Have you tried anything with the code? and describe your question clearly.

i want to download multiple files from ftp server to local folder....
FtpWebRequest reqFTP;
//filePath = <<The full path where the file is to be created.>>,
//fileName = <<Name of the file to be created(Need not be the name of the file on FTP server).>>
FileStream outputStream = new FileStream(filePath + "\\" + fileName, FileMode.Create);

reqFTP = (FtpWebRequest)FtpWebRequest.Create(new Uri("ftp://" + txtip + "/" + fileName));
reqFTP.Method = WebRequestMethods.Ftp.DownloadFile;
//reqFTP.Method = WebRequestMethods.Ftp.ListDirectory;
reqFTP.UseBinary = true;
reqFTP.Credentials = new NetworkCredential(txtuser.Text.ToString(), txtpass.Text.ToString());
FtpWebResponse response = (FtpWebResponse)reqFTP.GetResponse();
Stream ftpStream = response.GetResponseStream();
long cl = response.ContentLength;
int bufferSize = 2097151;
int readCount;
byte[] buffer = new byte[bufferSize];

readCount = ftpStream.Read(buffer, 0, bufferSize);
while (readCount > 0)
outputStream.Write(buffer, 0, readCount);
readCount = ftpStream.Read(buffer, 0, bufferSize);

catch (Exception ex)

private void button1_Click(object sender, EventArgs e)
FolderBrowserDialog fldDlg = new FolderBrowserDialog();
if (txtupload.Text.Trim().Length > 0)
if (fldDlg.ShowDialog() == DialogResult.OK)
Download(fldDlg.SelectedPath, txtupload.Text.Trim());
MessageBox.Show("Please enter the File name to download");

i tried with the above code but only single file is downloading i need to download multiple files....

Step 3. Get a FTP client library or write one.

The last time I looked for a FTP solution for C# it required purchasing a library from a 3rd party vendor (I could have written one.)

An "example" requires writing to a specific API, which requires having the library in the first place.

And as I stated you need to do Step 2 first which isn't something that anyone else can do for you.

1. Determine how you will determine whether is is "updated" or not. Presumably via file time.
2. Get a FTP GUI client.
a. Insure that you can connect to the target FTP server.
b. Insure that you can see the update data (like file time.)
3. Get a FTP client library or write one.
4. Using 3 write code that does FTP steps. It will be similar to what you did via the GUI. Make sure that you check for and report error values.
