Question

i have this two method

public static void NavigateAndExecute(Node root, Action<Node> actionToExecute)
{
    if (root == null || root.Children == null || root.Children.Count == 0)
        return;
    actionToExecute(root);
    foreach (var node in root.Children)
    {
        actionToExecute(node);
        NavigateAndExecute(node, actionToExecute);
    }
}
public static void NavigateAndExecute(List<Node> root, Action<Node> actionToExecute)
{
    if (root == null || root.Count == 0)
        return;
    foreach (var node in root)
    {                
        NavigateAndExecute(node, actionToExecute);
    }
}

Node class is

public class Node
{
    public String Name { get; set; }
    public List<Node> Children { get; set; }
}

this two methods worked on just the Node class, can make them work on any type T
any help.

You want a Generic Tree Collection. I wrote one years ago which I’ve open-sourced:

I know the arguments against using Tree data structures, but sometimes they’re just what you need.
