使用FileSystemWatcher监视目录

问题是通知过滤器。该程序试图打开一个仍在复制的文件。我删除了除LastWrite之外的所有通知过滤器。

private void watch(){  FileSystemWatcher watcher = new FileSystemWatcher();  watcher.Path = path;  watcher.NotifyFilter = NotifyFilters.LastWrite;  watcher.Filter = "*.*";  watcher.Changed += new FileSystemEventHandler(OnChanged);  watcher.EnableRaisingEvents = true;}
