  Dim reader As SSHStream = sftp.Get("file.txt")
  Dim writer As BinaryStream = BinaryStream.Create(SpecialFolder.Desktop.Child("file.txt"))
  
  Do Until reader.EOF
    writer.Write(reader.Read(1024))
  Loop
  
  reader.Close
  writer.Close

  Dim sftp As New SSH.SFTPSession(session)
  Dim writer As SSHStream = sftp.Put("file.txt")
  Dim reader As BinaryStream = BinaryStream.Open(SpecialFolder.Desktop.Child("file.txt"))
  
  Do Until reader.EOF
    writer.Write(reader.Read(1024))
  Loop
  
  reader.Close
  writer.Close

List directory

This example lists a remote directory using SFTP:

  Dim session As SSH.Session = SSH.Connect("ssh://user:[email protected]/")

  Dim names() As String
  Dim lister As SSHStream = sftp.ListDirectory("/path/to/dir/")
  
  Do Until lister.EOF
    names.Append(lister.Read(1024))
  Loop
  
  lister.Close
