The SLAR (vol2) on System.Net.Sockets.AddressFamily

  • Article

Looks like the SLAR vol2 finally made its way to book sealer’s warehouses which means everyone that pre-ordered should be getting their copy soon. I’d love to hear what you think and I’d encourage you to help your fellow developers by posting a review on Amazon and\or on your blog.

In honor of this day, I thought I’d restart the series sharing some of the information in the .NET Framework Standard Library Annotated Reference Vol 1 and .NET Framework Standard Library Annotated Reference Vol 2 with some information on AddressFamily (the first type in Vol2)

public enum AddressFamily

{

AppleTalk = 16,

Atm = 22,

Banyan = 21,

Ccitt = 10,

Chaos = 5,

Cluster = 24,

DataKit = 9,

DataLink = 13,

DecNet = 12,

Ecma = 8,

FireFox = 19,

HyperChannel = 15,

Ieee12844 = 25,

ImpLink = 3,

InterNetwork = 2,

InterNetworkV6 = 23,

Ipx = 6,

Irda = 26,

Iso = 7,

Lat = 14,

MS Max = 29,

NetBios = 17,

NetworkDesigners = 28,

NS = 6,

Osi = 7,

Pup = 4,

Sna = 11,

Unix = 1,

Unknown = -1,

Unspecified = 0,

VoiceView = 18,

}

This list was derived mainly from the winsock header files. While the socket classes included in

v1 of the .NET Framework are mostly geared around IP-based communication, it is possible to

use the EndPoint class to support other protocols such as IPX, AppleTalk, Infra Red, and so

forth.

using System;

using System.Net;

using System.Net.Sockets;

using System.Text;

public class AddressFamilySample

{

   public static void Main()

   {

     IPAddress ip = IPAddress.Parse("127.0.0.1");

     Socket skt = new Socket(AddressFamily.InterNetwork,

     SocketType.Dgram, ProtocolType.Udp);

     try

     {

        IPEndPoint ep = new IPEndPoint(ip, 9999);

        skt.Connect(ep);

        byte[] req = Encoding.ASCII.GetBytes("Test");

        skt.SendTo(req, ep);

        IPEndPoint rep = (IPEndPoint)skt.LocalEndPoint;

        Console.WriteLine("LocalEndPoint details:");

        Console.WriteLine("Address: {0}", rep.Address);

        Console.WriteLine("AddressFamily: {0}", rep.AddressFamily);

        Console.WriteLine("Port: {0}", rep.Port);

     }

     catch (Exception e)

     {

    Console.WriteLine("Error: " + e.Message);

     }

     finally

     {

        skt.Close();

     }

     Console.WriteLine();

     Console.WriteLine();

     Console.WriteLine("Press Enter to continue");

     Console.ReadLine();

   }

}

The output is

LocalEndPoint details:

Address: 127.0.0.1

AddressFamily: InterNetwork

Port: 4082

Press Enter to continue

    I can only assume that you will have a BIG STACK of these books available at the PDC for a book signing (hard cover editions please).

    Volume 2 of the book that Brad affectionately calls the "SLAR" has been published!  He stopped by...
