如何列出ftp服务器上的目录中的文件？

Question

问题如下：

我找到了一个能够列出ftp服务器根目录下的文件和目录的解决方案。但我也需要目录的内容。我需要修改这个方法吗？

internal void ListFilesOnServer() 
     { 
      try 
      { 
       FtpWebRequest ftpwrq = (FtpWebRequest)WebRequest.Create(server); 
       ftpwrq.Credentials = new NetworkCredential(user,passw); 
       ftpwrq.Method = WebRequestMethods.Ftp.ListDirectory; 
       ftpwrq.KeepAlive = false; 
       FtpWebResponse fresponse = (FtpWebResponse)ftpwrq.GetResponse(); 
       StreamReader sr = new StreamReader(fresponse.GetResponseStream()); 
       StreamWriter sw = new StreamWriter(new FileStream("test.txt", FileMode.Create)); 
       sw.WriteLine(sr.ReadToEnd()); 
       sw.Close(); 
       fresponse.Close(); 
       sr.Close(); 
       MessageBox.Show("Gotcha"); 
      } 
      catch (Exception e) 
      { 
       MessageBox.Show(e.Message); 
      } 
     }

则可以使用下面的代码做：

  reqFTP = (FtpWebRequest)FtpWebRequest.Create(new Uri(sUri)); 
      reqFTP.UseBinary = true; 
      reqFTP.Credentials = new NetworkCredential(sFtpUserID, sFtpPassword); 
      reqFTP.Method = WebRequestMethods.Ftp.ListDirectory; 
      reqFTP.Proxy = null; 
      reqFTP.KeepAlive = false; 
      reqFTP.UsePassive = false; 
      response = reqFTP.GetResponse(); 
      reader = new StreamReader(response.GetResponseStream()); 
      string line = reader.ReadLine(); 
      while (line != null) 
      { 
       result.Append(line); 
       result.Append("\n"); 
       line = reader.ReadLine(); 
      }
