View source for CSharp:Multithreading Windows Form UDP TCP Tester

==TCP vs UDP==
Essenzialmente:
* UDP è più veloce del TCP perché i pacchetti sono inviati senza garantire la consegna;
* TCP è sicuro perché ogni pacchetto ha la conferma e l'ordine.
Ottima guida [https://www.skullbox.net/tcpudp.php skullbox.net]

==Codice completo==
E' una Windows app che fa da simulatore client e server UDP. Il codice è predisposto anche per il TCP ma non è stato ultimato. <br />
Ci sono 2 TAB, uno per il test del "Talker" che è il client che invia testo ed uno per il "Listner" che funge da server. E' camblato dentro l'IP a cui entrambe i ruoli fanno riferimento.
