FileSystemWatcher不会使用'mv'命令检测移动到目录中的文件，也不会在ubuntu上剪切和粘贴

Posted 2021-04-04

我正在使用FileSystemWatcher来检测放入目录的文件，然后将它们转发到别处并从目录中删除。在开发期间，我只是将文件复制到目录中进行测试，但是我只是意识到没有事件在qa中被触发，因为文件被移动，而不是复制到目录中。有没有办法在ubuntu上使用c＃dotnet core捕获移动到目录中的文件？

下面是我的代码的摘录，显示我如何设置观察者，在我的实际应用程序中，我只是观看已更改的事件，但添加了更多事件监听器以尝试找出如何执行此操作

    CaptureServerSettings appSettings = provider.GetRequiredService<CaptureServerSettings>();

    using (FileSystemWatcher directoryWatcher = new FileSystemWatcher(appSettings.WatchDirectory, "*.*"))
    {
        directoryWatcher.BeginInit();
        directoryWatcher.IncludeSubdirectories = false;
        directoryWatcher.NotifyFilter = NotifyFilters.LastWrite;
        directoryWatcher.Error += errorEvent;
        directoryWatcher.Renamed += renameEvent;
        directoryWatcher.Created += createdEvent;
        directoryWatcher.Changed += changedEvent;
        directoryWatcher.EnableRaisingEvents = true;
        directoryWatcher.EndInit();
        provider.GetRequiredService<CancellationTokenSource>().Token.WaitHandle.WaitOne();
        }

    private static void changedEvent(object sender, FileSystemEventArgs e) => _logger.LogWarning("Changed: {@eventargs}", e);

    private static void errorEvent(object sender, ErrorEventArgs e) => _logger.LogWarning("Error: {@eventargs}", e);

    private static void createdEvent(object sender, FileSystemEventArgs e) => _logger.LogWarning("Created: {@eventargs}", e);

    private static void renameEvent(object sender, RenamedEventArgs e) => _logger.LogWarning("Renamed: {@eventargs}", e);

答案

本应该想出这个而不发布到堆栈......我的问题是两件事。我需要更改NotifyFilter以包含FileName更改并订阅已更改的事件，如下所示。

       CaptureServerSettings appSettings = provider.GetRequiredService<CaptureServerSettings>();
       using (FileSystemWatcher directoryWatcher = new FileSystemWatcher(appSettings.WatchDirectory, "*.*"))
       {
            directoryWatcher.BeginInit();
            directoryWatcher.IncludeSubdirectories = false;
            directoryWatcher.NotifyFilter = NotifyFilters.LastWrite | NotifyFilters.FileName;
            directoryWatcher.Created += createdEvent;
            directoryWatcher.Changed += changedEvent;
            directoryWatcher.EnableRaisingEvents = true;
            directoryWatcher.EndInit();
            provider.GetRequiredService<CancellationTokenSource>().Token.WaitHandle.WaitOne();
        }
