我已经在这里和其他网站上的解决此问题的浏览相当多的线程。

I've browsed quite a few threads on here and on other sites for solutions to this problem.

下面是我的FileMonitor类：

Here's my FileMonitor class:

class FileMonitor
{
    public FileMonitor(String path)
    {
        try
        {
            var watcher = new FileSystemWatcher()
            {
                Path = path,
                IncludeSubdirectories = true,
                InternalBufferSize = 65536,
                EnableRaisingEvents = true
            };

            watcher.Changed += new FileSystemEventHandler(OnFileChanged);
            watcher.Created += new FileSystemEventHandler(OnFileCreated);
            watcher.Deleted += new FileSystemEventHandler(OnFileDeleted);
            watcher.Renamed += new RenamedEventHandler(OnFileRenamed);
            watcher.Error += new ErrorEventHandler(OnWatcherError);
        }
        catch (Exception)
        {

            throw;
        }
    }

    private void OnWatcherError(object sender, ErrorEventArgs e)
    {

    }

    private void OnFileChanged(object sender, FileSystemEventArgs e)
    {
        try
        {
            ((FileSystemWatcher)sender).EnableRaisingEvents = false;

            LogFileSystemChanges(e);
        }

        finally
        {
            ((FileSystemWatcher)sender).EnableRaisingEvents = true;
        }
    }

    private void OnFileCreated(object sender, FileSystemEventArgs e)
    {
        try
        {
            ((FileSystemWatcher)sender).EnableRaisingEvents = false;

            LogFileSystemChanges(e);
        }

        finally
        {
            ((FileSystemWatcher)sender).EnableRaisingEvents = true;
        }
    }

    private void OnFileDeleted(object sender, FileSystemEventArgs e)
    {
        try
        {
            ((FileSystemWatcher)sender).EnableRaisingEvents = false;

            LogFileSystemChanges(e);
        }

        finally
        {
            ((FileSystemWatcher)sender).EnableRaisingEvents = true;
        }
    }

    private void OnFileRenamed(object sender, RenamedEventArgs e)
    {
        try
        {
            ((FileSystemWatcher)sender).EnableRaisingEvents = false;

            LogFileSystemRenaming(e);
        }

        finally
        {
            ((FileSystemWatcher)sender).EnableRaisingEvents = true;
        }
    }

    private void LogFileSystemChanges(FileSystemEventArgs e)
    {
        string log = string.Format("{0:G}: {1} | {2}", DateTime.Now, e.FullPath, e.ChangeType);
        Console.WriteLine(log);
    }

    private void LogFileSystemRenaming(RenamedEventArgs e)
    {
        string log = string.Format("{0:G}: {1} | Old name: {2}", DateTime.Now, e.FullPath, e.OldName);
        Console.WriteLine(log);
    }
}

正如你所知道的，我已经尝试了锁定的（（FileSystemWatcher的）发件人）.EnableRaisingEvents = FALSE; ，但我可以告诉我的控制台输出我事件触发两次。

As you can tell, I have tried the "lock" of ((FileSystemWatcher)sender).EnableRaisingEvents = false;, but I can tell from my console output my events are triggering twice.

对此有何想法？我真的不知道在哪里何去何从。

Any ideas on this? I'm really not sure where to go from here.

推荐答案

我有同样的问题，之后无事生非得出的结论是的记事本的将文件写入三次（！）的行。如果一个应用程序确实节省了很多经常（也许到三角备份等等）也没有什么可以做。

I've had the same problem and after much ado came to the conclusion that Notepad writes a file three times (!) in row. If an app really saves that much often (maybe to triangulate backups and such) there isn't much you can do.

我也注意到你已经连接到所有的事件，你应该范围缩小到你所需要的最少，过滤掉那些你不与NotifyFilters.

I also noticed you have attached to all events, you should narrow it down to the least you need and filter out those you aren't interested in with the NotifyFilters.
