如何创建在文件系统中修改、创建或删除任何文件后触发的事件

Question

我想创建一个 windows 服务，它检测是否对文件系统中的任何文件进行了任何更改（创建、删除或修改）。当它检测到更改时，我将检查是否对相关文件进行了更改。如果是这样，那么我会将文件同步到服务器。我知道我将如何同步文件，我只想知道如何创建一个事件，只要对文件系统进行任何更改就会触发该事件。该事件还应提供有关修改的文件路径、对文件执行的操作的信息。

您只需初始化FileSystemWatcher并订阅相关事件即可。

FileSystemWatcher watcher = new FileSystemWatcher(@"DirectoryPath");
watcher.Filter = "*.*";//Watch all the files
watcher.EnableRaisingEvents = true;

//Specifies changes to watch for in a file or folder.
watcher.NotifyFilter = NotifyFilters.LastWrite | NotifyFilters.Size;

//订阅以下活动

watcher.Changed += new FileSystemEventHandler(watcher_Changed);
watcher.Created += new FileSystemEventHandler(watcher_Created);
watcher.Deleted += new FileSystemEventHandler(watcher_Deleted);

//Raise when new file is created
private void watcher_Created(object sender, FileSystemEventArgs e)
{
  //Sync with server
}

//Raise when file is modified
private void watcher_Changed(object sender, FileSystemEventArgs e)
{
  //Sync with server
}    

//Raise when a file is deleted
private void watcher_Deleted(object sender, FileSystemEventArgs e)
{
  //Sync with server
}
