Middel hold

Opgave 1:

Lav en BMI beregner som denne:

For at konvertere en string til en decimal bruges følgende kode:

string input = textBox.Text;
decimal convertedInput = decimal.Parse(input);


Lommeregner eksempel:

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();
