我如何从另一个刻度中减去刻度

Question

结果如下:

从会话

中获取loginstart的定时句柄

var markStored = PPSession.TimingMarks["loginstart"];

get ticks from utcnow

var markNow = PPSession.TimingMarks["loginstart"] 
    = new TimingMark { endTime = DateTime.UtcNow.Ticks };

并且想要从存储的刻度中减去电流

diff = markStored - markNow;

Answer 1

最后一行有几个问题:

1. 首先，markNow是TimingMark，所以除非您覆盖了-操作符，否则您应该指定其中的属性是您想要用于执行-操作的属性(否则就像说object - object)
2. 和上面一样-同样对于你的markStored，你应该指定你想要做-的时间属性

:

var diff = markStored.timeField.Ticks - markNow.endTime;

和存根数据:

var markStored = new { Time = DateTime.Now };
var markNow = new { endTime = DateTime.UtcNow.Ticks };
var diff = markStored.Time.Ticks - markNow.endTime;
