For loop issue in C# (Networking)

Questions & Answers
1

I am pretty good with C# but when it comes to loops, I am lost. Be it while, for or any other that may exist I have no idea how to use them. I have translated the UnityScript code given on this page but this loop is giving me the only error from the whole file.

C# Translation

public class ServerCore : MonoBehaviour
{
    int maxClients = 10;
    int listenPort = 2943;
    NetworkPlayer p;

    void StartServer ()
    {
        Network.InitializeServer(maxClients, listenPort, false);
    }

    void StopServer ()
    {
        Network.Disconnect();
    }

    void OnGUI()
    {
        if (Network.peerType == NetworkPeerType.Disconnected)
        {
            GUILayout.Label("Network server is not running.");
            if (GUILayout.Button("Start Server"))
            {
                StartServer();
            }
        }
        else
        {
            if (Network.peerType == NetworkPeerType.Connecting)
                GUILayout.Label("Network server is starting up...");
            else
            {
                GUILayout.Label("Network server is running.");
                showServerInformation();
                showClientInformation();
            }
            if (GUILayout.Button("Stop Server"))
            {
                StopServer();
            }
        }
    }

    void showClientInformation()
    {
        GUILayout.Label("Clients: " + Network.connections.Length + "/" + maxClients);
        for(p in Network.connections) // Where I'm getting the error
        {
            GUILayout.Label(" Player from ip/port: " + p.ipAddress + "/" + p.port); 
        }
    }

    void showServerInformation()
    {
        GUILayout.Label("IP: " + Network.player.ipAddress + " Port: " + Network.player.port);
    }
}

Original

var listenPort = 25000;
var maxClients = 5;
 
function startServer() {
    Network.InitializeServer(maxClients, listenPort, false);    
}
 
function stopServer() {
    Network.Disconnect();
}

function OnGUI ()
{
    if (Network.peerType == NetworkPeerType.Disconnected) {
        GUILayout.Label("Network server is not running.");
        if (GUILayout.Button ("Start Server"))
        {               
            startServer();  
        }
    }

        {               
            stopServer();   
        }
    }
}
 
function showClientInformation() {
    GUILayout.Label("Clients: " + Network.connections.Length + "/" + maxClients);
        for(var p: NetworkPlayer in Network.connections) {
        GUILayout.Label(" Player from ip/port: " + p.ipAddress + "/" + p.port); 
    }
}
 
function showServerInformation() {
    GUILayout.Label("IP: " + Network.player.ipAddress + " Port: " + Network.player.port);  
}

This form of loop in C# uses ‘foreach’:

 foreach(NetworkPlayer p in Network.connections)
