サンプルコード

using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.Linq;
using System.Threading;
using System.Windows.Automation;
using System.Windows.Forms;
using System.Drawing;


class FormMain: Form {
	private TreeView tv;
	FormMain() {
		Text = "Edge UI";
		Size = new Size(700, 700);
		tv = new TreeView();
		tv.Location = new Point(20, 20);
		tv.Size = new Size(600, 600);
		this.Controls.Add(tv);
		this.Load += new System.EventHandler(this.Form_Load);
	}
	private void Form_Load(object sender, System.EventArgs e) {
		Process process = Process.Start(@"C:\Program Files (x86)\Microsoft\Edge\Application\msedge.exe", "https://auctions.yahoo.co.jp");
		Thread.Sleep(2000);
		process = UpdateTargetProcess("Yahoo!オークション - 日本最大級のネットオークション・フリマアプリ");
		AutomationElement mainForm = AutomationElement.FromHandle(process.MainWindowHandle);
		TreeNode tn = new TreeNode(mainForm.Current.Name);
		WalkEnabledElements(mainForm, tn);
		tv.Nodes.Add(tn);
	}
	private static Process UpdateTargetProcess(string title) {
		Process process = null;
		foreach (Process p in Process.GetProcesses())
		{
			if (p.MainWindowTitle.Contains(title))
			{
				process = p;
				break;
			}
		}
		if (process == null)
		{
			Console.WriteLine(title + "のプロセスが見つかりません。");
		}
		return process;
	}
	private void WalkEnabledElements(AutomationElement rootElement, TreeNode treeNode) {
		Condition condition1 = new PropertyCondition(AutomationElement.IsControlElementProperty, true);
		Condition condition2 = new PropertyCondition(AutomationElement.IsEnabledProperty, true);
		TreeWalker walker = new TreeWalker(new AndCondition(condition1, condition2));
		AutomationElement elementNode = walker.GetFirstChild(rootElement);
		while (elementNode != null)
		{
			TreeNode childTreeNode = treeNode.Nodes.Add(elementNode.Current.Name);
			WalkEnabledElements(elementNode, childTreeNode);
			elementNode = walker.GetNextSibling(elementNode);
		}
	}
	[STAThread]
	public static void Main() {
		Application.EnableVisualStyles();
		Application.SetCompatibleTextRenderingDefault(false);
		Application.Run(new FormMain());
	}
}

以上。
