JSONファイルから最後の "日付"を取得するにはどうすればよいですか？

Question

私はJSONファイルを持っています。ファイル内のエントリが順不同である可能性があります。

最後のカレンダーの日付入力はどのようにして取得できますか？

JSONファイルには、日付のパターンのみが、それは常に月曜日になるということですLINQ を使用して見つけるの簡単な方法がある場合は私に知らせてください

あなたの質問をファイル、これは推測のようなものです。あなたの質問が更新され、JSON処理自体について実際には、私はおそらくこの答えを削除します。私はあなたが何とかこれに類似したオブジェクトのリストにあなたのJSONを処理していると仮定するつもりです

：

public class ScheduleEntry 
{ 
    public string Name 
    { 
     get; 
     set; 
    } 

    public DateTime DateStamp 
    { 
     get; 
     set; 
    } 

    // Plus the rest of the properties 
} 

を使用すると、処理方法のいくつかの種類を持っていると仮定すると、あなたは、単にこのような何かを持っているでしょう。

private void ProcessSchedule() 
{ 
    List<ScheduleEntry> scheduleList = new List<ScheduleEntry>(); 

    // [Processing from JSON Done Here] 

    // [Done Processing] 

    DateTime maxDate = scheduleList.Max(o => o.DateStamp); 
}
