直接说方法：

 1         public string[] GetFileList()
 2         {
 3             string[] downloadFiles;
 4             StringBuilder result = new StringBuilder();
 5             FtpWebRequest reqFTP;
 6             try
 7             {
 8                 reqFTP = (FtpWebRequest)FtpWebRequest.Create(new Uri(@ftp://192.168.13.1 + "/"));
 9                 reqFTP.UseBinary = true;
10                 reqFTP.Credentials = new NetworkCredential("Administrator","123456");
11                 reqFTP.Method = WebRequestMethods.Ftp.ListDirectory;
12                 WebResponse response = reqFTP.GetResponse();
13                 StreamReader reader = new StreamReader(response.GetResponseStream(),Encoding.Default);
14 
15                 string line = reader.ReadLine();
16                 while (line != null)
17                 {
18                     result.Append(line);
19                     result.Append("\n");
20                     line = reader.ReadLine();
21                 }
22                 // to remove the trailing '\n'
23                 result.Remove(result.ToString().LastIndexOf('\n'), 1);
24 
25 
26                 reader.Close();
27                 response.Close();
28                 return result.ToString().Split('\n');
29             }
30             catch (Exception ex)
31             {
32                 System.Windows.Forms.MessageBox.Show(ex.Message);
33                 downloadFiles = null;
34                 return downloadFiles;
35             }
36         }
