[c#] Implementare client tcp in codice WPF

[m.alverman]

Buona .... notte a tutti.
Sto pistolando con Kinect e ho trovato un po di codice che fa al caso mio.
Ora dovrei implentare un client tcp che invia i valori che stampo nella lblLeft e lblRight
Nel codice li ho evidenziati con 2 *

Mi date una mano per favore ?

Grazie, Alberto

E quindi? Vorresti scritto tutto il codice ?
