How To Upload and Download Files with FTP from a VB.NET Application How To Use a Previously Created Custom Control in a New Application Serialize and Deserialize a Collection of Objects to a Data File. Download and install WS_FTP (trial version will work as well). Connect to your sFTP site via the hostname, username, and password. // Send Ftp Files - same idea as above - try. (C# and VB.NET) can be found here. The attempt here is to make it all concise and just get the sFTP transfer working quickly. Okay if i understand this correctly you want to list all files in a ftp directory with the word sport. Well first of all i always use a low levell ftp client, the advantage of this client is that it supports all FTP commands. Here it comes.

I want to make a VB.NET software in which we can select folders and add them in a listbox. These folders and their contents are to be uploaded to a FTP site at a certain amount of time. My question is that what's the code to upload folders and its contents to FTP site. The listbox only contains the main directory locations. There maybe multiple directories in the listbox. Button 3 is the uploadnow button which later on I will connect to the timer. Button 2 is for selecting the directories.
So far I have achieved this:

The WinSCP .NET assembly has the recursive transfer built-in.
Use the
Session.PutFiles
method like:See a full example.
Note that the
Session.PutFiles
(and the assembly overall) has synchronous interface (calls are blocking). So you need to execute the code from a separate thread, not from the GUI thread. Otherwise your interface will be unresponsive, while the transfer is proceeding.![How How](/uploads/1/2/6/0/126010904/507587217.gif)
To provide a progress feedback to the user, use the
Session.FileTransferProgress
event and the FileTransferProgressEventArgs.OverallProgress
property.(I'm the author of WinSCP)

You'll need to use the
System.Net.FtpWebRequest
class.Ftp Directory Structure
This is an untested-by-me example I found here (modified to use

We need to get about 100 very small files from a remote FTP server using vb.net.Our company won't let us buy (or install) any 3rd party ftp libraries... so we are forced to use something like FtpWebRequest. (Or is there a better free, choice that is already a part of Visual Studio?)
This method works, but it is VERY slow. (I assume because of the constant logging in/out.)
Instead, we probably should be doing this, but it never works:
Windows Default Ftp Directory
We found COUNTLESS examples online of 'getting an FTP file list' and later 'how to download 1 file with FTP'... but we never see 'get EACH file name, and download it NOW'.

Take a look at my FTP class, it might be exactly what you need.

Something I just put together, the important part is the fwr.Proxy = Nothing, otherwise it tries to auto get the proxy settings which causes huge delays so setting it to nothing forces it to not use one.
If you are using a proxy obviously you need to set this to an actual proxy.
I know its a bit late but hopefully helps
