Downloading File from FTP

Karthi Keyan

Hi,

I am Making a tool that download the files from ftp. i did that. but i have some doubts. for downloading the files i want to give the path with End file name. like follow.

ftp://xxx.xxx.xxx.21//Direcotry/Sub_Directory1/Sub_Directory2/Sub_Directory3/Filename.zip

But i want to download the file by giving the path like follow,

ftp://xxx.xxx.xxx.21//Direcotry/Sub_Directory1/Sub_Directory2/Sub_Directory3

because if there were more number of files in Sub_Directory3 , then i want to give all the file names for download. to avoid that i asking this. i think it's possible. but i don't know how to do that. can any one guide me tho that.

Thanks in Advance.

@Amit.
I found the solution. i didn't give the download file namein the local path string.

While Error :

ftpClient.DownloadFile(path, localpath);

Now :

ftpClient.DownloadFile(path, dirpath.ToString()+"\\" + directories[i].ToString());

my code will download all the files, sub directories and the files inside the sub-directories.
and also that maintain the Directory structure which is same like in FTP. use that amit.

Thank You.

This my new code. just modified the code which i had sent you in the morning, in that code file downloded from ftp, but in this code file was not downloading. i got a error in ftpClient.DownloadFile(path, localpath); line. "could not find the part of the path" this is the error. it say's that the local path i snot exist. but i the localpath is correct. that's already exists. also that worked in the morning. but not now. i can't find the solution. what is the problem.

txtftpaddress.Text = > path of the ftp file.

try
{

FtpWebRequest ftpRequest = (FtpWebRequest)WebRequest.Create("ftp://xxx.xxx.xxx.xx/" + txtftpaddress.Text);
ftpRequest.Credentials = new NetworkCredential(txtusername.Text, txtpassword.Text);
ftpRequest.Method = WebRequestMethods.Ftp.ListDirectory;
FtpWebResponse response = (FtpWebResponse)ftpRequest.GetResponse();
StreamReader streamReader = new StreamReader(response.GetResponseStream());
List directories = new List();
string line = streamReader.ReadLine();
while (!string.IsNullOrEmpty(line))
{
directories.Add(line);
line = streamReader.ReadLine();
}

using (WebClient ftpClient = new WebClient())
{
ftpClient.Credentials = new NetworkCredential(txtusername.Text, txtpassword.Text);
string[] filename = txtftpaddress.Text.Split('/');
Filename = filename[filename.Length - 1];
string dirpath = localpath;
for (int k = 0; k <= filename.Length - 1; k++)
{
dirpath = (dirpath + "\\" + filename[k]).Replace(" ", "");
RD.createdir(dirpath);
}
try
{
for (int i = 0; i <= directories.Count - 1; i++)
{
if (directories[i].Contains("."))
{
string path = "ftp://xxx.xxx.xxx.xx//" + txtftpaddress.Text +"/" + directories[i].ToString();
ftpClient.DownloadFile(path, localpath);
}
else
{
string path = "ftp://us-atl-ftp01.spi-global.com//" + txtftpaddress.Text + "/" + directories[i].ToString();
string subdirpath = dirpath + "\\" + directories[i].ToString();
RD.createdir(subdirpath); //Create Directory
string[] subdirectory = RD.Return(path, txtusername.Text, txtpassword.Text); // getting sub-directory list
for (int j = 0; j <= subdirectory.Length - 1; j++)
{
string subpath = directories[i] + "/" + subdirectory[j];
directories.Add(subpath);
}
}
}
}
catch (WebException e)
{
String status = ((FtpWebResponse)e.Response).StatusDescription;
MessageBox.Show(status.ToString());
}
}
streamReader.Close();
}
catch (WebException l)
{
String status = ((FtpWebResponse)l.Response).StatusDescription;
MessageBox.Show(status.ToString());
}

@Karthi

Its quite difficult to understand what you are trying to achieve. I am quite sure that your code is not work properly.

Do you want to list all the folders and files contains in your ftp path and download each files accordingly.

Check the link for listing the files from ftp
http://www.c-sharpcorner.com/UploadFile/9b86d4/how-to-list-all-files-directories-from-a-ftp-server-in-C-Sharp/

To download the files, just you need to concatenate the files with your ftp domain name.

Do let me know, is that you are looking for.

Hi, this is my code amit. in this txtftpaddress.Text have the FTP file path.

try
{

FtpWebRequest ftpRequest = (FtpWebRequest)WebRequest.Create("ftp://xxx.xxx.xxx.xx/");
ftpRequest.Credentials = new NetworkCredential(txtusername.Text, txtpassword.Text);
ftpRequest.Method = WebRequestMethods.Ftp.ListDirectory;
FtpWebResponse response = (FtpWebResponse)ftpRequest.GetResponse();
StreamReader streamReader = new StreamReader(response.GetResponseStream());
streamReader.Close();
using (WebClient ftpClient = new WebClient())
{
ftpClient.Credentials = new System.Net.NetworkCredential(txtusername.Text,txtpassword.Text);
try
{
string[] filename = txtftpaddress.Text.Split('/');
string path = "ftp://xxx.xxx.xxx.xx//" + txtftpaddress.Text;
localpath = localpath + "\\" + txtftpaddress.Text.ToString().Replace("/", "-");
localpath = localpath.Replace(" ", "");
ftpClient.DownloadFile(path, localpath);
}
catch (WebException e)
{
String status = ((FtpWebResponse)e.Response).StatusDescription;
MessageBox.Show(status.ToString());
}
}
}
catch (WebException l)
{
String status = ((FtpWebResponse)l.Response).StatusDescription;
MessageBox.Show(status.ToString());
}

Please share the code to know which class you are using.

I think using WebClient class will provide more command over this
