FileSystemWatcher崩溃了 [英] FileSystemWatcher crashes
问题描述
我遇到的问题与此完全相同：
https：// connect .microsoft.com / VisualStudio / feedback / details / 780775 / filesystemwatcher-overlaped-listener-raising-an-exception-on-malformed-notifications
由于某种原因我不能在那里评论所以决定开始一个新的讨论话题。微软提到无法重现这个问题。
如果File Watcher Path非常长且300多个文件同时到达，我总能重现它。我手动从另一个文件夹复制它们。 Windows还警告我，某些文件名太长而且会被截断。
我在.NET服务中使用FileSystemWatcher，这个错误无法从中恢复。服务崩溃，我在Windows事件日志中看到以下错误：
框架版本：v4.0.30319
描述：流程已终止到期到未处理的例外。
异常信息：System.ArgumentException
at System.IO.Path.CheckInvalidPathChars（System.String，Boolean）
at System.IO.Path.GetFileName（System.String）
at System.IO.FileSystemWatcher.MatchPattern（System.String）
at System.IO.FileSystemWatcher.NotifyFileSystemEventArgs（Int32，System.String）
at System.IO.FileSystemWatcher.CompletionStatusChanged（UInt32，UInt32，System.Threading.NativeOverlapped *）
at System.Threading._IOCompletionCallback.PerformIOCompletionCallback（UInt32，UInt32，System.Threading.NativeOverlapped *）

Hi,
I am experiencing exactly the same issue as here:
https://connect.microsoft.com/VisualStudio/feedback/details/780775/filesystemwatcher-overlapped-listener-raising-an-exception-on-malformed-notifications
For some reason I can't comment there so decided to start a new discussion topic. Microsoft mentioned that can't reproduce the issue.
I can always reproduce it if File Watcher Path is very long and 300+ files arrive at the same time. I copy them from another folder manually. Windows also warned me that some file names are too long and will be truncated.
I use FileSystemWatcher in the .NET service and this error is impossible to recover from. Service crashes and I see the following error in Windows Event log:
Framework Version: v4.0.30319
Description: The process was terminated due to an unhandled exception.
Exception Info: System.ArgumentException
at System.IO.Path.CheckInvalidPathChars(System.String, Boolean)
at System.IO.Path.GetFileName(System.String)
at System.IO.FileSystemWatcher.MatchPattern(System.String)
at System.IO.FileSystemWatcher.NotifyFileSystemEventArgs(Int32, System.String)
at System.IO.FileSystemWatcher.CompletionStatusChanged(UInt32, UInt32, System.Threading.NativeOverlapped*)
at System.Threading._IOCompletionCallback.PerformIOCompletionCallback(UInt32, UInt32, System.Threading.NativeOverlapped*)
Please advise
Hi friend,
Thanks for your posting.
The same issue has been submitted a feedback, which you've posted the link of it. I just suggest you comment on that feedback, and the Microsoft engineers will evaluate it seriously.
