Good morning,

I'm developing a system that exchanges .txt files via FTP. I need to download all the files that are in a certain folder.

Today I can download one file at a time, in case I pass the connection credentials, folder name and filename, but that way it does not meet my needs.

The code below is working for a single download.

Can anyone tell me what I need to adjust in this code below? If this is possible to meet my need.

Thank you

    public static void StartDownloads(out string pstrMsg, out bool pbooRetorno, string pstrUrl, string pstrLocal, string pstrUsuario, string pstrSenha)
    {
        pstrMsg = string.Empty;
        pbooRetorno = false;

        try
        {
            // Get the object used to communicate with the server.
            FtpWebRequest request = (FtpWebRequest)WebRequest.Create(pstrUrl);
            request.Method = WebRequestMethods.Ftp.DownloadFile;

            // Credenciais utilizadas para conectar no servidor FTP
            request.Credentials = new NetworkCredential(pstrUsuario, pstrSenha);

            using (FtpWebResponse response = (FtpWebResponse)request.GetResponse())
            {
                Stream responseStream = response.GetResponseStream();

                using (StreamReader reader = new StreamReader(responseStream))
                {
                    // Cria o arquivo no local especificado
                    using (StreamWriter writer = new StreamWriter(pstrLocal))
                    {
                        string strLinhaArquivo = reader.ReadLine();

                        while (!String.IsNullOrEmpty(strLinhaArquivo))
                        {
                            // Gravar as informações no arquivo
                            writer.Write(strLinhaArquivo);

                            // Verifica se o arquivo extraido contém linha
                            if (!String.IsNullOrEmpty((strLinhaArquivo = reader.ReadLine())))
                            {
                                // Inseri uma nova linha no arquivo
                                writer.WriteLine();
                            }
                        }
                    }
                }
            }

            Uri uri = new Uri(pstrUrl);

            // Método deleta o arquivo assim que o download acaba
            DeleteFileOnServer(uri, pstrUsuario, pstrSenha); // request);

            pbooRetorno = true;
        }
        catch (Exception ex)
        {
            pstrMsg = string.Format("Erro:\nMétodo 'StartDownloads'\nDetalhes: {0}", ex.Message);

            pbooRetorno = false;
        }
    }

ftpClient.DownloadFile (pathRemota, pathLocal);

I went to do test download of several files, but gave error in this line saying "The format of the given path is not supported."

Could you help me?

Well, I already used the code below:

public void BaixarTodosArquivosDirFTP(string urlFTP, string usuario, string senha, string dirLocal)
{
    FtpWebRequest ftpRequest = (FtpWebRequest)WebRequest.Create(urlFTP);
    ftpRequest.Credentials = new NetworkCredential(usuario, senha);
    ftpRequest.Method = WebRequestMethods.Ftp.ListDirectory;
    FtpWebResponse response = (FtpWebResponse)ftpRequest.GetResponse();
    StreamReader streamReader = new StreamReader(response.GetResponseStream());           
    List<string> diretorios = new List<string>();            

    string line = streamReader.ReadLine();
    while (!string.IsNullOrEmpty(line))
    {
        diretorios.Add(line);
        line = streamReader.ReadLine();
    }
    streamReader.Close();


    using (WebClient ftpClient = new WebClient())
    {
        ftpClient.Credentials = new System.Net.NetworkCredential(usuario, senha);

        for (int i = 0; i <= diretorios.Count-1; i++)
        {
            if (diretorios[i].Contains("."))
            {

                string pathRemota = urlFTP + diretorios[i].ToString();
                string pathLocal = Path.Combine(urlFTP, diretorios[i].ToString());
                ftpClient.DownloadFile(pathRemota, pathLocal);
            }
        }
    }
}
