Opgave 1:
Lav et program der kan sende data til en applikation som kan lytte. Benyt gerne UDP.
Opgave 2:
Udvid programmet så programmerne kan både sende og modtage data til hinanden. (et simpelt chat program.)
Listener
UdpClient client = new UdpClient(11000);
IPEndPoint endPoint = new IPEndPoint(IPAddress.Any, 11000);
byte[] recivedArray = client.Receive(ref endPoint);
string message = Encoding.ASCII.GetString(recivedArray);
Console.WriteLine("The message was:");
Console.WriteLine(message);
Console.ReadKey();
Sender
string message = "Hello!";
UdpClient client = new UdpClient();
IPEndPoint endpoint = new IPEndPoint(IPAddress.Parse("127.0.0.1"), 11000);
byte[] bArray = Encoding.ASCII.GetBytes(message);
client.Send(bArray, bArray.Length, endpoint);
Console.WriteLine("Message has been sent!");
Console.ReadKey();
