Question

I’m working on a project that heavily uses TreeView and TreeNodes. However, I need to remove the GUI from the existing program and allow it to run through in the console. I’m new to C# but I’m having trouble finding a similar class without the GUI. What would be the recommended class to implement? From what I understand there is no Tree base class but would I be able to create my own?

Thanks.

Trees are simply List<Node>s where Node is a class containing a List<Node> and any other important Data. How easy it is to implement depends on a lot of things, but you shouldn’t have much trouble:

public class Node<T> {
    private List<Node<T>> nodes;        

    public T Item { get; private set; }

    public Node(T item) {
        nodes = new List<Node<T>>();
        Item = item;
    }

    public IEnumerable<Node<T>> {
        return nodes;
    }

    //Add other things like: `Find(T item)`, `Add(T item)`
}

If you so desire you can create a Tree<T> class that encapsulates some searching/manipulating functions, but that should get you headed in the right direction.
