我如何为ftpDirectory使用foreach循环 [英] How do i use foreach loop for ftpDirectory

问题描述

  foreach （ string  f  in  Directory.GetFiles（（  ftp：// me @ localhost / + newFolder）））

错误：给定路径不支持 。

newFolder由子目录和文件组成。

解决方案

你不能只是获取ftp列表来自Directory类：您必须首先设置FTP连接：

 FTPGetListing（ @ < span class =code-string>用户名， 密码，  ftp.Images.MyDomain.com）; 
 ... 
  private   void  FTPGetListing（ string  user， string  password， string  ftpURL）
 {
  string  strConnect =  string  .Format（  ftp：// {0}，ftpURL）; 
 FtpWebRequest ftp =（FtpWebRequest）FtpWebRequest.Create（strConnect）; 
 ftp.Credentials =  new  NetworkCredential（用户，密码）; 
 ftp.KeepAlive =  false ; 
 ftp.Method = WebRequestMethods.Ftp.DownloadFile; 
 ftp.UseBinary =  true ; 
 ftp.Proxy =  null ; 
 ftp.UsePassive =  false ; 
 List< string>文件夹，文件; 
 FTPGetFolder（ftp， @  \， out 个文件夹， out 个文件）; 
  //   ...  
} 
  private   void  FTPGetFolder（FtpWebRequest请求， string  baseFolder， out 列表< string>文件夹， out 列表< string>文件）
 {
请求.Method = WebRequestMethods.Ftp.ListDirectoryDe​​tails; 
 FtpWebResponse response =（FtpWebResponse）request.GetResponse（）; 
流responseStream = response.GetResponseStream（）; 
 StreamReader reader =  new  StreamReader（responseStream）; 
  string  listing = reader.ReadToEnd（）; 
 folders =  new  List< string>（）; 
 files =  new  List< string>（）; 
  string  [] lines = listing.Split（'  \ n'，'  \ r'）; 
  foreach （ string  line  in 行）
 {
 ... 
} 
 reader.Close（）; 
 response.Close（）; 
} 

额外标签< ; /串GT;< /串>中删除。

正如消息所示，您无法列出FTP路径中的文件。

这可能会有所帮助：如何：使用FTP列出目录内容 [ ^ ]

< blockquote>我认为你不能使用Directory类进行FTP，而是使用FtpWebRequest。



FtpWebRequest类 [ ^ ]

foreach (string f in Directory.GetFiles(("ftp://me@localhost/" + newFolder)))

Error: Given Path is not supported.

newFolder consists of sub directories and files.

解决方案

You can''t just get ftp listings from the Directory class: you have to set up an FTP connection first:

            FTPGetListing(@"Username", "Password", "ftp.Images.MyDomain.com");
...
        private void FTPGetListing(string user, string password, string ftpURL)
            {
            string strConnect = string.Format("ftp://{0}", ftpURL);
            FtpWebRequest ftp = (FtpWebRequest)FtpWebRequest.Create(strConnect);
            ftp.Credentials = new NetworkCredential(user, password);
            ftp.KeepAlive = false;
            ftp.Method = WebRequestMethods.Ftp.DownloadFile;
            ftp.UseBinary = true;
            ftp.Proxy = null;
            ftp.UsePassive = false;
            List<string> folders, files;
            FTPGetFolder(ftp, @"\", out folders, out files);
            // ...
            }
        private void FTPGetFolder(FtpWebRequest request, string baseFolder, out List<string> folders, out List<string> files)
            {
            request.Method = WebRequestMethods.Ftp.ListDirectoryDetails;
            FtpWebResponse response = (FtpWebResponse)request.GetResponse();
            Stream responseStream = response.GetResponseStream();
            StreamReader reader = new StreamReader(responseStream);
            string listing = reader.ReadToEnd();
            folders = new List<string>();
            files = new List<string>();
            string[] lines = listing.Split('\n', '\r');
            foreach (string line in lines)
                {
                ...
                }
            reader.Close();
            response.Close();
            }

Extra tags "</string></string>" removed.

As the as message says, you cannot list files from a FTP path.

I think you can''t use Directory class for FTP, use FtpWebRequest instead.
