Answer 1

While the example works, its not the correct way to handle the streams...

You need to ensure the closing of the files/streams with the using clause.. Also, add try/catch to handle IO errors...

       public void DownloadAll()
    {
        string host = @"sftp.domain.com";
        string username = "myusername";
        string password = "mypassword";

        string remoteDirectory = "/RemotePath/";
        string localDirectory = @"C:\LocalDriveFolder\Downloaded\";

        using (var sftp = new SftpClient(host, username, password))
        {
            sftp.Connect();
            var files = sftp.ListDirectory(remoteDirectory);

            foreach (var file in files)
            {
                string remoteFileName = file.Name;
                if ((!file.Name.StartsWith(".")) && ((file.LastWriteTime.Date == DateTime.Today))

                    using (Stream file1 = File.OpenWrite(localDirectory + remoteFileName))
                    { 
                        sftp.DownloadFile(remoteDirectory + remoteFileName, file1);
                    }
            }

        }
    }
