C# 時時監聽目錄文件改動

C# 時時監聽目錄文件改動:

public static class DirectoryListen
{
////public static string CountListXmlPath = CountCore.CountListXmlPath;
////public static string DirectoryListenPath = CountCore.ListenerAssemblyDirectory;
[PermissionSetAttribute(SecurityAction.Demand, Name = "FullTrust")]
public static void Run()
{
FileSystemWatcher watcher = new FileSystemWatcher();
watcher.Path = AppDomain.CurrentDomain.BaseDirectory;
/* 設置為監視 LastWrite 和 LastAccess 時間方面的更改，以及目錄中文本文件的創建、刪除或重命名。 */
watcher.NotifyFilter = NotifyFilters.LastAccess | NotifyFilters.LastWrite
| NotifyFilters.FileName | NotifyFilters.DirectoryName;
// 只監控.dll文件
watcher.Filter = "*.dll";

// 添加事件處理器。
watcher.Changed += new FileSystemEventHandler(OnChanged);
watcher.Created += new FileSystemEventHandler(OnChanged);
watcher.Deleted += new FileSystemEventHandler(OnChanged);
watcher.Renamed += new RenamedEventHandler(OnChanged);

// 開始監控。
watcher.EnableRaisingEvents = true;
}
public static void OnChanged(object source, FileSystemEventArgs e)
{
Console.WriteLine("有文件被改動過");
}
}
