Answer 1

Hi Kalel111,

I'm not quite familiar with FTP stuff, but I'm trying to provide you some information.

I do think that most of the samples are using Windows.Networking.BackgroundTransfer to implement the FTP download action. This feature is ideal for large file downloads and upload operations using the HTTP and HTTPS protocols. FTP is supported, but only when conducting download operations.<//span>

Here is a sample using WebRequest to communicate with the FTP server, I don't know if method "STOR" can be used to upload somthing.

Best regards,

First, go Package.appxmanifest file and assign Capabilities to Internet(Client) and Internet(Client & Server)

To upload a file to FTP server RustemSoft Skater development Team developed the following function:

Public Async Function FTP_Uploader(ftpURL As String, filename As String, username As String, password As String, UploadText As String) As Task(Of Boolean)
            Try
                Dim request As WebRequest = WebRequest.Create(ftpURL + "/" + filename)
                request.Credentials = New System.Net.NetworkCredential(username.Trim(), password.Trim())
                request.Method = "STOR"
                Dim buffer As Byte() = Encoding.UTF8.GetBytes(UploadText)
                Dim requestStream As Stream = Await request.GetRequestStreamAsync()
                Await requestStream.WriteAsync(buffer, 0, buffer.Length)
                Await requestStream.FlushAsync()
                Return True
            Catch ex As Exception
                Return False
            End Try
End Function

Jamles,

I tried using WebRequest, but no success.

Keep trying other possibilities.
