Umleiten von standard-Eingabe von Konsole-Anwendung

Hier ist eine Klasse, die ich geschrieben habe, um zu behandeln, dass Art von Sachen. Fühlen Sie sich frei, es zu benutzen. Sein Zweck ist es, starten Sie eine Konsole-Anwendung und zu "reden". Es hat die Fähigkeit zu empfangen-Ausgang als auch. Viel Glück.
