知道Windows 8上文件何时更改 [英] Know when a file changes on windows 8

问题描述

我知道FileSystemWatcher类在Windows 8上不起作用.

I know that the class FileSystemWatcher does not work on windows 8. Why are FileSystemWatcher Attribute changes detected on Windows 7 but not Windows 8?

无论如何，我都需要知道目录中文件的更改时间.例如，我在计算机上安装了保管箱，当我更新文件时，它开始同步. Dropbox如何知道Windows 8中文件的更改时间?

Anyways I need to know when a file is changed within a directory. For example I have dropbox installed on my computer and the moment I update a file it starts synchronizing. How does dropbox knows when a file has changed in windows 8?

我已经在c ++中尝试过此解决方案 http://msdn.microsoft.com/zh-cn/library/aa365261 ，我遇到的问题与FileSystemWatcher相同.问题似乎出在Windows 8而不是类FileSystemWatcher. 我可以采取什么解决方案?

I already tried this solution in c++ http://msdn.microsoft.com/en-us/library/aa365261 and I have the same problem as FileSystemWatcher. The problem seems to be from windows 8 instead of the class FileSystemWatcher. What work around solution can I take?

推荐答案

这是我在等待新dll编译然后将其复制到目标文件夹之前使用的一些代码，它似乎可以正常工作.

Here's some code I've used before to wait for a new dll to be compiled and then copy it to some target folder, and it seems to work okay.

static void StartWatching(string path)
{
    var watcher = new FileSystemWatcher();
    watcher.Path = path;
    watcher.NotifyFilter = NotifyFilters.LastAccess | NotifyFilters.LastWrite | NotifyFilters.FileName |
                           NotifyFilters.DirectoryName;
    watcher.Changed += watcher_Created;
    watcher.Created += watcher_Created;
    watcher.EnableRaisingEvents = true;

    var copier = new Thread(ConsumeOutOfTheFilesToCopyQueue);
    copier.Start();
}

    static void watcher_Created(object sender, FileSystemEventArgs e)
    {
        if (e.Name.Contains("whatever.dll"))
            if (!_filesToCopy.Contains(e.FullPath))
                lock (_syncRoot)
                    if (!_filesToCopy.Contains(e.FullPath))
                        _filesToCopy.Enqueue(e.FullPath);
    }
