ftp目錄列表超時。大量的子目錄

Question

當您需要獲取FTP服務器上所有目錄的列表時，有什麼辦法可以處理這種情況：目錄數量如此之大，以至於需要太長的時間才能得到它，而且操作因超時而失敗？

我不知道是否有一些圖書館讓你這麼做嗎？

嘗試是這樣的

 FtpWebRequest ftpRequest = (FtpWebRequest)WebRequest.Create(uri); 
     ftpRequest.Credentials = new NetworkCredential("anonymous","yourName@SomeDomain.com");//replace with your Creds 
     ftpRequest.Method = WebRequestMethods.Ftp.ListDirectory; 
     FtpWebResponse response = (FtpWebResponse)ftpRequest.GetResponse(); 
     StreamReader streamReader = new StreamReader(response.GetResponseStream()); 

     List<string> directories = new List<string>(); 

     string line = streamReader.ReadLine(); 
     while (!string.IsNullOrEmpty(line)) 
     { 
      directories.Add(line); 
      line = streamReader.ReadLine(); 
     } 

     streamReader.Close(); 

     // also add some code that will Dispose of the StreamReader object 
     // something like ((IDisposable)streanReader).Dispose(); 
     // Dispose of the List<string> as well 
      line = null;
