List all files from FTP online directory to C # list

Question

Like me and everyone who reads this list, all the files from the online directory to the list?

This is the code for the local directory to be specified. I would like to know if there is a way to do this so that it connects to the FTP site and displays the files?

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); } } 

I used this code, but I can not get it to work so that it does not appear with an error, but does it not display files on the web server?

 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

You can use this wrapper library .

Relevant Code:

  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(); }

Here is a good helper for getting all the files and folders of an FTP directory:

 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(); } } } } }

I found an answer that I experimented a bit, and now it displays the files in a list, thanks Robert Harvey ♦

 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; }

This code can be used to list ftp files.

 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(); }

You can use this method.

  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(); }
