FileSystemWatcher的观看UNC路径 [英] FileSystemWatcher to watch UNC path

问题描述

有关于这个主题的问题不缺，但我仍然有问题。这里是我的情况。我有我需要注意的是在配置文件中指定的路径的服务。当我用一个本地驱动器，它的伟大工程。

然而，当我将其更改为类似\\\\服务器2 \\辅助\\ TEMP \\ watch_folder服务没有启动。在日志中的错误是目录名\\\\服务器2 \\辅助\\ TEMP \\ watch_folder是无效的。如果我复制直接进入Windows资源管理器的文件夹打开罚款。如果我把我的code并将其粘贴到一个旧的WinForms应用程序，它工作正常。我已经尝试了所有的的登录为帐户。我将它设置为使用管理员帐户，但仍然没有骰子。

下面是我的code：

  _watcher =新FileSystemWatcher的（）;
_watcher.Path = ConfigurationManager.AppSettings [WatchFolder];
_watcher.NotifyFilter = NotifyFilters.LastWrite | NotifyFilters.FileName;
_watcher.Filter =* .TXT
_watcher.Created + =新FileSystemEventHandler（OnCreated）;
_watcher.Error + =新ErrorEventHandler（的OnError）;
_watcher.EnableRaisingEvents = TRUE;
 

任何想法？我不知所措，在这一点上我想我被它太长时间盯着。我衷心AP preciate任何帮助。

谢谢，
尼克

的 修改的
这里是个例外：

 服务不能启动。 System.ArgumentException：目录名\\\\服务器2 \\辅助\\ TEMP \\ watch_folder是无效的。
在System.IO.FileSystemWatcher.set_Path（字符串值）
在FileWatcher.FileWatcher.Watch（）
在FileWatcher.FileWatcher.OnStart（字串[] args）
在System.ServiceProcess.ServiceBase.ServiceQueuedMainCallback（对象状态）
 

解决方案

我只是尝试这样的：

  VAR _watcher =新FileSystemWatcher的（）;
_watcher.Path = @\\\\ 10.31.2.221 \\共享\\;
_watcher.NotifyFilter = NotifyFilters.LastWrite | NotifyFilters.FileName;
_watcher.Filter =* .TXT
_watcher.Created + =新FileSystemEventHandler（（X，Y）=＆GT; Console.WriteLine（创建））;
_watcher.Error + =新ErrorEventHandler（（X，Y）=＆GT; Console.WriteLine（错误））;
_watcher.EnableRaisingEvents = TRUE;
Console.ReadKey（）;
 

这是没有问题的作品，但是我复制你的异常就在：

• 运行用户没有权限来读取远程文件夹。


• 远程文件夹不存在。

您的问题肯定与权限有关，我认为正在运行的用户没有所需的权限。

另一件事，你可以尝试在远程文件夹映射到一个地方。

在cmd

执行此：

  NET USE Z：\\\\服务器2 \\辅助\\ TEMP \\ watch_folder /用户：域\\用户名密码
 

然后在你的code：

  _watcher.Path = @Z：\\;
 

There are no shortage of questions on this topic, but I'm still having trouble. Here is my situation. I've got a service that I need to watch a path that is specified in the config file. It works great when I used a local drive.

However, when I change it to something like \\server2\secondary\temp\watch_folder the service does not start. The error in the log is "The directory name \\server2\secondary\temp\watch_folder is invalid." If I copy that directly into Windows Explorer the folder opens fine. If I take my code and paste it into an old Winforms app it works fine. I've tried all of the "Log On As" accounts. I set it to use the Administrator account, but still no dice.

Here is my code:

_watcher = new FileSystemWatcher();
_watcher.Path = ConfigurationManager.AppSettings["WatchFolder"];
_watcher.NotifyFilter = NotifyFilters.LastWrite | NotifyFilters.FileName;
_watcher.Filter = "*.txt";
_watcher.Created += new FileSystemEventHandler(OnCreated);
_watcher.Error += new ErrorEventHandler(OnError);
_watcher.EnableRaisingEvents = true;

Any ideas? I'm at a loss and at this point I think I've been staring at it too long. I sincerely appreciate any help.

Thanks, Nick

EDIT Here is the exception:

Service cannot be started. System.ArgumentException: The directory name \\server2\Secondary\temp\watch_folder is invalid.
at System.IO.FileSystemWatcher.set_Path(String value)
at FileWatcher.FileWatcher.Watch()
at FileWatcher.FileWatcher.OnStart(String[] args)
at System.ServiceProcess.ServiceBase.ServiceQueuedMainCallback(Object state)

解决方案

I just tried this:

var _watcher = new FileSystemWatcher();
_watcher.Path = @"\\10.31.2.221\shared\";
_watcher.NotifyFilter = NotifyFilters.LastWrite | NotifyFilters.FileName;
_watcher.Filter = "*.txt";
_watcher.Created += new FileSystemEventHandler((x, y) =>Console.WriteLine("Created"));
_watcher.Error += new ErrorEventHandler( (x, y) =>Console.WriteLine("Error"));
_watcher.EnableRaisingEvents = true;
Console.ReadKey();

That works without problems, however i replicated your exception just when:

• The running user doesn't have permissions to read the remote folder.
• The remote folder doesn't exist.

Your problem surely is related with permissions, I think that the running user doesn't have the permissions needed.

Another thing that you can try is map the remote folder to one local.

Execute this in the cmd:

NET USE Z: \\server2\Secondary\temp\watch_folder /user:Domain\UserName Password

Then in your code:

_watcher.Path = @"Z:\";
