Populating TreeListView from existing hierarchy list

I have a list of objects called Items, that I want to display in a Treelistview in a hierarchy. The objects look like this:

public class ListItem
{
    public int ID;
    public string LabelText;
    public int ParentID;
    public bool Checked;
}

The list order ensures that parents are always defined first. Now I want to iterate over this list and build my hierarchy in the Treelistview. When I dectect a parent in the object I can search the already created nodes on the ListView and search for the ID, but I was wondering if it is possible to create the TreeNodes dynamically with the ID as the reference, like so (bit of pseudo code);

foreach (ListItem Item in Items)
{
  TreeNode {Item.ID} = new TreeNode()
  {
    Checked = Item.Checked,
    Text = Item.LabelText
  };

  if (Item.ParentID == null)
    DropDown.Nodes.Add({Item.ID});
  else
    {Item.ParentID}.SubItems.Add({Item.ID});
}
