从网上FTP目录下的所有文件列表，列表视图C＃(List all files from online

我怎么能和其他人谁在读这份名单从在线目录中的所有文件到ListView？

这是代码的本地目录中列出我想知道是否有办法让这个是连接到FTP网站，并列出文件？

FolderBrowserDialog folderPicker = new FolderBrowserDialog();
if (folderPicker.ShowDialog() == DialogResult.OK)
{

    ListView1.Items.Clear();

    string[] files = Directory.GetFiles(folderPicker.SelectedPath);
    foreach (string file in files)
    {

        string fileName = Path.GetFileNameWithoutExtension(file);
        ListViewItem item = new ListViewItem(fileName);
        item.Tag = file;

        ListView1.Items.Add(item);

    }

}

我已经使用这个代码，但我似乎无法得到它的工作它不是来了一个错误，但它不是上市的web服务器上的文件要么？

private void ConnectBtn_Click(object sender, EventArgs e)
    {
        ListDirectory();
    }

    public string[] ListDirectory()
    {
        var list = new List<string>();

        var request = createRequest(TxtServer.Text, WebRequestMethods.Ftp.ListDirectory);

        using (var response = (FtpWebResponse)request.GetResponse())
        {
            using (var stream = response.GetResponseStream())
            {
                using (var reader = new StreamReader(stream, true))
                {
                    while (!reader.EndOfStream)
                    {
                        list.Add(reader.ReadLine());
                    }
                }
            }
        }

        return list.ToArray();
    }

    private FtpWebRequest createRequest(string uri, string method)
    {
        var r = (FtpWebRequest)WebRequest.Create(uri);

        r.Credentials = new NetworkCredential(TxtUsername.Text, TxtPassword.Text);
        r.Method = method;

        return r;
    }

Answer 1:

你可以使用这个包装库 。

相关的代码是：

    public string[] ListDirectory() {
        var list = new List<string>();

        var request = createRequest(WebRequestMethods.Ftp.ListDirectory);

        using (var response = (FtpWebResponse)request.GetResponse()) {
            using (var stream = response.GetResponseStream()) {
                using (var reader = new StreamReader(stream, true)) {
                    while (!reader.EndOfStream) {
                        list.Add(reader.ReadLine());
                    }
                }
            }
        }

        return list.ToArray();
    }

Answer 2:

这里是一个很好的帮手得到一个FTP目录下的所有文件和文件夹：

public static IEnumerable<string> GetFilesInFtpDirectory(string url, string username, string password)
{
    // Get the object used to communicate with the server.
    var request = (FtpWebRequest)WebRequest.Create(url);
    request.Method = WebRequestMethods.Ftp.ListDirectoryDetails;
    request.Credentials = new NetworkCredential(username,password);

    using (var response = (FtpWebResponse) request.GetResponse())
    {
        using (var responseStream = response.GetResponseStream())
        {
            var reader = new StreamReader(responseStream);
            while (!reader.EndOfStream)
            {
                var line = reader.ReadLine();
                if (string.IsNullOrWhiteSpace(line) == false)
                {
                    yield return line.Split(new[] { ' ', '\t' }).Last();    
                }
            }
        }
    }
}

我找到了答案，我做了一个小实验，现在它显示在列表视图中的文件，谢谢罗伯特·哈维♦

private void ConnectBtn_Click(object sender, EventArgs e)
    {
        ListDirectory();
    }

    public string[] ListDirectory()
    {
        var list = listView1;

        var request = createRequest(TxtServer.Text, WebRequestMethods.Ftp.ListDirectory);

        using (var response = (FtpWebResponse)request.GetResponse())
        {
            using (var stream = response.GetResponseStream())
            {
                using (var reader = new StreamReader(stream, true))
                {
                    while (!reader.EndOfStream)
                    {
                        list.Items.Add(reader.ReadLine());
                    }
                }
            }
        } List<string> l = new List<string>();
        return l.ToArray();
    }

    private FtpWebRequest createRequest(string uri, string method)
    {
        var r = (FtpWebRequest)WebRequest.Create(uri);

        r.Credentials = new NetworkCredential(TxtUsername.Text, TxtPassword.Text);
        r.Method = method;

        return r;
    }

Answer 4:

该代码可用于从FTP获得的文件列表

private void ftpFileRead()
{
  FtpWebRequest Request = (FtpWebRequest)WebRequest.Create("your ftpAddress");
  Request.Method = WebRequestMethods.Ftp.ListDirectory;     
  Request.Credentials = new NetworkCredential(your ftp username,your ftp password);
  FtpWebResponse Response = (FtpWebResponse)Request.GetResponse();
  Stream ResponseStream = Response.GetResponseStream();
  StreamReader Reader = new StreamReader(ResponseStream);

  ListBox1.Items.Add(Response.WelcomeMessage);
  while (!Reader.EndOfStream)//Read file name   
  {
    ListBox1.Items.Add(Reader.ReadLine().ToString());
  }
  Response.Close();
  ResponseStream.Close();
  Reader.Close();
}

Answer 5:

您可以使用此方法。

    public static string[] GetFiles(string path, NetworkCredential Credentials, SearchOption searchOption)
    {
        var request = (FtpWebRequest)WebRequest.Create(path);
        request.Method = WebRequestMethods.Ftp.ListDirectoryDetails;
        request.Credentials = Credentials;
        List<string> files = new List<string>();
        using (var response = (FtpWebResponse)request.GetResponse())
        {
            using (var responseStream = response.GetResponseStream())
            {
                var reader = new System.IO.StreamReader(responseStream);
                while (!reader.EndOfStream)
                {
                    var line = reader.ReadLine();
                    if (string.IsNullOrWhiteSpace(line) == false)
                    {
                        if (!line.Contains("<DIR>"))
                        {
                            string[] details = line.Split(new string[] { " " }, StringSplitOptions.RemoveEmptyEntries);
                            string file = line.Replace(details[0], "")
                                .Replace(details[1], "")
                                .Replace(details[2], "")
                                .Trim();
                            files.Add(file);
                        }
                        else
                        {
                            if (searchOption == SearchOption.AllDirectories)
                            {
                                string dirName = line.Split(
                                        new string[] { "<DIR>" },
                                        StringSplitOptions.RemoveEmptyEntries
                                        ).Last().Trim();
                                string dirFullName = String.Format("{0}/{1}", path.Trim('/'), dirName);
                                files.AddRange(GetFiles(dirFullName, Credentials, searchOption));
                            }
                        }
                    }
                }
            }
        }
        return files.ToArray();
    }
