C# TreeView aus Code erstellen

Question

Wie kann ich aus C# Code heraus (ohne Designer) Elemente zu einem TreeView hinzufügen?

using System;
using System.Collections.Generic;
using System.Windows.Forms;

namespace WinFormsApp1 {

    public partial class Form1 : Form {
 
        public Form1() {
            InitializeComponent();
            InitializeTreeView();
        }

        private void InitializeTreeView() {
            TreeView treeView1 = new TreeView();
            treeView1.Location = new System.Drawing.Point(10, 10);
            treeView1.Size = new System.Drawing.Size(200, 300);
        }
  
    }

}

Indem du TreeNodes erstellst.

TreeNode rootNode = new TreeNode("Root Node");

rootNode.Nodes.Add(new TreeNode("Child Node 1"));
rootNode.Nodes.Add(new TreeNode("Child Node 2"));

treeView1.Nodes.Add(rootNode);
