\/fbcdn-profile-a.akamaihd.net\/hprofile-ak-snc4\/174460_522036860_1780781144_q.jpg","affiliations":[],"birthday_date":"12\/07","sex":"female","relationship_status":null,"current_location":{"city":"New Delhi","state":"Delhi","country":"India","zip":"","id":106517799384578,"name":"New Delhi, India"},"education_history":[{"name":"Amity University","concentrations":["Event Management","Journalism & Mass Communication","Advertising"],"school_type":"College"},{"name":"Amity University","year":2009,"concentrations":["Journalism and Mass Communication"],"school_type":"College"},{"name":"Amity School of Communication","concentrations":[],"school_type":"College"}],"work_history":[{"location":{"city":"","state":""},"company_name":"- \/ as a photographer! :D","description":"","start_date":"0000-00"},{"location":{"city":"","state":""},"company_name":"Infinity Advertising Services Pvt. Ltd.","description":"","start_date":"0000-00","end_date":"0000-00"}],"contact_email":null }

  My Class is as follows :

  public class Data
  {
  public List<CurrentLocation> current_location { get; set; }
  public List<WorkHistory> work_history { get; set; }
  public List<EducationHistory> education_history { get; set; }
  }
  
  public class EducationHistory
  {
  public string name { get; set; }
  public int? year { get; set; }
  public string school_type { get; set; }
  }
  
  public class WorkHistory
  {
  public string company_name { get; set; }
  public Location location { get; set; }
  }
  
  public class CurrentLocation
  {
  public string city { get; set; }
  public string state { get; set; }
  public string country { get; set; }
  }
  
  public class Location
  {
  public string city { get; set; }
  public string state { get; set; }
  }

  How do i retreive and display values currently its showing null values 

  when i try this :
  
  
  
   Data soap = JsonConvert.DeserializeObject<Data>(ser);

  HI,

  You can call overloaded method of DeserializedObject as 

  DeserializeObject<T>(string value, JsonSerializerSettings settings);

  and set setting as (whichever is your case, null handling, default value etc)

   JsonSerializerSettings setting = new JsonSerializerSettings();
  setting.DefaultValueHandling = DefaultValueHandling.Ignore;
  setting.MissingMemberHandling = MissingMemberHandling.Ignore;
  setting.NullValueHandling = NullValueHandling.Include;

  and call 

  JsonConvert.DeserializeObject<Data>(ser,setting); method

  serialization Json
