The requested operation caused a stack overflow

I am trying to create a derived class and the error pops up. Not quite sure how it comes out. Please help!

Base class: 

public class Command : identifiableobject
{
    LookCommand l = new LookCommand();

    public virtual string Execute (Player p, string[] text)
    {
        return "";

    public Command (string[] ids) : base(ids)
    {
    }
}

Derived class

public class LookCommand : Command
{
    public LookCommand () : base (new string[] {"look"})
        {
        }
}

The error pops up when I try to create a new Command Object. Any ideas why?

This is the problem:

public class Command : identifiableobject
{
    LookCommand l = new LookCommand();

    ...

That means that in order to construct a Command, you need to construct a new LookCommand. But a LookCommand is a Command, so constructing one LookCommand requires constructing another one, which constructs another one, etc.

We don't know what you're trying to achieve with the l variable here, but that's what's causing the Either you need to get rid of that variable, or don't initialize it in that way, or make LookCommand not derive from Command.
