我需要一个帮助来编写一个linq查询，以便根据EventType Keypress事件执行groupby，并获取花费的总时间

我对你的课程做了两个小改动：

我将EventType更改为string，因为我不想实现您的枚举

我已将“EventTime”更改为类型

DateTime

。这样，我就不必尝试将字符串解析为查询中的日期

对此，我使用了该查询：

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();

var data=new JavaScriptSerializer（）。反序列化（File.ReadAllText（@“C:\users\foo\desktop\demo.json”）//在本地保存数据
其中（x=>x.EventType==“5”）//5是按键
.GroupBy（d=>d.ProcessName）//按ProcessName分组
.选择（d=>new{
ProcessName=d.FirstOrDefault（）.ProcessName，
//获取最大值；减去最小值；以秒为单位获取大致的持续时间
持续时间=d.Max（x=>x.EventTime）-d.Min（x=>x.EventTime），
//将所有刻度相加，以获得以刻度为单位的持续时间
DurationTicks=d.Sum（x=>x.LongEventTime）
})
//林帕德本地人；不要在Visual Studio或VS代码中使用
.Dump（）；

输出：

Hey@ravi你能提供保存数据集的类吗？是

LongEventTime

以毫秒为单位的时间还是滴答声？LongEventTime是滴答声..在哪个命名空间上可以找到

EventType

类？EventType是我的内部枚举，可能是左键单击、右键单击、按键、复制粘贴等。不，除非你告诉我，什么不起作用。我看不见你的脑袋或电脑屏幕。
