vs2005bug--fileSystemWatcher为何执行两次？

Question

this.fileSystemWatcher.Path= "c:\\";
this.fileSystemWatcher.Filter= "bound.txt";
this.fileSystemWatcher.EnableRaisingEvents = true;
this.fileSystemWatcher.EnableRaisingEvents = true;
            this.fileSystemWatcher.NotifyFilter = System.IO.NotifyFilters.LastWrite;
            this.fileSystemWatcher.SynchronizingObject = this;
            this.fileSystemWatcher.Changed += new System.IO.FileSystemEventHandler(this.fileSystemWatcher_Changed);
然后用ctrl+c拷贝文件，用ctrl+v粘贴替换，发现changed在同一秒产生两次
2006－10－17 11：30：20 c:\bound.txt changed
2006－10－17 11：30：20 c:\bound.txt changed
两次记录一摸一样，晕，是vs2005的bug？

Answer 1

private void fileSystemWatcher_Changed(object sender, FileSystemEventArgs e)
        {
            if (e.ChangeType == WatcherChangeTypes.Changed)
            {
                fileSystemWatcher.EnableRaisingEvents = false;
                  ....
            }
         }
我得changed是这样写的

Answer 2

我用thread.sleep(1000)暂停一会儿就解决了，微软真他妈的笨蛋，我是天才:)
