先上图,简单的windorm界面;此为最初的版本,后续会增加监听多个源目录的功能、log功能、进度条展示功能等。
1、初始化监听
/// <summary> /// 初始化监听 /// </summary> /// <param name="StrWarcherPath">需要监听的目录</param> /// <param name="FilterType">需要监听的文件类型(筛选器字符串)</param> /// <param name="IsEnableRaising">是否启用监听</param> /// <param name="IsInclude">是否监听子目录</param> private static void WatcherStrat(string StrWarcherPath, string FilterType, bool IsEnableRaising, bool IsInclude) { //初始化监听 watcher.BeginInit(); //设置监听文件类型 watcher.Filter = FilterType; //设置是否监听子目录 watcher.IncludeSubdirectories = IsInclude; //设置是否启用监听? watcher.EnableRaisingEvents = IsEnableRaising; //设置需要监听的更改类型(如:文件或者文件夹的属性,文件或者文件夹的创建时间;NotifyFilters枚举的内容) watcher.NotifyFilter = NotifyFilters.Attributes | NotifyFilters.CreationTime | NotifyFilters.DirectoryName | NotifyFilters.FileName | NotifyFilters.LastAccess | NotifyFilters.LastWrite | NotifyFilters.Security | NotifyFilters.Size; //设置监听的路径 watcher.Path = StrWarcherPath; //注册创建文件或目录时的监听事件 //watcher.Created += new FileSystemEventHandler(watch_created); //注册当指定目录的文件或者目录发生改变的时候的监听事件 watcher.Changed += new FileSystemEventHandler(watch_changed); //注册当删除目录的文件或者目录的时候的监听事件 watcher.Deleted += new FileSystemEventHandler(watch_deleted); //当指定目录的文件或者目录发生重命名的时候的监听事件 watcher.Renamed += new RenamedEventHandler(watch_renamed); //结束初始化 watcher.EndInit(); }
2、启动或者停止监听
/// <summary> /// 启动或者停止监听 /// </summary> /// <param name="IsEnableRaising">True:启用监听,False:关闭监听</param> private void WatchStartOrSopt(bool IsEnableRaising) { watcher.EnableRaisingEvents = IsEnableRaising; }
3、监听以后的事件
/// <summary> /// 创建文件或者目录时的监听事件 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> private static void watch_created(object sender, FileSystemEventArgs e) { FugaiFile m = new FugaiFile(); m.sender = sender; m.e = e; Thread t = new Thread(new ThreadStart(m.C)); t.Start(); //启动线程 } private static void watch_changed(object sender, FileSystemEventArgs e) { FugaiFile m = new FugaiFile(); m.sender = sender; m.e = e; Thread t = new Thread(new ThreadStart(m.C)); t.Start(); } private static void watch_deleted(object sender, FileSystemEventArgs e) { //事件内容 MessageBox.Show("监听到删除事件" + e.FullPath); } private static void watch_renamed(object sender, RenamedEventArgs e) { FugaiFile m = new FugaiFile(); m.sender = sender; m.e = e; Thread t = new Thread(new ThreadStart(m.C)); t.Start(); }
此处采用多线程的方式去复制文件,下面是复制文件的类
class FugaiFile { public object sender; public FileSystemEventArgs e; public void C() { //MessageBox.Show("监听到修改事件" + e.FullPath); //MessageBox.Show(e.Name + "监听到创建事件" + e.FullPath); String fullname = e.FullPath; string newpath = fullname.Replace(srcPath, TargetPath).Replace("\" + e.Name, ""); DirectoryInfo newFolder = new DirectoryInfo(newpath); if (!newFolder.Exists) { newFolder.Create(); } FileInfo aa = new FileInfo(e.FullPath); aa.CopyTo(newpath + "\" + e.Name, true); } }
