Recursively search nested lists

Question

I\'ve read and searched and I\'m yet to figure out an answer to this relatively simple issue.

I have a class:

public class AccessibleTreeItem
{
    publ         


        

Answer 1

public class AccessibleTreeItem
{
    public string name;
    public List<AccessibleTreeItem> children;

    public AccessibleTreeItem()
    {
        children = new List<AccessibleTreeItem>();
    }

    public static AccessibleTreeItem Find(AccessibleTreeItem node, string name)
    {

        if (node == null)
            return null;

        if (node.name == name)
            return node;

        foreach (var child in node.children)
        {
            var found = Find(child, name);
            if (found != null)
                return found;
        }

        return null;
    }
}
