如何從RootObject解析Json？

Question

我想解析JSON響應，所以我創建了一些類。

其實我想腿部和航班類元素值。我試圖從RootObject得到那些元素值，但我不知道如何做到這一點。我用Google搜索了一下，但我有點困惑。

我粘貼我的JSON respose，Classes !!

JSON響應：

{ 
public string kind { get; set; } 
public string requestId { get; set; } 
public Data data { get; set; } 
public List<TripOption> tripOption { get; set; } 
} 

public class RootObject 
{ 
public string kind { get; set; } 
public Trips trips { get; set; } 
} 

代碼：

 var obj0 = JsonConvert.DeserializeObject<RootObject>(responsedata); 

在這裏，我只拿到了Trip類元素。我需要Leg和Flight類元素。

如果您想查找特定腿的信息，則需要使用Linq來遍歷樹。例如，如果您只知道腿ID，則可以這樣做：

var allLegs = obj0.trips.tripOption.SelectMany(to => to.slice.SelectMany(sl => sl.segment.Select(sg => sg.leg))); 

var leg = allLegs.FirstOrDefault(l => l.id == "yourId"); 

檢索航班的查詢類似。您還可以通過tripOption ID進行過濾，以獲取特定的tripOption，然後檢索與其關聯的航班或航段。
