Filesystemwatcher用于文件打开通知

Question

请帮助我计算用户在filesystemwatcher的帮助下打开文件（.txt或.pdf）的次数。

甚至在将NotifyFilter-property设置为LastAccess并捕获Changed-event之后。像这样：

FileSystemWatcher lWatcher = new FileSystemWatcher(@"C:\Documents and Settings\User\Desktop", "myfile.txt");    
lWatcher.NotifyFilter = NotifyFilters.LastAccess;    
lWatcher.Changed += new FileSystemEventHandler(HandlerWatcherChanged);    

void HandlerWatcherChanged(object sender, FileSystemEventArgs e)
{
   // file has been accessed
} 

如有必要，我已启用上次访问时间更新。 我仍然无法得到它。

如果没有尝试以下代码：

FileSystemWatcher lWatcher = new FileSystemWatcher(@"C:\Documents and Settings\User\Desktop", "*.txt");    
lWatcher.NotifyFilter = NotifyFilters.LastAccess;    
lWatcher.EnableRaisingEvents = true;
lWatcher.Changed += new FileSystemEventHandler(HandlerWatcherChanged);    

void HandlerWatcherChanged(object sender, FileSystemEventArgs e)
{
   if (e.FullPath.Contains("mfile.txt")) 
         return; //do work here
}
