Filesystemwatcher 不监视子目录

Question

我正在尝试使用 docker 卷中的 FileSystemWatcher 监视文件夹中的所有文件 created/deleted/renamed。它正在获取正在监视的根目录（大部分时间）上的事件，但即使 IncludeSubdirectories = true，subdir 中也没有任何事件触发事件。观察者被保存为道具。我怎样才能让它观看子目录并触发所有事件，而不仅仅是大多数事件？

    public void StartMonitorService()
    {
        Watcher = new FileSystemWatcher(@"/var/lib/docker/volumes/monitor");
        Watcher.NotifyFilter = NotifyFilters.Attributes
                             | NotifyFilters.CreationTime
                             | NotifyFilters.DirectoryName
                             | NotifyFilters.FileName
                             | NotifyFilters.LastAccess
                             | NotifyFilters.LastWrite
                             | NotifyFilters.Security
                             | NotifyFilters.Size;

        Watcher.Created += OnCreated;
        Watcher.Deleted += OnDeleted;
        Watcher.Renamed += OnRenamed;

        Watcher.Filter = "";
        Watcher.IncludeSubdirectories = true;
        Watcher.EnableRaisingEvents = true; 
    }

我没有完全解决我的问题，但对于可能遇到与我相同的问题的任何人，我都有解决办法。

private void OnCreated(object sender, FileSystemEventArgs e)
{
    if (Directory.Exists(e.FullPath))
    {
        string dirRoot = e.FullPath;
        DateTime lastTimeWriten = Directory.GetLastWriteTime(dirRoot);
        while (true)
        {
            Thread.Sleep(30000);
            if (lastTimeWriten == Directory.GetLastWriteTime(dirRoot))
                break;

            lastTimeWriten = Directory.GetLastWriteTime(dirRoot);
        }
        HashSet<string> fileSet = new HashSet<string>(Directory.GetFileSystemEntries(dirRoot, "*", SearchOption.AllDirectories));
        ...
        _messageService.SendNewSurveyMessage(newSurveyFileSet);
    }
}
