Question

我有一个跟踪参与者，当被调用时，会触发一个新线程来执行跟踪工作。跟踪工作最终会这样做：

private static readonly ConcurrentDictionary<string, DateTime> TimingsDictionary = new ConcurrentDictionary<string, DateTime>();
private static readonly ConcurrentDictionary<Guid, DateTime> WorkflowTimingsDictionary = new ConcurrentDictionary<Guid, DateTime>();

private void TimeActivityRecord(TrackingRecord record)
{
    var activityStateRecord = record as ActivityStateRecord;
    if (activityStateRecord != null)
    {
        if (activityStateRecord.State == ActivityStates.Executing)
        {
            if (!TimingsDictionary.TryAdd(GetActivityId(activityStateRecord), activityStateRecord.EventTime))
            {}
        }

        if (activityStateRecord.State == ActivityStates.Closed
            || activityStateRecord.State == ActivityStates.Faulted
            || activityStateRecord.State == ActivityStates.Canceled)
        {
            DateTime startTime;
            if (TimingsDictionary.TryRemove(GetActivityId(activityStateRecord), out startTime))
            {
                timer.TimeAction("Executing workflow step " + activityStateRecord.Activity.Name, activityStateRecord.InstanceId, activityStateRecord.EventTime.Subtract(startTime));
            }
        }
    }
}

private void TimeWorkflowRecords(TrackingRecord record)
{
    var workflowInstanceRecord = record as WorkflowInstanceRecord;
    if (workflowInstanceRecord != null)
    {
        if (workflowInstanceRecord.State == WorkflowInstanceStates.Started)
        {                    
            if (!WorkflowTimingsDictionary.TryAdd(workflowInstanceRecord.InstanceId, workflowInstanceRecord.EventTime))
            {}
        }

        if (workflowInstanceRecord.State == WorkflowInstanceStates.Completed
            || workflowInstanceRecord.State == WorkflowInstanceStates.Aborted
            || workflowInstanceRecord.State == WorkflowInstanceStates.UnhandledException
            || workflowInstanceRecord.State == WorkflowInstanceStates.Terminated
            || workflowInstanceRecord.State == WorkflowInstanceStates.Canceled)
        {
            DateTime startTime;
            if (WorkflowTimingsDictionary.TryRemove(workflowInstanceRecord.InstanceId, out startTime))
            {
                timer.TimeAction("Executing workflow", workflowInstanceRecord.InstanceId, workflowInstanceRecord.EventTime.Subtract(startTime));
            }
        }
    }
}

跟踪整个工作流程时间和已配置活动的时间。但是我得到了奇怪的结果，工作流实例本身似乎总是比最长的活动花费更少的时间。有时我的工作流程需要16毫秒，其中的6个活动需要625毫秒，150毫秒，125毫秒，93毫秒，17毫秒，78毫秒。

我做错了什么吗？我觉得我必须错过一些非常明显的东西，但不能为我的生活看到它是什么。

Answer 1

当然我做了一些愚蠢的事。当我记录从我使用的时间跨度中取出的时间

timespan.Milliseconds

而不是

timespan.TotalMilliseconds

回到学校。或者也许只是睡一觉。

在跟踪我的工作流程时，为什么会出现奇怪的时间？
