Question

I have been using vb.net for a while. I am trying to figure out if there is a way that i can update file in a given folder to ftp and get any file on server back using vb.net

Is this Rocket Science or is it ok for intermediate programmer? Where should I start?

Answer 1

Depends on your needs for simple upload/download FtpWebRequest is enough.

If you however plan to list files/folders, compute checksums you can try http://Ftp.dll FTPS
component.

Using ftp As New Ftp
    ftp.ConnectSSL("ftp.server.com")
    ftp.Login("user", "password")

    ftp.ChangeFolder("uploads")
    ftp.Upload("report.txt", "c:\report.txt")

    Dim serverHash As Byte() = client.GetFileHash("report.txt", FtpHashType.CRC)

    ftp.Close()
End Using

Please note that this is a commercial product I created
