FileSystemWatcher的事件触发的问题（S） [英] FileSystemWatcher event trigger problem(s)

问题描述

这似乎是，FileSystemWatcher的触发事件不止一次。这里是我的设置;

It seems like , FileSystemWatcher triggers events more than once. Here is my settings ;

 watcher = new FileSystemWatcher();
 watcher.Path = @"D:\testSpace";
 watcher.InternalBufferSize = 1024*64;
 watcher.Deleted += Triggered;
 watcher.Changed += Triggered;
 watcher.Created += Triggered;
 watcher.Error += ErrorOccured;
 watcher.NotifyFilter = NotifyFilters.LastWrite;
 watcher.IncludeSubdirectories = true;

 watcher.EnableRaisingEvents = true; 

• 如果您更改文档，文件更改事件触发两次。

  • If you change a document , Document changed event triggered twice.

    新创建的事件不被触发，除非该文件夹下创建一个新的文件。文件夹

    New folder created event does not get triggered unless a new file created under the folder.

    删除事件不会触发（使用移删除，以及尝试）

    Deleted event not fired ( tried using shift delete as well)

    做你们知道的任何工作，围绕这些问题？

    do you guys know any work around for these issues ?

    推荐答案

    的 FileSystemWatcher的：

    通用文件系统操作可能   提高多个事件。对于   例如，当一个文件从一个移动   目录到另一个，几   并调用onChanged一些OnCreated和   OnDeleted事件可能得到提升。   移动一个文件是一个复杂的操作   它由多个简单的   操作，因此，提高多   事件。同样地，某些应用   （例如防病毒软件）   可能会导致额外的文件系统   是由检测到的事件   FileSystemWatcher的。

    Common file system operations might raise more than one event. For example, when a file is moved from one directory to another, several OnChanged and some OnCreated and OnDeleted events might be raised. Moving a file is a complex operation that consists of multiple simple operations, therefore raising multiple events. Likewise, some applications (for example, antivirus software) might cause additional file system events that are detected by FileSystemWatcher.
