You could consider just taking the small hit and attempting to download the file. If it doesn't exist, an exception should be thrown and you can just catch it and move on. Checking for a file's existence is a volatile situation so in the majority of cases it's best to try and perform your action.

This should do the trick.

 using (var sftp = new SftpClient(host, username, password))
        {
            try
            {

                sftp.Connect();
                MessageBox.Show(sftp.Exists(remoteDirectory).ToString());
            }
            catch (Exception Sftpex)
            {
                MessageBox.Show(Sftpex.ToString());
            }
        }
