可以使用FileSystemWatcher类来监视文件或者文件夹的变化。
下面的代码可以用来监视重命名的行为。
FileSystemWatcher watcher = new FileSystemWatcher();
watcher.Path = @"C:\MyDirectory";
watcher.Renamed += new RenamedEventHandler(watcher_Renamed)
watcher.EnableRaisingEvents = true;
void watcher_Renamed(object sender, RenamedEventArgs e)
{
Console.WriteLine("File Renamed: Old Name: " + e.OldName +
" New Name: " + e.Name);
}
FileSystemWatcher类的其他事件如下：
watcher.Deleted += new FileSystemEventHandler(watcher_Deleted);
watcher.Changed += new FileSystemEventHandler(watcher_Changed);
watcher.Created += new FileSystemEventHandler(watcher_Created);
这些事件都传递一个 FileSystemEventArgs参数，这个参数包含 filename, full path, what action caused the event 等信息.
