Microsoft Edge URL

Question

I've been searching for code that gives me urls that are searched currently in Microsoft edge

I tried below code, it works till current window is Edge and then it gives null at tabelement

using System;
using System.Runtime.InteropServices;
using System.Windows.Forms;
using Interop.UIAutomationClient;

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

    private void Form1_Load(object sender, EventArgs e)
    {
        timer1.Start();
    }

    [DllImport("user32.dll")]
    private static extern IntPtr GetForegroundWindow();

    private void timer1_Tick(object sender, EventArgs e)
    {
        const int UIA_NamePropertyId = 30005;
        const int UIA_ClassNamePropertyId = 30012;
        const int UIA_NativeWindowHandlePropertyId = 30020;


        IUIAutomation uiA = new CUIAutomation();
        IUIAutomationElement rootElement = uiA.GetRootElement();

        IUIAutomationCacheRequest cacheRequest = uiA.CreateCacheRequest();
        cacheRequest.AddProperty(UIA_NamePropertyId);

        IUIAutomationCondition windowCondition = uiA.CreatePropertyCondition(UIA_NativeWindowHandlePropertyId, GetForegroundWindow());
        IUIAutomationElement windowElement = rootElement.FindFirstBuildCache(TreeScope.TreeScope_Descendants, windowCondition, cacheRequest);
        if (windowElement == null)
        {

        }
        else
        {

            IUIAutomationCondition edgeCondition = uiA.CreatePropertyCondition(UIA_NamePropertyId, "Microsoft Edge");
            IUIAutomationElement edgeElement = windowElement.FindFirstBuildCache(TreeScope.TreeScope_Subtree, edgeCondition, cacheRequest);
            if (edgeElement == null)
            {

            }
            else
            {

                IUIAutomationCondition tabCondition = uiA.CreatePropertyCondition(UIA_ClassNamePropertyId, "TabWindowClass");
                IUIAutomationElement tabElement = edgeElement.FindFirstBuildCache(TreeScope.TreeScope_Descendants, tabCondition, cacheRequest);
                if (tabElement == null)
                {

                }

                else
                {

                    IUIAutomationCondition ieCondition = uiA.CreatePropertyCondition(UIA_ClassNamePropertyId, "Internet Explorer_Server");
                    IUIAutomationElement ieElement = edgeElement.FindFirstBuildCache(TreeScope.TreeScope_Descendants, ieCondition, cacheRequest);
                    if (ieElement == null)
                    {


                    }
                    else
                    {

                        string url = ieElement.CachedName;
                        string title = tabElement.CachedName;
                        MessageBox.Show(url, title);
                    }

                }

            }

        }
    } 
}
}

If anyone knows why it is happening please do help and if any better code is available to get current url please post
Thanks

This test works for me (code tested in a click on a Button...) =>

IntPtr hWndEdge = IntPtr.Zero;
System.Diagnostics.Process[] procEdge = System.Diagnostics.Process.GetProcessesByName("msedge");
if (procEdge.Length <= 0)
    Console.WriteLine("Microsoft Edge is not running");
else
{
    foreach (System.Diagnostics.Process proc in procEdge)
    {
        if (proc.MainWindowHandle == IntPtr.Zero)
            continue;
        else
        {
            hWndEdge = proc.MainWindowHandle;
            break;
        }
    }
}
if (hWndEdge != IntPtr.Zero)
{ 
    IUIAutomation pUIAutomation = new CUIAutomation();
    IUIAutomationElement windowElement = pUIAutomation.ElementFromHandle(hWndEdge);
    if (windowElement != null)
    {
        IUIAutomationElementArray elementArray = null;
        IUIAutomationCondition condition = null;
        condition = pUIAutomation.CreateTrueCondition();
        elementArray = windowElement.FindAll(TreeScope.TreeScope_Descendants, condition);
        IUIAutomationElement elementAddressBar = null;
        if (elementArray != null)
        {
            int nNbItems = elementArray.Length;
            for (int nItem = 0; nItem <= nNbItems - 1; nItem++)
            {
                IUIAutomationElement element = elementArray.GetElement(nItem);
                string sName = element.CurrentName;
                string sAutomationId = element.CurrentAutomationId;
                Console.WriteLine("Name : {0} - AutomationId : {1}", sName, sAutomationId);
                IUIAutomationElement5 element5 = (IUIAutomationElement5)element;
                int nLandmakType = element5.CurrentLandmarkType;
                if (nLandmakType == 80004) // UIA_LandmarkTypeIds.UIA_SearchLandmarkTypeId
                {
                    elementAddressBar = element;
                    break;
                }
            }
            if (elementAddressBar != null)
            {
                Object pPattern = null;
                pPattern = elementAddressBar.GetCurrentPattern(10018); // UIA_PatternIds.UIA_LegacyIAccessiblePatternId
                if (pPattern != null)
                {
                    IUIAutomationLegacyIAccessiblePattern pLegacyIAccessiblePattern = (IUIAutomationLegacyIAccessiblePattern)pPattern;
                    String sValue = pLegacyIAccessiblePattern.CurrentValue;
                    MessageBox.Show(String.Format("Current URL = {0}", sValue), "Information", MessageBoxButtons.OK, MessageBoxIcon.Information);
                }
            }
        }
    }
}
