Şu C# kodunu kabaca açıklayabilecek biri var mı ?

selam, 

özelden yolladığın kod zaten benzeri. aslında yaptığı iş kabaca, kendi veritabanınıza bağlanıp bekleyen sms leri, turkcell objesini kullanarak, turkcell'in sistemlerine gönderiyor. Aşağıda ilk birkaç satırı açıkladım. Ondan sonrakiler de tekrar zaten. 

 

if (vtgtw.conn.State != ConnectionState.Open) // veritabanı bağlantısı açık değilse
                {
                    vtgtw.Open(); // veritabanına bağlan
                }

                if (vtdwh.conn.State != ConnectionState.Open) // ayrı bir veritabanı bağlantısı, açık değilse
                {
                    vtdwh.Open(); // onu da aç
                }

                Queue<int> lstidrsms = new Queue<int>(); // içinde int tipinde veri depolayacak nesneyi oluştur
                IHebe iht = new HEBESMSPostpaid(); // turkcell sistemine bağlanacak nesneyi oluştur
                String tsesid = iht.Register(); // oturum id'sini turkcell'den al

                {
                    MySqlCommand mcom9 = vtdwh.getCommand(600000); //mysql komutunu oluşturacak nesneyi oluştur
                   
mcom9.CommandText = "SELECT s.idrsms FROM sentsmscount AS s WHERE
(s.s2>0 or s.se1>0) AND s.senddate>=DATE_ADD(NOW(), INTERVAL
-10 DAY)"; // veritabanında çalıştırılacak sql sorgusu
                    MySqlDataReader mdr9 = mcom9.ExecuteReader(); // bu sorguyu okumaya başla
                    while (mdr9.Read()) // tabloda kayıt olduğu müddetçe aşağıdaki işlemi yap
                    {
                        lstidrsms.Enqueue(mdr9.GetInt32(0)); // büyün kayıtları bir yerde topla. (kuyruğa at)
                    }
                    mdr9.Close(); // az evvel yukarıda açılan objeyi kapa
                    mdr9.Dispose(); // dispose ederek memoryde kapladığı alanı boşalt
                    mcom9.Dispose(); // aynı dispose işlemini buna da uygula
                }

                while (lstidrsms.Count > 0) // yukarıda enqueue ile toplanan verilerde işlem yapmaya başla
