Return an array of strings?

Question

So on my game server we have server-side commands. I was wondering if it was possible to turn this

public string Command
{
    get { return "g"; }
}

into something like this

public string Command
{
    get { return "g", "guild", "group"; }
}

Here's the command interfaces code

internal interface ICommand
{
    string Command { get; }
    int RequiredRank { get; }
    void Execute(Player player, string[] args);
}

Here's the command handler's code
part 1:

ProcessCmd(x[0].Trim('/'), x.Skip(1).ToArray());

part 2:

private void ProcessCmd(string cmd, string[] args)
{
    if (cmds == null)
    {
        cmds = new Dictionary<string, ICommand>();
        var t = typeof (ICommand);
        foreach (var i in t.Assembly.GetTypes())
            if (t.IsAssignableFrom(i) && i != t)
            {
                var instance = (ICommand) Activator.CreateInstance(i);
                cmds.Add(instance.Command, instance);
            }
    }

    ICommand command;
    if (!cmds.TryGetValue(cmd, out command))
    {
        psr.SendPacket(new TextPacket
        {
            BubbleTime = 0,
            Stars = -1,
            Name = "*Error*",
            Text = "Unknown Command!"
        });
        return;
    }
    try
    {
        ExecCmd(command, args);
    }
    catch (Exception e)
    {
        Console.Out.WriteLine(e);
        psr.SendPacket(new TextPacket
        {
            BubbleTime = 0,
            Stars = -1,
            Name = "*Error*",
            Text = "Error when executing the command!"
        });
    }
}

Answer 1

You want this:

public string[] Commands
{
    get { return new string[] {"g", "guild", "group"}; }
}

Start with this. It will produce errors you should fix and by advancing in the fixing you will refactor a nice portion of code, like the ICommand interface.
