            }

        }

Variabler

En variabel er noget som indeholder en værdi. Det kunne eksempelvis være brugerens navn der bliver indtastet i programmet, og gemt i en værdi.

Værdityper er som følgende:

Variabler
Type	værdi
string	"Dette er tekst"
int	9001
float	123.45
bool	true/false

Middel hold

Opgave 1:

Lav en BMI beregner som denne:

http://www.beregnbmi.dk/Default.aspx

Opgave 2:

Lav en lommeregner lignende den som findes i Windows.

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

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

Lommeregner eksempel:

Serializerings eksempel:

            //Opretter et GameData objekt:
            GameData gd = new GameData();
            gd.playerMoney = 100;

            //Hvad vi skal bruge til at serializere:
            XmlSerializer serializer = new XmlSerializer(typeof(GameData));
            StringWriter sWriter = new StringWriter();

            //Serializering af objekt:
            serializer.Serialize(sWriter, gd);

            //Opretter en string med alt XML:
            string myXml = sWriter.ToString();

            //Udskriver XML fil til skrivebordet. BEMÆRK at du skal ændre filstien for at det virker:
            //File.WriteAllText(@"C:\Users\MaKN\Desktop\save.xml", myXml);

            //Indlæsning af XMLfil fra skrivebordet:
            string readXML = File.ReadAllText(@"C:\Users\MaKN\Desktop\save.xml");
            Console.WriteLine(readXML);

            //Deserializering af xmlfil til objekt:
            StringReader sReader = new StringReader(readXML);
            GameData newGD = (GameData)serializer.Deserialize(sReader);

            //Udskriver den nye værdi fra det nye objekt:
            Console.WriteLine("New GameData money value is: "+ newGD.playerMoney);
            Console.ReadKey();

GameData klasse: (husk at lave den public)

    [Serializable]
    public class GameData
    {
        public int playerMoney = 0;
        public int playerUpgrades = 0;
    }

Expert hold

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();

Serializering:

            Human joshua = new Human();
            joshua.name = "Joshua";
            joshua.money = 20000;

            XmlSerializer serializer = new XmlSerializer(typeof(Human));
            StringWriter sWriter = new StringWriter();

            serializer.Serialize(sWriter, joshua);

            string myXml = sWriter.ToString();

            Console.WriteLine(myXml);
            Console.ReadKey();

            StringReader sReader = new StringReader(myXml);

            Human newJoshua = (Human)serializer.Deserialize(sReader);
            Console.WriteLine("New Human was created!");

            Console.WriteLine(newJoshua.name);
            Console.WriteLine(newJoshua.money);
            Console.ReadKey();

Opgave:

Send et objekt fra et program til et andet program igennem UDP eller TCP.
