解决C#中FileSystemWatcher类的Changed事件触发多次的问题。
fsw = new FileSystemWatcher(System.Environment.CurrentDirectory + "\\conf\","*.xml");
fsw.EnableRaisingEvents = true;
fsw.NotifyFilter = NotifyFilters.LastWrite;
fsw.Changed += new FileSystemEventHandler(fsw_Changed);
首先设置NotifyFilter为LastWrite,这个就屏蔽了因为杀毒软件等各种外部因素导致Changed事件被触发。
然后设置它的EnableRaisingEvents属性如下:
private void fsw_Changed(object sender,EventArgs e) { fsw.EnableRaisingEvents = false; LoadTreeViewData(); fsw.EnableRaisingEvents = true; }
