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


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).

  2. BradA says:

    Roy — as a mater of fact I will! In fact I will be at the book store on Wednesday 1:15-1:45… please drop by and see me!

  3. Roy J. Salisbury says:

    Brad — Good, this is right after Rico’s session, and the next block of time (1:45-3:00) has nothing of intrest.

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