Netværks programmer
Opgaver:
Opgave1:
Lav et program, der kan lytte efter en besked.
Opgave2:
Lav et chat program, hvor en server og klient kan sende og modtage beskeder til og fra hinanden.
UDP listener:
Server:
UdpClient client = new UdpClient(11000);
IPEndPoint endpoint = new IPEndPoint(IPAddress.Any, 11000);
byte[] recivedBytes = client.Receive(ref endpoint);
Console.WriteLine("The message was:");
string result = Encoding.ASCII.GetString(recivedBytes);
Console.WriteLine(result);
Console.ReadKey();
UDP client:
Server:
UdpClient client = new UdpClient();
IPEndPoint endPoint = new IPEndPoint(IPAddress.Parse("127.0.0.1"), 11000);
byte[] myBytes = Encoding.ASCII.GetBytes("Hello!");
client.Send(myBytes, myBytes.Length, endPoint);
Console.WriteLine("Message has been sent!");
Console.ReadKey();
Threading
Server:
static void Main(string[] args)
{
Console.WriteLine("Start");
Thread thread = new Thread(myThread);
thread.Start();
string input = Console.ReadLine();
Console.WriteLine(input);
Console.ReadKey();
}
static void myThread()
{
for (int i = 0; i < 10; i++)
{
Console.WriteLine(i);
}
}
Onsdag
Object to XML and Back
Opgave 1:
Lav et program der kan konvertere et objekt til XML, og sende det igennem UDP. Når UDP pakkerne når frem, skal de deserialiseres tilbage til et objekt igen.
Program:
Human joshua = new Human();
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 mads = (Human)serializer.Deserialize(sReader);
Console.WriteLine("This is the player Mads:");
Console.WriteLine(mads.money);
Console.WriteLine(mads.upgrades);
Console.ReadKey();
Human:
public class Human
{
private float myWeight;
public float MyWeight
{
get {
Console.WriteLine("Half-Life 3.. Worth the weight!");
return myWeight;
}
set { myWeight = value; }
}
public string name = "Joshua";
public float money = 2000.0f;
public int upgrades = 0;
}
