What type of list<> should I use to hold data in a winforms treeview?

public class MyClass
{
	public List<MyClass> MyChildren { get; set; }
	public MyClass MyParent { get; set; }
}

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace WindowsFormsTreeView
{

	public partial class Form1 : Form
	{
		MyClass FirstElement;
		public Form1()
		{
			InitializeComponent();
			FirstElement = new MyClass() { Name = "I am first" };


			FirstElement.MyChildren.Add(new MyClass() { Name = "SecondLevel" });
			MyClass oneMoreElement = new MyClass() { Name = "Something" };

			FirstElement.MyChildren[0].MyChildren.Add(oneMoreElement);
			//now we have a tree. this is not simple array.

		}

		private void button1_Click(object sender, EventArgs e)
		{
			GetAllFrom(FirstElement , this.treeView1.Nodes);
		}

		

		private void GetAllFrom(MyClass LevelElement, TreeNodeCollection treeNodeCollection)
		{
			TreeNode anyLevel = new TreeNode();
			anyLevel.Text = LevelElement.Name;
			treeNodeCollection.Add(anyLevel);
			foreach (MyClass anyChild in LevelElement.MyChildren)
			{
				GetAllFrom(anyChild , anyLevel.Nodes);
			}

		}		
	}


	public class MyClass
	{
		List<MyClass> myChildren;
		public List<MyClass> MyChildren
		{
			get
			{
				if (myChildren == null)
				{
					myChildren = new List<MyClass>();
				}
				return myChildren;
			}
			set
			{
				myChildren = value;
			}
		}

		//public MyClass MyParent { get; set; }
		public string Name { get; set; }

		
	}
}
