Example

The following example demonstrates how to download a file from an FTP server using FtpWebRequest and read the response using FtpWebResponse.


using System;
using System.IO;
using System.Net;
using System.Text;

public class FtpDownloadExample
{
    public static void DownloadFile(string ftpUrl, string localFileName)
    {
        FtpWebRequest request = (FtpWebRequest)WebRequest.Create(ftpUrl);
        request.Method = WebRequestMethods.Ftp.DownloadFile;
        request.Credentials = new NetworkCredential("anonymous", "user@example.com"); // Replace with your credentials

        try
        {
            using (FtpWebResponse response = (FtpWebResponse)request.GetResponse())
            {
                Console.WriteLine($"Download Complete, Status: {response.StatusDescription}");

                using (Stream responseStream = response.GetResponseStream())
                using (FileStream fileStream = File.Create(localFileName))
                {
                    responseStream.CopyTo(fileStream);
                }
            }
            Console.WriteLine($"File '{localFileName}' downloaded successfully.");
        }
        catch (WebException ex)
        {
            Console.Error.WriteLine($"FTP Error: {ex.Message}");
            if (ex.Response is FtpWebResponse errorResponse)
            {
                Console.Error.WriteLine($"FTP Status Code: {errorResponse.StatusCode}");
                Console.Error.WriteLine($"FTP Error Response: {errorResponse.FtpErrorResponse}");
            }
        }
        catch (Exception ex)
        {
            Console.Error.WriteLine($"An error occurred: {ex.Message}");
        }
    }

    public static void Main(string[] args)
    {
        // Example usage:
        // string ftpUrl = "ftp://ftp.example.com/path/to/your/file.txt";
        // string localFileName = "downloaded_file.txt";
        // DownloadFile(ftpUrl, localFileName);

        Console.WriteLine("Example usage commented out. Please uncomment and configure with your FTP details.");
    }
