static void xmppCon_OnPresence(object sender, Presence pres)
     {
         dataaa:

         PrintInfo(String.Format("Got presence from: {0}", 
pres.From.ToString()));
         PrintInfo(String.Format("type: {0}", pres.Type.ToString()));
         PrintInfo(String.Format("status: {0}", pres.Status));
         PrintInfo("");

         if (!pres.From.ToString().Contains(jid.Bare.ToString()))

         {
             PresenceManager pm = new PresenceManager(xmppCon);
             pm.ApproveSubscriptionRequest(pres.From);

             xmppCon.Send(new Message(pres.From, MessageType.chat, "Спасибо что добавил"));
         }
         //{
         //
