linqのイベントタイプに基づいてgroupbyを実行

Question

私は、スクリーンショットですべてのユーザーアクティビティを追跡するアプリケーションを持っています。私は問題を抱えているのですが、報告するうちに、ユーザーが特定の分野のキープレスイベントにどれくらいの時間を費やしているかを知りたいと思っています。 ここにサンプルデータがあります。

public class UserActivityData 
    { 
     [DisplayName("Process Name")] 
     public string ProcessName { get; set; } 
     [DisplayName("Window Title")] 
     public string WindowTitle { get; set; } 
     [DisplayName("Event Type")] 
     public EventType EventType { get; set; } 
     [DisplayName("Event Time")] 
     public string EventTime { get; set; } 
     [DisplayName("Total Time Spent In Secs")] 
     public string TotalTimeSpent { get; set; } 
     public int X { get; set; } 
     public int Y { get; set; } 
     [DisplayName("Capture Data")] 
     public string CaptureData { get; set; } 
     public string ApplicationPath { get; set; } 
     [DisplayName("Element Name")] 
     public string ElementName { get; set; } 
     [DisplayName("Automation ID")] 
     public string AutomationID { get; set; } 
     [DisplayName("Control Type")] 
     public string ControlType { get; set; } 
     public long LongEventTime { get; set; } 
    } 


public enum EventType 
    { 
    RightClick, 
    LeftClick, 
    MiddleButton, 
    MouseMove, 
    DoubleClick, 
    KeyPress, 
    Copy, 
    Paste, 
    Focus, 
    Open, 
    Close, 
    FiddlerRequest 
} 

これは、データセットを保持するクラスです。

私は、イベントタイプKeyPressイベントに基づいてGROUPBYを行うためにLINQクエリを記述し、費やした時間の合計を取得するための助けが必要。

Answer 1

私はあなたのクラスに2つの小さな変更を行わ：私はあなたの列挙を実装したくなかったので、私は、文字列にイベントタイプを変更し

1. を。
2. "EventTime"をタイプDateTimeに変更しました。この方法では、クエリで文字列を日付に解析する必要はありません。私はそのクエリを使用して、この

：

var data = new JavaScriptSerializer().Deserialize<List<UserActivityData>>(File.ReadAllText(@"C:\users\foo\desktop\demo.json")); //saved your data locally 
data.Where(x => x.EventType == "5") // 5 is KeyPress 
    .GroupBy(d => d.ProcessName) //Grouping by ProcessName 
    .Select (d => new { 
     ProcessName = d.FirstOrDefault().ProcessName, 
     //get Max; substract min; get rough duration in seconds 
     Duration = d.Max (x => x.EventTime) - d.Min (x => x.EventTime), 
     //sum up all ticks to get duration in ticks 
     DurationTicks = d.Sum (x => x.LongEventTime) 
    }) 
    //LinqPad native; do not use in Visual Studio or VS Code 
    .Dump();
