Recursive class C#

Question

Can I define constructor like this? Additional question: Can I call constructor of the class in itself constructor?

class SubArray
{
    List<int> array;
    string parent;
    string name;
    SubArray child;

    public SubArray(SubArray child, string name)
    {
        this.child = child;
        List<int> array = new List<int>();
        this.name = name;
    }
}

In the code sample you provided you are NOT calling the constructor of SubArray from within the constructor of SubArray. — Alex Shtoff

have you tried? what was the result? Also what are you trying to do, add new subarray objects and set their properties or replace the existing properties in one object? — skyfoot

At the very least delegate the recursive part to a different method call. Constructors should not perform long running operations. — P.Brian.Mackey

There is no limit on that, but like any recursion - it needs a stopping condition. otherwise it will cause a stack overflow (PUN intended :)).

Extra kudos for the pun there. :)

I guess you could do something like this and there is no....apparent problem:

public SubArray(SubArray child, string name)
{
    this.child = child;
    this.array = new List<int>();
    this.name = name;

    if (child != null && child.child != null)
    {
        this.child.child = new SubArray(child.child,name);
    }
}
