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:
| Type | værdi |
|---|---|
| string | "Dette er tekst" |
| int | 9001 |
| float | 123.45 |
| bool | true/false |
Færdig gør denne lommeregner:

Færdiggør dette spil (Tic Tac Toe):

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);

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.
