JSON文字列をJsonConvertで解析する＃

Question

外部WebサービスからJSON文字列を取得します。私はevents配列のイベントをデータベースに保存したいと思います。 List<FacebookEvents>を取得するにはどうすればよいですか？

私の現在の試みは動作しません： List<FacebookEvents> my_obj = JsonConvert.DeserializeObject <FacebookEvents> (jsonString);

ソースJSONを：あなたが定義するために不足している

Answer 1

あなたList<Event>とMetadata含まれていRootObject。 Full Example

public class RootObject 
{ 
    public List<Event> events { get; set; } 
    public Metadata metadata { get; set; } 
} 

public class Stats 
{ 
    public int attending { get; set; } 
    public int declined { get; set; } 
    public int maybe { get; set; } 
    public int noreply { get; set; } 
} 

public class Location 
{ 
    public string city { get; set; } 
    public string country { get; set; } 
    public double latitude { get; set; } 
    public double longitude { get; set; } 
    public string state { get; set; } 
    public string street { get; set; } 
    public string zip { get; set; } 
} 

public class Venue 
{ 
    public string id { get; set; } 
    public string name { get; set; } 
    public string coverPicture { get; set; } 
    public string profilePicture { get; set; } 
    public Location location { get; set; } 
} 

public class Event 
{ 
    public string id { get; set; } 
    public string name { get; set; } 
    public string coverPicture { get; set; } 
    public string profilePicture { get; set; } 
    public string description { get; set; } 
    public string distance { get; set; } 
    public string startTime { get; set; } 
    public int timeFromNow { get; set; } 
    public Stats stats { get; set; } 
    public Venue venue { get; set; } 
} 

public class Metadata 
{ 
    public int venues { get; set; } 
    public int venuesWithEvents { get; set; } 
    public int events { get; set; } 
} 

これは動作します：

var result = JsonConvert.DeserializeObject<RootObject>(jsonString); 

EDIT：

を第一に、これはあなたが会場の情報を取ることができますどのようにここでは、JSONです。

foreach(var item in result.events) 
{ 
    Console.WriteLine(item.venue.name); 
} 

Answer 2

あなたは、コレクションに

public class RootObject { 

    public IList<FacebookEvents> events {get;set;} 

} 

を格納するために、次にあなたがイベント

var root = JsonConvert.DeserializeObject<RootObject>(jsonString); 
var events = root.events;
