C#文件監控對象FileSystemWatcher實例，通過監控文件創建、修改、刪除、重命名對服務器數據進行實時備份

先上圖，簡單的windorm界面；此為最初的版本，后續會增加監聽多個源目錄的功能、log功能、進度條展示功能等。

1、初始化監聽

 /// <summary>
        /// 初始化監聽
        /// </summary>
        /// <param name="StrWarcherPath">需要監聽的目錄</param>
        /// <param name="FilterType">需要監聽的文件類型(篩選器字符串)</param>
        /// <param name="IsEnableRaising">是否啟用監聽</param>
        /// <param name="IsInclude">是否監聽子目錄</param>
        private static void WatcherStrat(string StrWarcherPath, string FilterType, bool IsEnableRaising, bool IsInclude)
        {
            //初始化監聽
            watcher.BeginInit();
            //設置監聽文件類型
            watcher.Filter = FilterType;
            //設置是否監聽子目錄
            watcher.IncludeSubdirectories = IsInclude;
            //設置是否啟用監聽?
            watcher.EnableRaisingEvents = IsEnableRaising;
            //設置需要監聽的更改類型(如:文件或者文件夾的屬性,文件或者文件夾的創建時間;NotifyFilters枚舉的內容)
            watcher.NotifyFilter = NotifyFilters.Attributes | NotifyFilters.CreationTime | NotifyFilters.DirectoryName | NotifyFilters.FileName | NotifyFilters.LastAccess | NotifyFilters.LastWrite | NotifyFilters.Security | NotifyFilters.Size;
            //設置監聽的路徑
            watcher.Path = StrWarcherPath;
            //注冊創建文件或目錄時的監聽事件
            //watcher.Created += new FileSystemEventHandler(watch_created);
            //注冊當指定目錄的文件或者目錄發生改變的時候的監聽事件
            watcher.Changed += new FileSystemEventHandler(watch_changed);
            //注冊當刪除目錄的文件或者目錄的時候的監聽事件
            watcher.Deleted += new FileSystemEventHandler(watch_deleted);
            //當指定目錄的文件或者目錄發生重命名的時候的監聽事件
            watcher.Renamed += new RenamedEventHandler(watch_renamed);
            //結束初始化
            watcher.EndInit();
        }

        

2、啟動或者停止監聽

/// <summary>
        /// 啟動或者停止監聽
        /// </summary>
        /// <param name="IsEnableRaising">True:啟用監聽,False:關閉監聽</param>
        private void WatchStartOrSopt(bool IsEnableRaising)
        {
            watcher.EnableRaisingEvents = IsEnableRaising;
        }

3、監聽以后的事件

 /// <summary>
        /// 創建文件或者目錄時的監聽事件
        /// </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();                                                                   //啟動線程
        }

 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)
        {
            //事件內容
            MessageBox.Show("監聽到刪除事件" + 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();
        }

 

此處采用多線程的方式去復制文件，下面是復制文件的類

class FugaiFile
        {
            public object sender;
            public FileSystemEventArgs e;

            public void C()
            {
                //MessageBox.Show("監聽到修改事件" + e.FullPath);
                //MessageBox.Show(e.Name + "監聽到創建事件" + 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);
            }
        }
