==Simple Udp Client: send and receive==

<source lang="csharp">using System;
using System.Net;
using System.Net.Sockets;
using System.Text;
class MainClass
{
public static void Main()
{
byte[] data = new byte[1024];
string input, stringData;
IPEndPoint ip = new IPEndPoint(IPAddress.Parse("127.0.0.1"), 9999);
Socket server = new Socket(AddressFamily.InterNetwork,SocketType.Dgram, ProtocolType.Udp);
string welcome = "Hello";
data = Encoding.ASCII.GetBytes(welcome);

==Udp client setup==

<source lang="csharp">using System;

server.SendTo(Encoding.ASCII.GetBytes("message 1"), tmpRemote);

==Udp Multi-send==

<source lang="csharp">using System;

server.Bind(iep);

byte[] data = Encoding.ASCII.GetBytes("This is a test message");
server.SetSocketOption(SocketOptionLevel.IP, SocketOptionName.AddMembership, new MulticastOption(IPAddress.Parse("127.0.0.1")));
server.SetSocketOption(SocketOptionLevel.IP, SocketOptionName.MulticastTimeToLive, 50);
server.SendTo(data, iep2);
server.Close();
