C# FileSystemWatcher 在监控文件夹和文件时的使用方法

class Program
  {
    static void Main(string[] args)
    {
      WatcherStrat(@"D:\spring\Program", "*.*");
      Console.ReadKey();
 
    }
 
    private static void WatcherStrat(string path, string filter)
    {
 
      FileSystemWatcher watcher = new FileSystemWatcher();
      watcher.Path = path;
      watcher.Filter = filter;
      watcher.Changed += new FileSystemEventHandler(OnProcess);
      watcher.Created += new FileSystemEventHandler(OnProcess);
      watcher.Deleted += new FileSystemEventHandler(OnProcess);
      watcher.Renamed += new RenamedEventHandler(OnRenamed);
      watcher.EnableRaisingEvents = true;
      watcher.NotifyFilter = NotifyFilters.Attributes | NotifyFilters.CreationTime | NotifyFilters.DirectoryName | NotifyFilters.FileName | NotifyFilters.LastAccess
                 | NotifyFilters.LastWrite | NotifyFilters.Security | NotifyFilters.Size;
      watcher.IncludeSubdirectories = true;
    }
 
    private static void OnProcess(object source, FileSystemEventArgs e)
    {
      if (e.ChangeType == WatcherChangeTypes.Created)
      {
        OnCreated(source, e);
      }
      else if (e.ChangeType == WatcherChangeTypes.Changed)
      {
        OnChanged(source, e);
      }
      else if (e.ChangeType == WatcherChangeTypes.Deleted)
      {
        OnDeleted(source, e);
      }
 
    }
    private static void OnCreated(object source, FileSystemEventArgs e)
    {
      Console.WriteLine("文件新建事件处理逻辑 {0} {1} {2}", e.ChangeType, e.FullPath, e.Name);
    }
    private static void OnChanged(object source, FileSystemEventArgs e)
    {
      Console.WriteLine("文件改变事件处理逻辑{0} {1} {2}", e.ChangeType, e.FullPath, e.Name);
    }

    {
