Hi,

I have two variable that contains the path of the file in the ftp:

the first variable called  file1 contains that value : ds/product/Jan/09122016_product.csv
the second variable called file2 contains that value : ds/subproduct/Jan/09122016_subproduct.csv
the third variable called  file3 contains that value : ds/category/Jan/09122016_category.csv

each file is in different folder but the same server 

what i want is to check if the 3 files exists in the ftp 

Thanks

MSDN has some samples

For example,  https://msdn.microsoft.com/en-us/library/ms229716%28v=vs.110%29.aspx

Hi YassirCool,

Thank you for posting here.

For your question, please try the following code.

private bool CheckIfFileExistsOnServer(string fileName)    
{    
    var request = (FtpWebRequest)WebRequest.Create("ftp://www.server.com/" + fileName);    
    request.Credentials = new NetworkCredential("username", "password");    
    request.Method = WebRequestMethods.Ftp.GetFileSize;    
    
    try    
    {    
        FtpWebResponse response = (FtpWebResponse)request.GetResponse();    
        return true;    
    }    
    catch (WebException ex)    
    {    
        FtpWebResponse response = (FtpWebResponse)ex.Response;    
        if (response.StatusCode == FtpStatusCode.ActionNotTakenFileUnavailable)    
            return false;    
    }    
    return false;    
}  

I hope this would be helpful to you.

Best Regards,

Wendy

Hi YassirCool,

I configure a FTP and make a simple code to test.

Please try the code I provide from MSDN article.

I have a .txt file like the following. I show the file content in ftp.

I use the code with UserName and PassWord.

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Net;
using System.Text;
using System.Text.RegularExpressions;
using System.Threading.Tasks;

namespace FTP_Check_Files
{
    class Program
    {
        static void Main(string[] args)
        {
           CheckIfFileExistsOnServer("N/N1/N1.txt");//Here is the path in ftp, you could refer to the screenshot of the .txt file.
        }
        private static bool CheckIfFileExistsOnServer(string fileName)
        {
            var request = (FtpWebRequest)WebRequest.Create("ftp://localhost/" + fileName);
            request.Credentials = new NetworkCredential("xxxx(UserName)", "xxxx(PassWord)");
            request.Method = WebRequestMethods.Ftp.GetFileSize;

            try
            {
                FtpWebResponse response = (FtpWebResponse)request.GetResponse();
                Console.WriteLine("The file exists.");                                return true;
            }
            catch (WebException ex)
            {
                FtpWebResponse response = (FtpWebResponse)ex.Response;
                if (response.StatusCode == FtpStatusCode.ActionNotTakenFileUnavailable)
                    return false;
            }
            return false;
        }
    }
}

Here is the output.

I hope this would be helpful. Please have a try.

Best Regards,

Wendy
