Filesystemwatcher不会触发事件

Question

我正在尝试使用FileSystemWatcher类监视目录中的新文件。

我的问题是该事件不会被触发。我的守望类是：

public class Filewatcher 
{ 
    private FileSystemWatcher watcher; 

    public Filewatcher(string path, string filefilter) 
    { 
     this.watcher = new FileSystemWatcher(); 
     this.watcher.Path = path; 
     this.watcher.NotifyFilter = NotifyFilters.FileName; //| NotifyFilters.LastWrite | NotifyFilters.LastAccess 
     this.watcher.Filter = filefilter; 
     this.watcher.Created += new FileSystemEventHandler(OnChanged); 
    } 

    public void start_watching() 
    { 
     //this.watcher.IncludeSubdirectories = true; 
     this.watcher.EnableRaisingEvents = true; 

     Console.WriteLine("Press Enter to quit\r\n"); 
     Console.ReadLine(); 
    } 

    private static void OnChanged(object source, FileSystemEventArgs e) 
    { 
     //FileInfo objFileInfo = new FileInfo(e.FullPath); 
     //if (!objFileInfo.Exists) return; 
     Console.WriteLine("got the change\r\n"); 
     global_functions.perform_action(Global_Vars.thereader.read(e.FullPath), Global_Vars.thepattern); 
    } 
}

你不打个电话给start_watching（）。添加一个电话，它可能会更好。
