本文介绍了子目录中的文件FileSystemWatcher的的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我想,如果一个文件被创建,复制或移动到一个目录我看得到通知。
我只想得到,虽然有关文件通知,而不是目录

I'm trying to be notified if a file is created, copied, or moved into a directory i'm watching.I only want to be notified about the files though, not the directories.

下面是一些代码,我公司目前拥有的:

Here's some of the code I currently have:

_watcher.NotifyFilter = NotifyFilters.FileName;
_watcher.Created += new FileSystemEventHandler(file_created);
_watcher.Changed += new FileSystemEventHandler(file_created);
_watcher.Renamed += new RenamedEventHandler(file_created);
_watcher.IncludeSubdirectories = true;
_watcher.EnableRaisingEvents = true;



但问题是,如果我移动包含在其中的文件的目录,我得到了,没有事件文件。

Problem is, if I move a directory that contains a file in it, I get no event for that file.

我怎样才能得到它来通知我要添加的所有文件(不论如何)到监视目录或它的子目录?

How can I get it to notify me for all files added (regardless of how) to the watched directory or it's sub directories?

柜面我没有解释不够好......我的 WatchedDirectory directory1目录的。的 directory1目录的包含的 hello.txt的的。如果我移动的 directory1目录的成的 WatchedDirectory 的,我想收到的的 hello.txt的

Incase I didn't explain good enough... I have WatchedDirectory, and Directory1. Directory1 contains Hello.txt. If I move Directory1 into WatchedDirectory, I want to be notified for Hello.txt.

编辑:我要指出我的操作系统是Windows 8,而我做得到复制/粘贴事件的通知,但不动的事件(拖放到文件夹中)

I should note my OS is Windows 8. And I do get notification for copy/paste events, but not move events (drag and drop into the folder).

推荐答案

也许这种解决方法可以派上用场(但由于涉及递归我会小心的性能):

Maybe this workaround could come in handy (but I'd be careful about performance as it involves recursion):

private static void file_created(object sender, FileSystemEventArgs e)
{
    if (e.ChangeType == WatcherChangeTypes.Created)
    {
        if (Directory.Exists(e.FullPath))
        {
            foreach (string file in Directory.GetFiles(e.FullPath))
            {
                var eventArgs = new FileSystemEventArgs(
                    WatcherChangeTypes.Created,
                    Path.GetDirectoryName(file),
                    Path.GetFileName(file));
                file_created(sender, eventArgs);
            }
        }
        else
        {
            Console.WriteLine("{0} created.",e.FullPath);
        }
    }
}
