CspParameters cp = new CspParameters(); cp.KeyContainerName = "25522100"; string usb = ":RIO"; string Name = System.Environment.MachineName; Name += usb; mymsg = ENC(Name, cp); clint(mymsg);


SERVER :

mytcp = new TcpListener(7000); mytcp.Start(); mysocket = mytcp.AcceptSocket(); myns = new NetworkStream(mysocket); BinaryFormatter br = new BinaryFormatter(); object op; op = br.Deserialize(myns); data = (byte[])op; MessageBox.Show(data.Length.ToString()); //////////////////////
.
