looping through a collection of servers and ports

Question

I want to loop through a collection of servers and ports (3 of each to be exact) and try to make a connection, once a connection is made I can move on with the rest of the code.. here is what i have.

        IRC_SETTINGS IRC; //3 servers & 3 ports.
        foreach (string SERVER in IRC.IRC_SERVERS)
        {
            try
            {
                ircSocket = new TcpClient(SERVER, PORT);
                break; //;when we have a working connection.
            }
            catch(Exception){}
        }

I guess that works fine for the servers part, but how do I go about looping through the ports at the same time? something like foreach (string server, int port in ....

You can put them into single data structure (e.g. list) and them loop through them:

public class IrcServer
{
    public string Name { get; set; }
    public int Port { get; set; }

    // perhaps some methods
}

IList<IrcServer> servers = new List<IrcServer>();

foreach(IrcServer server in servers)
{
    // server.Name, server.Port
}

Update

Since you have two different arrays (one for server names and one for port numbers) you can merge them using into dictionary:

int[] ports = { 1, 2, 3 };
string[] servers = { "one", "two", "three" };

var serversWithPorts = servers.
    Zip(ports, (s, i) => new { s, i }).
    ToDictionary(i=> i.s, i => i.i);

foreach(var server in serversWithPorts)
{
    Console.WriteLine(server.Key + ":" + server.Value);
}

dumb question but then where do I define the servers and ports? :/ I have already a class with a string array of servers and an int array of ports... – ace007 Oct 28 '12 at 10:20
So you have two different arrays and you don't want to make single structore out of it? – Zbigniew Oct 28 '12 at 10:21
I've edited my question, also take a look at [this SO question](http://stackoverflow.com/questions/6133362/how-to-unifiy-two-arrays-in-a-dictionary) – Zbigniew Oct 28 '12 at 10:27
just decided to go with this ircSocket = new TcpClient(IRC.IRC_SERVERS[i], IRC.IRC_PORTS[i]); and increase "i" if there's a connection error. seems to work.. – ace007 Oct 28 '12 at 10:28
No problem, I thought about using loop counter (`i`), but I assumed that you would rather use one structure instead of two arrays, so I assumed further that your problem was more like: how to tie togheter two arrays. – Zbigniew Oct 28 '12 at 10:34
