Filesystemwatcher在一個文件夾並獲取文件名

Question

我使用FileSystemWatcher來監視幾個文件夾。 當它觸發更改事件時，我想獲取更改文件的文件名。 由於觀察者正在監視文件夾，當我嘗試使用e.Name或e.FullPath時，我得到文件夾路徑。

有沒有辦法獲得文件名？

代碼： 它是一個觀察者陣列。

watchers[_Idx] = new FileSystemWatcher(); 
watchers[_Idx].Path = row.Cells[0].Value.ToString(); 
watchers[_Idx].IncludeSubdirectories = true; 
watchers[_Idx].NotifyFilter = NotifyFilters.LastWrite | 
          NotifyFilters.DirectoryName | NotifyFilters.FileName | 
          NotifyFilters.Size; 
watchers[_Idx].Changed += new FileSystemEventHandler(SyncThread); 
watchers[_Idx].Created += new FileSystemEventHandler(SyncThread); 
watchers[_Idx].Renamed +=new RenamedEventHandler(SyncThread); 
watchers[_Idx].EnableRaisingEvents = true;

您可以從事件中提取的文件名：

// Define the event handlers. 
private static void OnChanged(object source, FileSystemEventArgs e) 
{ 
    // Specify what is done when a file is changed, created, or deleted. 
    Console.WriteLine("File: " + e.FullPath + " " + e.ChangeType); 
} 

private static void OnRenamed(object source, RenamedEventArgs e) 
{ 
    // Specify what is done when a file is renamed. 
    Console.WriteLine("File: {0} renamed to {1}", e.OldFullPath, e.FullPath); 
}
