Answer 1

你是怎么changed的？修改后没有关闭？
2 是你的"d:\\yangd\\down低下有没有重名的zip文件

Answer 2

解决拉，娃哈哈，
我加了　这三行就转了
        watcher.Changed += new FileSystemEventHandler(OnRenamed);
        watcher.Created += new FileSystemEventHandler(OnChanged);
        watcher.Deleted += new FileSystemEventHandler(OnRenamed);
        watcher.Renamed += new RenamedEventHandler(OnRenamed);
        private static void OnRenamed(object source, FileSystemEventArgs e)
        {
            // Specify what is done when a file is changed, created, or deleted.
            //LibWrap.MsgBox(0, e.FullPath, e.FullPath, 0);            //extract(e.FullPath);        }
