Connect to more than 1 sftp

[jeffwest21]

I am trying to set up a system to pull data from more than 1 sftp site at timed intervals during the day.

I have found a piece of work that someone else did that does it from one, but I need to as I say from a second as well.

The code I have in the app config is this.

    <appSettings>    
    <add key ="Extra1" value ="folder1/"/>
    <add key ="Extra2" value ="folder1/folder2/"/>
  </appSettings>

<sftp remoteHost="sftp.blah.blah.blah" port="22" username="user" password="password" rootPath ="/folder/folder/folder/folder/ "> </sftp>

I then have this is a download manager

 DirectoryInfo localRootInfo = new DirectoryInfo(ConfigurationManager.AppSettings["ToProcessFolder"].ToString());
            DirectoryInfo localSubRootInfo = localRootInfo.CreateSubdirectory(string.Format("{0:yyyyMMdd-HHmmss}", DateTime.Now));

            string Directory1 = ConfigurationManager.AppSettings["Extra1"];
            string Directory2 = ConfigurationManager.AppSettings["Extra2"];

            using (SftpManager sftp = new SftpManager())
            {
                // Loop through all of the folders and download if file available - NB These contain the WAV Files
                foreach (var directory in sftp.GetAllDirectories(sftp.RootDirectory))
                {
                    //string remoteWorkingFolder = string.Format("{0}{1}", sftp.RootDirectory, directory);
                    string subfolderName = Path.Combine(localSubRootInfo.FullName, directory.Name);
                    DirectoryInfo serviceLocalSubFolderInfo = new DirectoryInfo(subfolderName);

                    foreach (var file in sftp.GetAllFiles(directory.FullName))
                    {
                        if (!serviceLocalSubFolderInfo.Exists) serviceLocalSubFolderInfo.Create();

                        string localFilename = Path.Combine(serviceLocalSubFolderInfo.FullName, file.Name);

what I want to do is add the Directory1 then Directory2 into the rootPath in order to do this, but nothing I do seems to work, it just fails, however, if I add the entire path into the rootPath then it works, so I know the connection is right, just the added bit is wrong.
